RS-900w Polymer Ultrasonic Flow Sensor

With a simple design, the RS-900w Polymer Ultrasonic flow sensor is well suited as a long-term replacement for mechanical impeller meters in cold water applications. By using ultrasonic technology to measure flow, the RS-900w flow sensor measures a wider range of flow rates without any moving parts that wear and require replacement.

Variable Flows. Simple Installation. 

By using ultrasonic technology, the RS-900w sensor can more accurately read flow over a wider range than mechanical impeller meters, which are traditionally used in irrigation.    

  • Wide Flow Range. Measuring low and high flows, these sensors capture variable flows of mixed-zone irrigation systems and seasonal variations.
  • Robust Design.  No moving parts to wear, fully potted electronics and 200 psi (13.7 bar) maximum pressure rating prolongs the sensor life. 
  • Zero Straight Run. Maintains performance when installed next to the master valve or near pipe elbows.
