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.
