Precise Measurement with Sensotech’s Liquisonic Sensors

For a more precise and quicker measurement of concentration and density, look no further than the Sensotech Liquisonic Sensors.

 

In particular Sensotech have had much success in the many sectors from chemical to the  brewing industry. While they use a standard system, there is also fine-tuning to customise the solution to the specific food industry specifications and hygienic requirements.

 

INSTALL AND FORGET

It is rare in an industry, where keeping tabs is the norm, to find a company that promotes walking away and letting the system manage the process alone. And that really is the case here! Sensotech’s Liquisonic sensors are that in tune, that once they have been set up correctly, they will monitor continuously.

 

Multiple signals are sent out every second and combined into one compensated signal. The temperature of the medium and the drifts are taken into account during single measurements. No matter what is happening with the conductivity and colour of the medium, the measurements continue. They are also resistant to pressure shocks.

 

The Liquisonic sensors are manufactured to be maintenance and drift-free for a period of 15-20 years. If you were concerned about drift in measurement before, no need to with SenorTech.

 

WHAT IS THE UNIQUE CONCEPT BEHIND THESE SENSORS?

sensors

The fast reaction time of these sensors using absolute sonic velocity as a well-defined and retraceable physical value means phase separation is quicker than before, with more accuracy. You are getting a reproducible physical signal that is quite unique handling temperature rangers of  up to 180 °C or 200 °C and can be use in explosion areas as well.  Solid rugged sensors for a precise and fast density and concentration measurement using absolute sonic velocity as a well-defined and retraceable physical value.

The positioning of the Liquisonic sensors is key in the application, be it in the main vessel or piping. The sensors are available to suit your process connections, such as tri-clamps, varivents or flanged.

The electronics can be housed inside a enclosures form polyester to stainless steel casing (IP 69) or in an existing cabinet.

 

THE STORAGE OF DATA

 

The Sensotech  controller can have up to four sensors connected for management of up to 32 (optional 99) products with an output of concentration and temperature, trend chart for a fast process course overview with  simple parameterization, e.g. of periphery analog and digital outputs, fieldbus, and Ethernet. It has a automatic self-monitoring function with a simple installation und intuitive operation for recording of events, e.g. exceeding of thresholds or change of product plus long-term memory of measuring results and user management with authorization levels. Remote operation via browser (PC, tablet, etc.)standard is to provide data storage that is situated internally as well as a card slot this way you can store the measurements for longer periods of time.

 

LET’S TALK APPLICATIONS

 

There are many variations and applications where the Liquisonic sensors can be applied. Namely:

 

Phase Interface Detection

Gas Scrubber Control

Concentration & Density Measurement

Refrigeration Cycle Monitoring

D3_1-Remote-Flush-Mount-Short_F-Trans

D3 Differential Pressure & Level Transmittor

Focusing on the Food, Beverage, Dairy and Life Sciences industry, we bring you Anderson-Negele’s D3 Differential Pressure and Level Transmittor.

Using the Modular Platform of Anderson-Negele sensors and the technology of L3 it has a parallel display of differential pressure and head or system pressure in the display and two mA output interfaces. The electronics using digital signalling to avoid negative impact of temperature changes reduces the effects of process and ambient temperature changes quite significantly. One of the elements we like about the D3 is that it comes ready to use out-of-the-box and the simple setup and programming is just that – simple.  You can mount the D3 transmittor display direct or you can mount the two sensors remotely and insuring a reliable remote wire cabling.

Take a look at some of the applications where this transmittor has worked well.

THE RANGE OF APPLICATIONS FOR THE D3 DIFFERENTIAL PRESSURE AND LEVEL TRANSMITTOR

 

  • In yoghurt culture vessels for Level monitoring
  • In fermentation vessels for Level monitoring
  • In Mashtuns for grain bed monitoring
  • Across membranes for pressure drop measurement

WHAT ARE THE MAIN FEATURES?

 

As mentioned, the setup couldn’t be easier with the user interface display.  You are provided with two analogue outputs, the top or bottom pressure and the differential pressure output.  In addition, the temperature compensation which will minimise any errors in extreme temperature changing applications plus simple and reliable remote wire cable avoid frequent recalibration

 

Should there be a need to replace or repair components, this can be done in the field with ease and no interruption to the work process as there are no capillary issues!  On inputting the product and tank information, you will receive accurate mass and volume output due to the integrated tank tables.  The patented dual o-ring seals give you IP69K ingress protection and you can look forward to the dual loop output provided by the Hart 7.0 graphical and communication LCD display.

 

WHAT IS THE MEASURING PRINCIPAL OF THE D3 DIFFERENTIAL PRESSURE AND LEVEL TRANSMITTOR

 

In the D3 system, each sensor uses an internal piezo-electric signal converter and a temperature sensor to measure the pressure and temperature of the capillary fill.  The electrical signal of the pressure converter and the resistance of the temperature sensor are measured and converted to a compensated pressure value in the pressure fitting. Both signals are transferred digitally to the head. They are then output in a standardized 4…20 mA and HART 7.0 signal for the differential pressure and in a 4…20 mA signal for the top or total pressure.

 

Where you have level applications that have pressure and/or vacuum conditions, we highly recommend the D3 Differential Pressure and Level Transmittor from Anderson-Negele.

anderson-negeleilm4

Anderson-Negele’s ILM-4 – Uniquely accurate and more powerful than ever before

When you are on a tight schedule and budget, being able to minimize resources and maximise product reliability is always first prize.  Anderson-Negele’s ILM-4 Conductivity Sensor can do this and so much more.

 

Anderson-Negele’s ILM-4 – Economical and Consistent

Two words that speak to the innovativeness of the ILM-4.  One area that can drive costs up in the Food and Beverage industry, is too high levels of concentrations of the cleaning agent in the tanks.  Other issues are inadequate cleaning results because of too low levels.  ILM-4’s conductivity sensors ensure optimization so that the correct levels are sustained and that they reduce the quantities of chemicals used.

 

What Happens during Cleaning Phase?

There are a few factors that are taken into account during the cleaning phase, so that a safe process runs:

  • The exact concentration of cleaning agent
  • Time
  • Temperature

How is this done?

The cleaning solutions are identified based on their specific conductivity as they flow back out of the plant.  They are then fed back into the appropriate stack tanks i.e. Base, acid and water via downstream valves.

As mentioned, temperature plays an integral role in this process.  With optimized temperature response time, Anderson-Negele’s ILM-4 conductivity sensor can differentiate between wash and rinse cycles, thus producing a further cost savings in reducing safety margins.

 

Improvements – more powerful, flexible and modular

Due to the successful history of the ILM series, Anderson-Negele has been able to feed in the ILM-4 with ease.  It is even more powerful and offers more comfort and flexibility.  Because it is compatible with its predecessor models, it can be easily integrated into any existing process.

All adjustments can be made quite simply on the device display or via a laptop. One can adjust the measurement ranges quite freely and the calibration function allows calibrating by the plant operator onsite.  In addition, any replacement of components, can also be made onsite which saves in maintenance costs and time.

cip system

The CIP System – Within the F&B Industry

In food manufacturing, cleaning-in-place or the CIP system is a standard component for ensuring reliable and efficient adherence to quality standards. The requirements placed on sensors, used for process control, are particularly high in the food and beverage industry.  They are tailored solutions for optimizing the CIP process, using turbidity and conductivity sensors.

What is involved?

The CIP system consists of numerous interlinked steps. Plant operators need to take into account more than just the downtime of the system. Costs also arise from the consumption of water, chemicals and energy, as well as product loss.

The sequence of the individual cleaning cycles is often still time-controlled. These fixed cleaning intervals will guarantee that the system is always cleaned properly.  However, more water, and cleaning solution and time, may be consumed than would actually be necessary for the medium being processed.

What is the solution?

The solution is to automate control of the CIP system using turbidity and conductivity sensors. The average water consumption, depending on the product, is 1.5 to 3 liters per processed liter of product.  Half of this water is used for cleaning the system.

Are there disadvantages?

A disadvantage of cleaning processes with fixed time intervals is that the maximum required cleaning duration must be used for each cleaning cycle. For example, the removal time for pasty media is considerably longer than for less viscous products. Therefore, when performing CIP cleaning after producing media with less viscosity, more water is used than is necessary.

This, however, can be remedied through automated process control using the turbidity and conductivity sensors. Water consumption at large F&B manufacturing plants can be lowered from an average of 6,500 to 2,500 liters per cleaning cycle simply by deploying an intelligent phase detection system. This will result in savings of water and wastewater costs.

In addition, shorter cleaning cycles lead to a lower consumption of acids and bases.  The use of chemicals can be precisely controlled by measuring their concentrations using the conductivity sensor, allowing their consumption to be further optimized.

What are the production-related stats?

Experience has shown that production-related losses reach 0.5% in large operations and 2.5% in small operations. It is particularly the plants with low levels of automation that experience significant losses in product.

The precise and rapid detection of water-to-product phases using the turbidity sensor lead to reductions in product losses of 5–10% in customer field projects. A CIP system usually takes 60–90 minutes. A hygienic design of the entire system is therefore an important contributor to shortening the cleaning cycles and increasing the efficiency and productivity of the process.

How can Morton Controls help?

As a specialist for sensor systems in hygienic processes, we, at Morton Controls, have sensors and process connections that are optimally designed for the demanding requirements of the F&B industry and that ensure reliable and efficient cleaning of the system.

Sensotech – Steel and Rolling Mills

In the steel production, Sensotech uses the LiquiSonic® measuring technology, which optimizes operations.  The reason, briefly, for using this technology is because of the possibility of saving chemicals, such as acids and cooling lubricants, without influencing the surface finish negatively.

We will explain the following processes in this blog: Pickling and Acid Regeneration.

To catch up with us on the other processes, namely, Cold Rolling, Electrogalvinizing, and Roller Chrome Plating, tune in for another blog coming soon.

Pickling

Pickling baths are used downstream of the hot rolling process, and also in many other fields in the metal-working industry, to remove, passivate, modify, and clean surfaces in a defined manner.

And so, pickling solutions are employed, which consist mainly of a mixture of mineral acids.  The concentration of these acids decreases during the pickling process, however the portion of distributing components, such as contaminations and carry-over increases.

The LiquiSonic® Measuring technology provides a solution for online measurements of pickling bath concentrations facilitating redosing of the required quantity of fresh acid.  This ensures a continuous optimum pickling bath quality.  Delays in time as a result of sampling and lab analyses are avoided.

These are the successful pickling bath applications where LiquiSonic® has been used:

  • Sulturic acid (H2SO4)
  • Phosphoric acid (H3FO4)
  • Hydrochloric acid (HCI)
  • Nitric acid (HNO3)
  • Hydrofluoric acid (HF)

Acid Regeneration

In this process, the acid is refreshed and removed of all contaminations, such as iron salt.  The most popular procedure used is the crystallisation for the recovery of sulturic acid.  In addition, the spray roasting or buttering-floating procedure is used, for the recovery of hydrochloric acid.

Before the used pickling acids are cleaned, they are evaporated to concentrate the acid.  The acid is then separated, and the cleaned acid is added to the pickling process.  The resulting metal oxides are used as valuable raw materials in other industry sectors.

After evaporation, the LiquiSonic® 40 system is used to determine the acid and the metal salt apart from each other.  The last part of the process is when the LiquiSonic® 30 system is used to detect the acid concentration solely, as the metal salts have been removed before.
