SUSPENDED SOLID SENSORS – GET BETTER CONTROL

For better control over your suspended solids, we recommend Quadbeam’s S-range of suspended solid sensors, both for hygienic and immersion capabilities.

In addition, you will realise cost savings, a reduction in losses, and higher concentration control, in a repeated and accurate manner.

 

THE MAIN FEATURES OF THE S-RANGE SUSPENDED SOLID SENSORS

  1. Because of the 4-beam self-compensating sensor, drifting is eliminated and therefore electronics aging and contamination is done away with
  2. You have one-piece piece casing and therefore no leakage in the lenses – completely glass-free
  3. These sensors are reliable, repeatable and accurate

Quadbeam offers a number of models in their suspended solid sensors, namely:

Under Hygienic –

– S10-3HY

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

Evaporator

Neutralization

Incoming Goods Control

Bath Monitoring

Polymerization Monitoring

Solids control in pulp and paper (green, red and black liquor)

 

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.

UWT T30

THE T30 PROCESS TURBIDITY SENSORS FROM QUADBEAM

Quadbeam Technologies has two models available, the Immersion T30-IMM and the Hygienic T30-3HY.

 

Utilising Quadbeam’s four beam ratio-metric technology, with the 90 degrees Scattered and the Attenuated NIR, meeting ISO7027 standards, making it a truly unique turbidity sensor proving its reliability, repeatable ability and accurate measurement in many situations.

 

The measurement range is between 0 and 50 through to 0 to 1000NTU.  Note that these measuring ranges will change dependent on the media and particle size. The simple user interface is easy to calibrate, and you will find you will have much better control over many processes.

 

Both Immersion and Sanitary configurations are available with Hygienic 3A certified and Immersion Styles Airjet Cleaner of Immersion Style approved.

 

SOME COMMON APPLICATIONS WITH THIS TURBIDITY METER

 

  • Clarifier overflow weir monitoring
  • Steam condensate and cooling water returns
  • Surface water monitoring
  • Solids that are loaded in streams and rivers
  • Condensation water monitoring
  • Filtration control and monitoring
  • Measuring percentage solids in vegetables and fruit
  • On plate heat exchangers – product breakthrough control
  • From DAF plants, final outlet of effluent measurement
  • Dairy plant loss control

 

 

MORE ON THE T30

 

There are two emitters and two detectors, which are set at 90 degrees to each other.  As they pulse in sequence, two detector currents are produced, one from the detector at 90 degrees to the emitter (scattered light) and one from the detector opposite the emitter (attenuation). A Ratio-metric four beam signal processing compensates for changes in optical properties of emitters and detectors due to ageing and surface coating.

 

A standard built-in cleaner is available with the T30 submersible turbidity sensor from Quadbeam.  The recommended cleaning method is with high pressure air with an optional biocide included. To protect the sensor fingers from impact, stainless steel support rods are designed to lift and protect the sensor fingers in rugged applications.

What is the Measuring Principal of the Relative Turbidity Meter?

 

An infrared diode infrared light is irradiated into the media.  Particles in the media are reflected by the irradiated light, which in turn is detected by the receiver diode (the backscatter principle).

From the received signal, the electronics will calculate the relative turbidity of the media.  The relative turbidity is based on Anderson-Negele’s calibration standard and is displayed in “%TU”.

Case Study: Anderson-Negele and Rotkäppchen-Mumm Sektkellereien

A practical application was undertaken of conductivity measurement during tartar stabilization in wineries.  Anderson-Negele’s conductivity meters for process control during tartar stabilization at Rotkäppchen-Mumm Sektkellereien GmbH proved successful.  We have the full story right here.

Rotkappchen-Mumm Sektkellereien, located in Freyburg at the Unstrut in Saxony-Anhalt in Germany, looks back on a long and eventful history of 150 years.

The company, founded in 1856, succeeded in integrating itself in the free market economy after the German reunification. In 1993, five managing employees, together with the Harald Eckes-Chantre family, took over the sparkling wine producer from the trust by means of a management buyout.  By 2001, Rotkäppchen-Mumm Sektkellerein was the market leader in sparkling wines.

Its highly successful marketing strategy made it possible for the company to continuously expand its market share and to become the leading sparkling wine label in the region. Today, the company produces sparkling wines, still wines and spirits at 5 different locations. In Freyburg alone, around 150,000 bottles are filled every day.

To control the wine stabilization process, Rotkäppchen-Mumm uses ILM conductivity meters from NEGELE.

Tartar refers to calcium salt (calcium tartrate) or potassium salt (potassium hydrogen tartrate), both of which can occur through the combination of tartaric acid with calcium or potassium.  While this may be tolerable in still wines as an indicator of a high mineral content, the “wine diamonds” are undesirable in sparkling wines.  Apart from visible quality impairments, the crystals in this case lead to “gushing”, the uncontrolled, profuse overflowing of foam when a bottle is uncorked.  In addition to the concentrations of tartaric acid, potassium and calcium as well as the pH level and the alcohol content, temperature also plays an important role in the crystallization process. The lower the temperature, the lower the solubility – and a lower solubility leads to the precipitation of tartar. Therefore, one of the ways to stabilize wine is to accelerate crystallization through cooling and the addition of tartar crystals, which act as crystal seeds and promote the precipitation of tartar (so-called contact method).

anderson-negele 

Application of cold/contact method at the Rotkäppchen-Mumm Sektkellerei

At the winery, tartar crystals are added to sparkling wine that has been cooled to approx. -1 °C (stabilization temperature) in a reaction tank (contact tartar). These contact crystals combine with the dissolved potassium or calcium salts in the reaction tank at temperatures close to freezing

The conductivity of the unfinished sparkling wine is affected by the presence of tartar. As tartar crystallizes out, the number of free ions in the sparkling wine goes down, reducing its electrical conductivity (measured in millisiemens) until no more crystals are formed

The conductivity in the reaction tanks is continuously monitored with the ITM inductive conductivity meters from ANDERSON-NEGELE via a bypass.  Once the crystallization process is completed, the conductivity stops dropping and the sparkling wine is “wine stabilized”. Experience has shown that this process takes 3-4 hours.  Subsequently, the (heavy) crystals are separated from the “tartar stabilized” sparkling wine using a Venturi centrifuge (hydrocyclone) before the sparkling wine is fed to a plate separator for further processing.

The conductivity of the unfinished sparkling wine is a measure of the tartar content and thus a decisive process parameter in meeting the high quality requirements for the products of Rotkappchen-Mumm Sektkellereien GmbH.

We are pleased that RotkäppchenMumm Sektkellereien GmbH trusts in the measuring devices of Anderson-Negele to meet their high quality standards.

 

 

 

 

 

waste water

Quadbeam has the perfect solutions for the Wastewater Industry

What if we could offer you self-compensating process control sensors, which gave you much improved control and reliability?  Your current single and dual beam turbidity sensors are great, but once you have tried Quadbeam’s answer, you will never look back.  Quadbeam offers us a range of applications, focused on accuracy and better control of your processes.

In the Waste Water Industry, these are vital elements.

 

Quadbeam promotes these key benefits:

  • Improved process control
  • Reduced costs
  • Long-lasting components
  • Highly repeatable, reliable and accurate
  • Controls de-sludging process

The various Applications where their waste water products can be utilised are:

  • Polymer dosing control for DAF plants
  • MLSS measurement
  • Monitoring influent and overflow streams
  • Return/Waste Activated Sludge
  • Final water release monitoring.
  • Clarifiers

Let’s take a step back and ponder on what wastewater treatment is all about and why it’s so important to have accurate systems in place.

quadbeam waste water

The stages of wastewater treatment:

  • Influent screening to remove plastic and other indigestible solids
  • Separating heavier particles from the liquid in the primary sedimentation tank – heavier particles sink to the bottom of the tank (the sludge blanket) while the supernatant (surface overflow effluent) rises to top
  • The sludge must be emptied at regular intervals to make room for more de-sludging process
  • A sludge pump can prove useless – either it allows overflow or will pump out water with the sludge
  • Knowing the level of the sludge blanket is paramount for controlling the de-sludging process

This is where Quadbeam comes in …

  • One can control the de-sludging process by:
  • Either using Quadbeam’s MXD73, MXD75 or MSSD20 transmitters with Series 20 sensors
  • Using two of these – reason being that with a single sensor installation, you run the risk of too much sludge being discharged and the sludge blanket will be lost
  • Using two Series 20 sensors, they rally with one another to ensure the blanket is always maintained
  • Further factors which affect the sludge blanket formation
  • Settling rate
  • Influent rate
  • Wastewater source and components
  • Downstream solids concentration requirements
  • Blanket height vs solids concentration correlation

Other areas which must be taken into account are:

  • Whether the sludge blanket is to be used for thickening (generally underflow solids concentration can be 0,5% to 1,5%) or
  • Or, to be used for digesting (2,0% to 5,0% solids)

These factors are relevant for the primary clarifier process.

As the influent to a primary clarifier is raw or screened wastewater mixed with recycled effluents from the plant, it is important to check.  Check that your influent flows are not extreme and causing disruptions in the sludge blanket accumulation.

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.
