Non-Contact Transmitter penetrates froth to measure pulp height.
November 16, 2010 -
Designed to optimize flotation cells, non-intrusive Acoustic Wave Transmitter is mounted above froth and pulp height, so it has no maintenance or mechanical problems. Unit can be supplied ready for connection to typical 2-wire loop power supply used for displacement float transmitter that it is replacing. Available as option, non-intrusive transmitter can continuously measure froth height, which allows flotation cell to maintain constant overflowing of froth to launder.

Hawk Measurement Develops a Non-Contact Transmitter to Penetrate Froth and Measure Pulp Height
Hawk Measurement, a leading global provider of level, positioning and flow measurement technology, has introduced the new acoustic wave transmitter for optimizing flotation cells.
Hawk has developed a very low frequency "Acoustic Wave Transmitter" that is non-intrusive and will penetrate through the froth to measure the pulp height. The Hawk sensor is mounted above the froth and pulp height, so it has no maintenance or mechanical problems. Typically the transmitter can be mounted at walkway height for easy serviceability. The low frequency level transmitter can be supplied ready for connection to the typical 2 wire loop power supply used for the displacement float transmitter which it is replacing. Remote mounted transmitters are also an option.
Hawk also provides as an option, a non-intrusive transmitter to measure the froth height. Continuous measurement of the froth height, provided as feedback to the control loop for the inlet 'Dart Valve', allows a floatation cell to maintain constant overflowing of froth to the launder, even when the ore body type may produce variations to frothing consistency.
