ORCA Bed Level System

ORCA Bed Level System

The ORCA Sonar Bed Level System will measure up to two density interfaces simultaneously. Typically these are bed levels / RAS blanket and floc / fluff layers. The sonar produces a high power concentrated beam, and provides critical plant control to optimize performance.

Industries

  • Concentrate Thickeners
  • Tailings Thickeners
  • Hi-Rate Thickeners
  • Paste Thickeners
  • Deep Cone Thickeners
  • Water and Wastewater Treatment

Principle of Operation

The ORCA Sonar Bed Level transducer emits a high powered acoustic pulse, which is reflected from the interface density selected. The reflected signal is processed using specially developed software algorithms, that eliminate lighter floating densities and stratified layers, allowing measurement of RAS or BED levels. It can be calibrated to measure lighter densities like FLOC or one of the outputs could be used for a CLARITY output, similar to a basic turbidity transmitter measuring solids in suspension. By choosing the correct sonar transducer frequency, the ORCA sonar guarantees the optimized performance when measuring both light and heavy density interfaces.

  • Dual independent analogue outputs to track two different interfaces, or clarity simultaneously, with the one sonar sensor
  • Easy calibration to track specific density interfaces, eg: floc / fluff layer - 1g/l, Bed 10g/l+
  • Industrial scum cleaning mechanisms, that do not require maintenance
  • No wiper blade assemblies
  • Sewage Plant
  • Tank or Vessel
