Measuring very low flow rates, the RS-900w Polymer Ultrasonic Flow Sensor is well suited for mixed zone irrigation applications: drip, rotors and spray heads. The simple design makes the sensor installation straightforward and cost effective.
- Three sizes with NPT or BSP tapered threads
- Forward flow accuracy ± 2% of reading
- 200 psi (13.8 bar) pressure rating
- Submersible IP 68 with fully potted electronics
- No moving parts to wear
- NSF/ANSI/CAN 61 and 372 certified option
- Same two-wire power/pulse output as impeller flow sensors
- Forward and reverse flow flashing LED indicators

N/A
Managing water usage in irrigation requires reliable flow sensoring. The wider the flow range and more accurate the sensor, the easier it is to detect leaks and respond quickly. As a critical part of water management, the RS-900w flow sensor reads consistently and does not degrade over time due to wear and tear.
