Surface mining Solution for flow measurement in gold ore processing plant sector

Application: Stainless steel pipe DN 500. Partial filling with heavy fluctuation. Acidified, very turbid water (approx. 50 NTU).

  • Replacement of a non-functioning clamp-on measurement
  • Continuous flow measurement to control a processing plant for acidified water
  • Reliable measurement at fluctuating level, variable turbidity and acid contents

  • The cross correlation method with digital pattern detection has been used. Here the pollution load does not affect the velocity evaluation.
  • The corrosion-proof pipe sensor Type POA was installed directly from the outside using a welding nozzle bottom upwards flush with the channel bottom. The sensor provides readings on level and flow velocity directly to the transmitter.
  • The transmitter computes the current flow rate and transmits the data via ModBus to the processing plant control system.

  • Easy and uncomplicated retrofitting without dismantling works on existing pipeline
  • Reliable and failure-free measurement, even under heavily fluctuating intake conditions
  • Quick and easy installation and commissioning
  • Programming and commissioning in the national language
