Designed for commercial and residential irrigation, this inline flow sensor detects small leaks and line breaks, measures flows as low as 0.22 GPM for low-flow drip zones, and uses ultrasonic technology with no moving parts to ensure durability during winterization. In addition, it includes two 36" (914.4 mm) 18 AWG solid copper wire leads with UL Style 116666 direct burial insulation.

The FLOMEC® QS100 Flow Sensor is an economical and easy-touse flow sensor designed for residential and commercial irrigation and sub-metering applications. Utilizing ultrasonic technology, the QS100 provides flow ranges of 0.22-33 GPM. This wide turndown (150:1 turndown ratio) makes it possible to accurately monitor all of your zones from small drips (minimum flow of 0.22 GPM detectable) to large sprayer applications. The meter can also detect small leaks. The QS100 is 100% maintenance-free with no moving parts and won’t be damaged by debris and wintertime blowdowns.
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, ultrasonic technology means no moving parts to wear out or fail when winterizing systems using compressed air. QS100s are supplied with two single conductors, 18 AWG solid copper wire leads that are 36 inches (914.4 mm) in length with UL Style 116666 direct burial insulation.
