The Doppler Flow Meter can monitor the flow rate of dirty or aerated liquids that would damage regular in-ine flow meters such as; wastewater, chemicals, acids, slurries, abrasives and viscous liquids. The ultrasonic sensor of the dopper flow meter is mounted on the outside of the pipe where an ultrasonic signal is reflected back to the sensor from moving particles or gas bubbles suspended in the fluid. The pipe can range from 12.5mm (1/2") inside diameter or greater.
The Doppler Flow Meter includes an isolated 4-20mA to transmit flow rates to remote displays, recorded or controllers. The programmable relays can be used for flow control, pump protection or flow proportionate pulse.
