Flomec QS200 Ultrasonic Insertion Flow Sensor - Insert Only

The Flomec QS200 insertion ultrasonic flow sensor delivers reliable low-flow detection and cumulative flow measurement for commercial irrigation, sub-metering and landscape applications. The insert-only sensor installs into a PVC tee or as a retrofit to replace paddlewheel meters, giving precise monitoring where low flows and leak detection matter.

• Flow range: 0.03–4.57 m/s (0.1–15 fps) for extended leak detection and precise measurement.
• Accuracy: ±2.0% of reading for consistent, repeatable flow and totalized measurements.
• Robust construction: PPS (Ryton) body, PEI (Ultem) sensor element and EPDM O-ring for corrosion resistance and long life.
• Outputs & wiring: simple two-wire connector; 36" (914 mm) 18 AWG direct-burial leads; output frequency 0–100 Hz for controller compatibility.
• Power & indicators: operates on 7.5–36 V DC with low quiescent current and LED indicators for power and pulse status.
• Sizes & installation: available for 1"–4" pipe sizes; compatible with common irrigation controllers and offered as insert or PVC-tee mounted unit.

With no moving parts and low maintenance needs, the QS200 is engineered for long-term stability, high-resolution measurement and reliable leak detection in clean water irrigation systems. Documentation and wiring guides are available for easy installation and controller integration.
