Micronics UF-DS200 Doppler Flow Switch

The Micronics UF-DS200 Doppler Flow Switch is an ultrasonic sensor. This instrument injects high frequency sound through the pipe wall and into the moving fluid where acoustic pulses are reflected back to the sensor from particles or bubbles in the fluid. It controls flow without any drop in pressure, no sensor fouling and minimal maintenance. Installation takes just a few minutes because there is no need to cut into pipes resulting in a major saving in time and plant outage.


The UF DS200 Flow Switch is housed in a watertight NEMA4X fiberglass enclosure and requires a 115VAC power supply. The flow measurement range is 0.25 to 10 ft/second (0.076 to 3 m/sec).
