Another challenge was the ideal mounting position: to minimise splashing and build up on the sensor, it was better situated quite close to the vessel wall – but not an ideal position for a contactless level sensor as the proximity of the wall and any build up will interfere and compromise both performance and accuracy. The unit installed, uses 80 GHz frequency, which means its DN80/3” flange only has a 3 degree beam angle. The result of this is that it handles the situation with ease, the more focused sensor signal beam bypasses the vessel wall and any build up, following the level confidently. VEGA 80Ghz radar possesses some unique performance characteristics, unrivalled 120dB sensitivity, combined with the enhanced focussing and market leading signal processing software means it creates a formidable package. These abilities enable it to cope with challenges like mounting close to vessel edges (through valves or long nozzles), coping with heavy condensation and build up on the sensor face to deliver a reliable measurement, even with a turbulent or agitated process surface.
British Sugar at Newark are very happy with the results from this application, an improved reliability level measurement
, better quality milk of lime and less maintenance time lost working on instruments or clean ups in the lime mixing plant.
