Every material has a certain moisture. By knowing that moisture the production, the storage and the quality of this material can be optimized. ACO sensors determine the moisture of different materials in real-time. They are used in silos, conveyer belts, screw conveyers, etc. The moisture sensors are working with the capacity measuring principle. The surface of the sensor is directly in contact with the measured material. The ACO moisture sensors are:

• less affected by contamination, discoloration, particle size and temperature of the material
• designed to cope with the toughest application, longstanding, reliable reading
• adaptable to existing plants with little effort
• up to 16 sensors in 1 system

Aplisens developed flanged diaphragm seals with an inbuilt two channel cleaning system for highly viscous process liquids.

The cleaning medium is supplied to the membrane surface via two channels placed inside the diaphragm seal.

This process prevents the dismounting of the seals from the application process. The seals can be used for Aplisens pressure transmitters.

Aplisens developed a differential pressure transmitter for level measurement in vacuum tanks based on 2 absolute pressure transmitters:

• Modular construction with possibility of replacing of each module of the measuring system
• Output signal 4 ÷ 20 mA + HART
• Accuracy 0,1%
• Intrinsically safe and ex-proof versions

The worldwide growing Anaerobic Digestion (AD) and Biogas sector faces a massive problem while converting organic waste to biogas: Foam. Excess foaming generated in the AD process can reduce gas production by up to 40% and cause huge damages.

Hadro manufactures Magnetic level gauges with

• Reed or Microswitch
• Reedchain transmitter with 4-20 MA analog output
• Field-/Profibus or HART protocol
• Intrinsically safe (Exi) or flame/explosion proof (Exd)

The housing can be made of Aluminum or stainless steel with IP68 and LCD or optical display.

The SmartFoam IMA sensor from Hycontrol, UK is designed to detect and control a wide range of light to dense foams with a single foul-resistant probe. The Suresense+ Controller protects from overflow and blockage, prevents pollution and enables dosing of anti foam agents to reduce cost.

Foam generated in anaerobic digestion can be a costly headache for AD producers and their insurers. In this article Sam Gould, Foam Technology Specialist at level measurement pioneers Hycontrol, discusses the problems uncontrolled foam can cause and how Hycontrol’s SureSense⁺ system can address them.

A multi-point high-accuracy TDR radar level measurement system installed by Hycontrol is playing important safety and logistical roles on the tank farm of a waste processing company in northern England.
