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.

Frequently Asked Questions

What pipe sizes does the QS200 support?
The QS200 is available for 1" to 4" pipe sizes and sold as an insert or PVC-tee mounted unit for simple installation.
Is the QS200 suitable for dirty or fuel-containing fluids?
The QS200 is intended for clean water; it tolerates limited solids but is not recommended for fuels (EPDM seals resistances are limited).
What power and wiring does the insert require?
Insert sensors use a simple two-wire connector, 36" 18 AWG direct-burial leads and operate on 7.5–36 V DC with low quiescent current.
How accurate is the QS200 and can it detect leaks?
The QS200 provides ±2.0% reading accuracy and extended leak detection down to approximately 0.03 m/s (0.1 fps), ideal for irrigation monitoring.
