Radar Sensor NivoRadar® NR 3100 for level measurement

The challenge:

A fertilizer producer requires a solution to control high precision measurement of sulfuric acid in 4-meter tanks. Due to the material being highly corrosive, chemical resistance was vital when selecting the process material.  Quick signal response and accuracy were also important as the instrument should control subsequent processes.

The solution:

UWT has a suitable solution with the non-contact level transmitter, Nivoradar 3100 with 78Ghz frequency and the signal response of ca. 10 seconds. The plastic lens antenna made of PEI and high precision of 5mm together with stainless steel flange and stainless-steel housing were important to increase the efficiency of the process.

Capacitance point level detection in liquid naphthalene

Capacitance point level detection in liquid naphthalene – A point level measurement to avoid overfilling or emptying is required in almost all process containers today. In the chemical industry, sensors are usually exposed to aggressive, adhesive, or caustic materials. The measurement technology must deal with high temperatures, varying DK values, and viscosity fast and efficiently. To meet these conditions in practice, system planners are increasingly using the capacitive rod probes.

Precision & process compatibility through adaptable point level detection

A leading chemical manufacturer, mainly processing naphthalene derivatives in addition to carbon, coal tar, pitch, and special oils required reliable and robust level monitoring, which could be flexibly adapted to fluctuating ambient conditions.

As a combustion product of organic materials, naphthalene occurs in low concentrations almost everywhere in the environment and can be used as a contaminant, e.g. in carbon blacks, which are used for blackening, and in mineral oils, which are used as plasticizers. Another application is in the production of solvents, plastics, fuel additives, and insecticides.

Capacitance point level detection in liquid naphthalene
Capacitive RFnivo® for overfill protection in liquid naphthalene. Process conditions: changing temperature, caking and inconsistent DK values.

In the liquid state, naphthalene is an aggressive substance that quickly corrodes common materials. If it becomes firmer as it cools down, it tends to become heavily attached.  Tests concluded that tanks can be constantly monitored using the capacitance measuring principle of UWT’s robust RFnivo® probe. The RF series are adaptable rod probes, which due to their design do not require any temperature-restricting components for media detection and can, therefore, be used smoothly in processes up to 500°C. They work with the capacitive measuring principle, whereby the capacitance is measured regardless of the length of the sensor of the medium between the probe tip and the container wall.

Active Shield Technology
Through the integrated “Active Shield” technology the RF limit switch delivers precise measurement results despite strong buildup of the naphthalene

The chemical manufacturer has several storage tanks that are electrically heated to maintain the melting point of the naphthalene. There is a process pressure of approx. 0.8 bar (11.6 psi). The DK value fluctuates between 1.6 and 2.0. Each tank was equipped with a RFnivo® installed on the overflow line for full notification to ensure reliable protection against the overfilling of the containers. When the material is removed, the temperature drops rapidly causing caking on the sensor boom. Overflow line being there at a height of 1700mm, the installed RF probes work within this overflow line under constantly changing process temperatures (max. up to 80°C (176°F). The “Active Shield” technology integrated as standard in the RF probe ensures that the measurement result is not influenced in the long term by the buildup on the probe. The storage tanks could thus be provided with a reliable content monitoring system, which, due to the design, can optimally adapt to the changing environmental conditions, which meant the optimal support of a smooth and maintenance-free manufacturing process for the plant operator. Special attention was also paid to the aspect of process safety in chemical plants. A certified design in accordance with international approvals according to ATEX, IEC-Ex, FM, FMc, etc. qualifies the RFnivo® for the safety standards of this demanding industry.

What is important to the operator?

The RFnivo® calibrated itself after mounting and wiring in the box after power was applied. The operator had to do nothing further but set the signal output in the QuickStart menu after its application. If an RFnivo® is used in an application to which the supply voltage has already been applied, only the calibration button needs to be pressed after installation in the container. The probe automatically adjusts to the new application. Thus, the calibration of the RFnivo® is easily performed. For “diehard” RF probe operators, there is also a powerful manual and menu-driven calibration. This ultimately leads to the same result as the automatic calibration.

The universal voltage electronics are clearly equipped with a display and 3 control buttons and provide a DPDT signal output for signal evaluation. During operation, the display will always show the capacity measured now.

Parameters such as FSH (fail save high) and FSL (fail save low) as well as reaction time of the signal output can be clearly arranged in a quick start menu. A test button allows the manual start of a self-diagnosis of the sensor. If required, an automatic self-diagnosis can be set, which then regularly checks the correct function of the RFnivo® and activates the failsafe in case of error. This self-diagnostic runs in the background without affecting the function of the probe in the application.

More solutions with the capacitance series for level measurement in liquids, pastes and foams

After gaining valuable experience within liquids applications, UWT has expanded its portfolio to include compatible solutions for all liquids, pastes and foams. The RFnivo® 8000 series was included in the RFnivo® level switch series, which is especially suitable for the detection of pasty, adhesive and corrosive liquids as well as for foam detection. It can also be used for interface measurement of different liquids or sludges and is with WHG and according to Lloyd’s Register certified. The compressive strength of this RF version is up to 35bar. The optionally available PFA coating also provides improved chemical resistance. The devices are equipped with encapsulated electronics and work with the innovative Inverse Frequency Shift Technology, which allows a very precise sensitivity adjustment to the medium. Due to the variation of versions with rod and tube extensions, the sensors can be easily adjusted to the respective container conditions and installation situations.

Capacitive Capanivo® CN 7

UWT solution in animal feed

UWT solution in animal feed – Capacitive measuring sensors are the all-rounders amongst limit switches as they have the highest application performance in the basic version. They can be found in overfill protection as well as the demand and empty indicators in process or storage vessels as well as in leakage monitoring and interface detection and can be used in all tank types and shapes, regardless of whether the vessels are metallic or non-metallic. Due to their high sensitivity & compactness, they are particularly suitable for the different process requirements of the feed industry.

 A well-known animal feed manufacturer implemented the Capanivo® capacitive level detector from UWT GmbH within its mixing tanks for blending processes. With its reliable media detection and short reaction time, the sensor helps to ensure the correct mixing proportion of the individual components, the homogeneous distribution, and the lasting quality of the end product.

Precise media detection with adherent raw materials

During animal feed production, similar processes occur in all production sites, such as within the mixer. An important step is the mixing of flour or pellets with liquid raw materials such as molasses, vinasse, oils, fat, or choline. The Capacitive sensors offer optimum support for the detection of filling levels in material handling processes due to their high compatibility for different process containers. The material to be inspected can have a completely different nature depending on the processing stage and can impose different requirements on the measuring technique to be used.

With 40 years’ experience and more than 1 million successfully solved applications in the area of bulk material measurement, UWT GmbH provides smart solutions with a new capacitive sensor series in applications for liquid measurement. The devices are equipped with potted electronics and work with the innovative “Inverse Frequency Shift” technology. They have a robust, certified design and offer smart solutions for all liquids, pastes, and foams. Through the variation of versions with cable, rope as well as rod and tube extensions, the sensors can be easily adjusted to the respective vessel conditions and can also be used for interface detection in liquids.

The animal feed manufacturer installed the integral version of the capacitive Capanivo® CN 7100 limit sensor. When touched by a medium, the sensor reacts to the change in capacitance on the probe arm, whereby a signal output is then switched. The universally applicable two-wire switch is particularly suitable for limited space conditions due to its unique compact design. Besides the version with connection cable, a housing version and a complete plastic version are also available. The CN 7100 guarantees a safe flow of media within the mixer despite vibrations and the fact that some of the liquids are viscous and adherent, which is compensated by the integrated “tip sensitivity”.

With its reliable media detection and short reaction time, it helps to ensure the correct mixing proportion of the individual components, the homogeneous distribution as well as the lasting quality of the end product. Approximately 50-100 kg liquid components of various liquid media are added to about 3 tons of solid content, in the mixers. These are injected into the mixing container within one minute by a special injection device. For this purpose, the various liquids are injected from storage tanks or mobile containers (GRP), with a pressure of up to 5 bar, into the mixing container via a distributor attached to the mixer. The Capanivo® CN 7100 level switch installed in the distributor ensures both that the liquid intended by the control system is present in the distributor (= media detection) and at the same time is available in sufficient quantity, thus guaranteeing the correct and quantitative supply to the various formulations.

A challenge of the plant is that only one distribution device is attached to the mixer. This is fed with the different liquids one after the other, pressure is built up and from there the liquids are then distributed to injection lines and pumped into the mixer at different points. The design of the sensor used implies food-conforming materials and is universally applicable. It detects all liquids with the highest degree of safety even if the previous liquid still adheres in one layer to the sensor and inside the distribution device and is only rinsed out by the subsequent liquid. All these requirements are met by the UWT Capanivo® CN 7100.

Agriculture, food, beverage & pharmaceutical – Clean in place (CIP) solutions

Project: CIP installation planning and construction

A complete sensor system for efficient certified and approved CIP cleaning for a prominent company specializing in the transport and logistics of liquid food.

The application

The CIP system consists of four tanks for freshwater, cleaning agents, returns and wastewater and the parallel cleaning system for up to three trucks. The independent process lines are designed for a fast, hygienic operation that is equally optimized in terms of ecological and economic aspects. From the tanks installed in the basement, cleaning media is pumped upwards into the milk or food trucks and flow back from there through hydrostatic pressure. In contrast to the otherwise frequently practiced “lost process “, the circulation and multiple recycling of the cleaning agents was a crucial requirement due to environmental protection and cost aspects.

The advantages of the application

  • Complete process sensor technology for reliable and sustainable CIP cleaning from a single source
  • Inline measurement of critical parameters enables precise process control and thus a verifiable quality for the certification of the cleaning
  • High measuring accuracy and short reaction times ensure resource efficiency (e.g. saving of cleaning agents, reduction of wastewater volume) a crucial requirement here due to environmental protection and cost aspects.

The CIP cleaning takes place in three stages:

1. Pre-rinsing with water from the return tank

2. CIP cleaning with 1-phase cleaner, then depending on concentration either recirculation into cleaning agent tank or discharge into return tank

3. Flushing with fresh water with discharge into the return tank

For reliable and certifiable cleaning and maximum utilization of the cleaning agents, temperature, conductivity and flow rate must correspond exactly to the specifications. These values are controlled permanently and with the utmost precision inline.

For all applications in the overall process, the Anderson-Negele sensors were able to offer the appropriate solution, thus ensuring optimum function, efficiency and process reliability for the customer.

The Solution

Different measuring methods ensure process reliability for the tanks. Capacitive level detectors NCS-M-11, installed at the top and bottom, transmit the full or empty signal to the PLC with the shortest reaction time in order to reliably prevent overflow during filling or pump idling. Type L3 pressure sensors are used for permanent volume measurement and to monitor the exact filling level. The temperature is continuously measured by dead-leg optimized TFP-161 sensors.

For correct cleaning, the media must always be pumped into the truck and their integrated spray heads with a specified, optimum pressure. Installed right after the pump, electromagnetic flow meters FMQ and pressure transmitters DANHH accurately monitor this process step. After the cleaning process, the media are analyzed inline and their return to the corresponding tanks is monitored by calorimetric flow switches of type FTS-141.

The analysis of the return media is one of the most important steps for an environmentally friendly and cost-efficient process. The ILM-4 inductive conductivity meter plays a central role in precisely determining the phase separation: during the discharge of the liquids at each cleaning stage the media are differentiated with cost-saving accuracy. Re-usable cleaning agent that flows off after cleaning can thus be returned to the tank to the maximum possible degree. In a separate, internal circulation and for permanent optimum cleaning result, its concentration is adapted to the specified ideal value by re-dosing with detergent and fresh water in the cleaning agent tank. The ILM-4 conductivity meter also ensures the highly precise measurement of conductivity and temperature required here.

OIL & GAS – Refinery automation


SensoTech’s LiquiSonic® is an inline analytical system for determining the concentration in liquids directly in the running process without delay. The device is based on meticulous measurement of the absolute sonic velocity and process temperature allowing for the detection of phase transitions.

 Phase separation in pipelines

The accurate detection of various phases in a pipeline is necessary for several industries. Often multiple products flow through the same pipe, but every single product is supposed to end in a different location. In applications in which product A is discharged by product B, the intermediate phase is to be separated.

Safety aspects are closely connected in applications with high-risk potential. In particular, the monitoring in multi-fuel pipelines for the petrochemical industry provides not only data about the product quality (incoming goods), but also avoids incorrect filling of storage tanks and thus serious accidents.

In the petrochemical industry, contrasting fuels are conveyed over long distances in just a pipeline. Here the rapid detection of the different products as well as the quality monitoring is focused.

 Phase separation in batch processes

In batch processes, the product phases are separated due to the physical and chemical properties of each product.

Application example: biodiesel/glycerol

In the manufacture of biodiesel, glycerol is produced as a by-product. The mixture of the two substances is conveyed in large settling tanks and then has several hours to separate. The LiquiSonic® sensors are usually installed into the outlet of the tank. By the detection of the phase transitions, the valve is activated and the biodiesel and the glycerol are supplied to the processing. The intermediate phase returns to the separation process.

 Phase separation in continuous processes

In a continuous process, one or more sensors control the separation of a process stream. In this instance, only the phase-specific value of sonic velocity is monitored and kept constant.

Frequently, the product concentration of the carrier phase varies in the inlet. This quickly shifts the height of the phase boundary. Thus, the carrier phase could be pulled off with the product, which greatly affects the purity. In process the separation is made via one pump in each of the two outlet pipes.

The advantages of the LiquiSonic® measuring and analyzing technology are both the rapid response time of less than 1 s and the connection of up to four sensors to only one LiquiSonic® controller. The controller processes all measuring values and passes the data to the process control system. Depending on the type of vessel and process objectives different installation

variants are possible.

Hygienic limit switches for processes

Process and storage vessels incorporate Hygienic limit switches to prevent overfilling of a tank or vessel (full indicator) or dry running of a pump (empty indicator). Anderson-Negele’s NCS series are ideally suited for the reliable measurement of limits in media with low water content, such as certain alcohols and cosmetics, providing universal application in bottling and pharmaceutical applications.

Capacitive working principle

Anderson-Negele level switches operate on the basis of the capacitive working principle. The measuring electrode, the medium and the conductive wall of the tank form an electrical capacitor influenced by three main factors: distance; area of the electrode surfaces; and type of medium between the electrodes.

The measuring electrode and the tank wall serve as the capacitor plates while the medium acts as the dielectric fluid. Due to the higher dielectric constant of the medium relative to air, the capacity increases when the electrode is immersed in the medium. Exposing the electrode has the opposite effect. The change in capacity is analysed by the level switch and converted to a corresponding switching command. The sensor outputs a 24 V DC signal (active output). The minimum and maximum (full/empty) switching functions can be swapped by reversing the polarity of the power supply. The capacitive working principle requires that the sensor tip, which is made of PEEK, be completely immersed in the medium. The advantage is that the sensor does not respond to foam or adherences and a signal is emitted only when the medium reaches the level. Capacitive measurement is most reliable when the dielectric conductivity and temperature of the medium are constant. Changes in the outer conditions are generally non-critical in media with high dielectric constant values.

Rotary paddle switch with rope extension for point level measurement in silos

Rotary paddle switch – Level Measurement & Control

Rotary paddle switch with rope extension for point level measurement in silos

February 2020 Level Measurement & Control

A motor-driven shaft causes the vane to rotate. Once the material level reaches the vane, thereby preventing further rotation, this creates a torque, which is converted via a switch to an electric signal. Once the vane is free again of the material, the output signal is reset, and the motor-driven shaft rotates again. This dependable and maintenance-free limit switch for safe level detection in bulk solids has international approvals for use in gas and dust hazardous areas and is also certified to SIL

The RotoNivo offers a universal voltage power supply, 24 V DC to 220 V AC. It can be connected to the same unit without any alterations being made and with the absence of additional power supply to the unit, for example, in very old plants, is completely nullified. This makes it easy for a processing plant to keep one version in stock that can be used in various applications on different parts of the plant. UWT suits the unit to your application, to ensure complete reliability and effectiveness.

February 2020 Level Measurement & Control

Morton Controls in partnership with Anderson-Negele has introduced the innovative NSL-F High-speed level measurement sensor based on a modular device platform. The new platform strategy used with this sensor is based on a building-block principle that offers great flexibility in the assembly of individual sensor components.

Users benefit from the advantages of the system and profit from the reliability with which these sensors provide measurements, even in strongly adhesive and foaming media. For example, the device will accurately display that a tank is empty even in the presence of substantial foam. Due to the short response time, highly accurate metering processes can be reliably realised with the NSL-F – even with alternating and pasty media.

Anderson Negele’s specific Flex-Hybrid technology allows for easy operation of the sensor with either digital IO-Link or analog 4-20 mA technology, as well as in parallel with both interfaces. Other features include:

• Status control and sensor diagnosis for preventive maintenance and avoidance of production downtime.

• Interference-free plug-and-play technology with standard cable for time and cost-saving installation and commissioning.

• Uniform configuration for all sensors without the need for company-specific programming adaptors.

• Easy sensor replacement: automatic detection, configuration and parameterisation when plugged in.

Applications include continuous level monitoring in metallic vessels up to 3 m in height, level monitoring in feed vessels suited for adhesive and pasty media, level measurement in storage tanks of foaming media, and content measurement in pressurised vessels.

Content measurement in Silos and storage hoppers remastered

UWT has taken the old-time rock ‘n roll method of content measurement in Silos and storage hoppers and remastered it to perfection, enabling seamless integration with our modern-day control systems and PLC’s. The UWT NivoBob continuous level measurement system offers a high-tech Approach version of a simple and very reliable measurement principal:

The basic working principle is as follows:

  • Sensor weight drives down on a measuring rope/ tape.
  • The rope/ tape length is electronically measured by the rotation of the internal rope/ tape roller
  • Material contact stops movement and the rope/ tape relieve for a short time
  • Motor changes the direction of rotation
  • Sensor weight is driven back to the upper stop position
  • The distance is measured, and signal outputs are activated (pulse/ relays/ 4-20mA/ Modbus/ Profibus)


THE CHALLENGE:  Content measurement for silos – The level measurement should be carried out in storage silos for gypsum powder. The finished product is conveyed pneumatically into the storage silo after production. The overall production planning is difficult if the fill level monitoring of the storage silos is missing. The operator previously had to climb onto the silo roof and carry out a manual level measurement with a rope and a weight. This yielded inaccurate results and caused huge losses in stock management and control. The task was to automate the level measurement and to avoid manual measurements.

THE SOLUTION:  The UWT lot system Nivobob 3200 in the tape version fulfills these extreme requirements. The integrated tape cleaner prevents contamination of the band interior. The Nivobob 3200, thereby, provides a reliable measurement that can be totally trusted. Neither very dusty nor clumpy conditions adversely affect the UWT Lot system. The electromechanical sensor NB3200 is developed for dusty applications and for high process temperatures and is the best solution in this gypsum storage.

THE PRODUCT:  NB 3200 Tape Version

When it comes to ignoring the cone after filling or the upside-down pyramid after draining the silo/ bunker, and achieving reliable, accurate measurement results, Physics and experience play a role. To get to this, the NivoBob must be mounted 1/3rd from the radius of the silo to accurately cancel out the cone effect you will get.


Reliable empty alarm in cosmetics tank

Reliable empty alarm in cosmetics tank

Economy and ecology in harmony through automatic monitoring of the filling line – Reliable empty alarm in cosmetics tank with NCS-L-12/18   

For over 60 years, the French brand Yves Rocher has been synonymous with high-quality cosmetics based on vegetable raw materials. The company is strongly committed to ecological issues and biodiversity. Even small factors such as the optimal use of raw materials play a role.

  1. The application

The filling systems for cosmetic creams were previously controlled manually. The filling level in the buffer tank had to be monitored by an employee and the filling process had to be stopped manually at the appropriate moment.

In order to prevent the filling pump from running dry, the process was stopped for safety reasons at an early stage, leaving important quantities of cream in the tank. This residual product was then disposed of, resulting in a significant loss of value.

Application advantages

  • Significantly lower product losses due to optimal emptying of the tank during filling
  • Precise measurement results despite high viscosity of the cream and corresponding adherences to the sensor probe
  • No manual control and monitoring required
  • Fast amortization through reduction of product losses and time savings for employees
  1. The solution

With the NCS-L level sensor, the filling process is automated. Due to its special sensor shape with 18 mm length and its measuring method with an extended measuring range, the NCS-L-12/18 is particularly suitable for low-water, viscous media such as oils, syrups or even cosmetic creams. Due to its inline integration in the outlet pipe of the filling system, the sensor signals safely and reliably as soon as the cream is depleted, thus stopping the filling process automatically.

  1. The result
  • Cream losses are minimized.
  • The quantities of waste to be disposed of (cream remaining in the tank) is reduced.
  • Impurities (splashes due to dry running of the filling pump) are avoided.
  • Maximum process reliability for the personnel operating the filling system
