QS100 Turf Irrigation Flow Sensor


QS100 K-Factors

The FLOMEC® QS100 Ultrasonic Turf Irrigation Flow Sensor has NO moving parts and NO flow restrictions, making it nearly INDESTRUCTIBLE.


It’s SO ACCURATE it senses a dripping faucet. The QS100 measures water flow rates 5X LOWER than competing flow sensors. It literally senses leaky valves, blockages, and other problems.

This 1-inch flow sensor is not only economically priced but is also excellent for commercial and residential irrigation flow detection and measurement of small leaks and line breaks.

The ability to detect flows down to 0.22 GPM makes it ideal for low-flow drip zones. In addition to its low-flow capabilities, ultra-sonic technology means no moving parts to wear out or fail when winterizing systems using compressed air.
