OPUS Series

The process adaptation of OPUS to vessels or to large pipes is simple and typically uses a 100 mm adapter-flange (AF). For smaller pipes or bypass-lines, specific process adapters are available: e.g., flow-through (FT) or bypass (BP). The sensor may be positioned in a standby rack.

Sensor Type Installation Flow rate Analysis volume
OPUS-FT Flowthrough adapter in pipes DN10 to DN25 up to 2,000 l/h 10-1,000 l/h
OPUS-BP Bypass adapter in pipes DN50 to DN200 up to 10,000 l/h 10-1,000 l/h
OPUS-AF Flange adapter in pipes >200 mm or in vessels >10,000 l/h 10-1,000 l/h
OPUS-MPX Multiplexer at up to 4 production lines >20,000 l/h 10-1,000 l/h

Instead of electromagnetic waves (light), ultrasonic extinction applies low energetic sound waves. These waves are passing through a suspension or emulsion with 31 varying frequencies. For the introduction as well as the detection of sound waves, a piezo-electric RF-generator and detector set-up is used. The recorded loss of sound energy depends on the size and concentration of particles. A corresponding attenuation spectrum is determined and converted into a particle size distribution of 31 classes.

Using sound instead of light waves, ultrasonic extinction is independent of the level of transparency. Hence, totally opaque materials like ore slurries, water in crude oil or coke slurries, can be analysed. Furthermore, paints, sugar pastes, or pharmaceutical suspensions with high solids contents, rank as standard applications for the ultrasonic extinction principle.

In addition, the ultrasonic extinction method allows a rugged and robust probe design that resists typical process conditions. The OPUS probe masters temperatures up to 120°C, pressures up to 40 bar, the entire range of pH-value. It is resistant to aggressive media and abrasive materials. For applications in hazardous atmospheres, an ATEX compliant OPUS version is available.

The control and evaluation software provides calculation and display of all relevant and characteristic size distribution values. The OPUS system is fully compliant with FDA requirements and 21 CFR Rule 11. Adaptation to process control systems is natively supported by TCP/IP, Profibus, Modbus, digital or analogue PLC signals.

Ultrasonic extinction analyser NIMBUS für the determination of particle size distribution and concentration in suspensions, slurries and emulsions

The lab instrument NIMBUS analyses manual samples from 300 ml to 1,000 ml in an easy and comfortable way. The compact system uses the OPUS-technology and consists of identical core components. Therefore the same measuring range from below 0.1 µm to 3,000 µm applies to the instrument. Lab applications are found e.g., in petroleum engineering during the analysis of oil sands or in anode production for aluminium smelting (characterisation of anode grade coke in liquid pitch).
