The QS200 Insertion Ultrasonic Flowmeter provides an accurate reading of liquid flow rate and accumulated flow. Designed to support commercial irrigation applications, the QS200 is available in five pipe sizes, ranging from 1 to 4 inches, and is available with a PVC tee or "insert retrofit" for replacement of existing paddlewheel flow sensors. The QS200's patented Transit Time Technology means there are no moving parts to wear out and low maintenance. Long-term stability and a high-resolution measurement range make it possible not only to measure water usage but also to monitor leak detection across your irrigation system.
