The requirement for good level control of flotation machines is well established and documented. In this article we will focus on the more common level measurement options available in the market in ...

10. Ultrasonic Level Transmitters. Ultrasonic level sensors (see Figure 8) measure the distance between the transducer and the surface, using the time required for an ultrasound pulse to travel from a ...

The LPU-2428 Loop-Powered Ultrasonic Level Sensors obtain all operating power from the 4-to- 20-mA process loop. An internal microprocessor performs volume, flow, and totalization calculations ...

Figure 8 shows an ultrasonic level sensor. Figure 8. Ultrasonic level transmitters use the speed of sound to calculate level. Ultrasonic level transmitters are capable of measuring the distance ...

Omega introduces its new LVCN210 series of ultrasonic level transmitter and controller which provides continuous level measurement up to 3 m (9.8’) with a 4 to 20 mA signal output, and is configured ...

All level control loops consist of essentially three ... The loop powered current signal which works on ... An ultrasonic level measurement alone cannot be used as the froth absorbs the ...
