The FLOMEC QS200 Ultrasonic turf irrigation flow sensor is available with a PVC tee or as an “insert retrofit” for replacement of existing paddlewheel flow sensors. Designed for above and below grade applications, such as turf, irrigation, municipal and underground monitoring where the flow rates are between 0.1 to 15 fps (0.03 to 4.6 m/s) and temperatures are below 140° F (60° C). In addition to its low-flow capabilities, ultrasonic technology means no moving parts to wear out or fail when winterizing systems using compressed air. Schedule 80 PVC tee fits five pipe sizes up to 4 inches.
