The Flomec QS200 ultrasonic flow sensor is a non-invasive turf irrigation flow meter engineered for reliable leak detection and accurate flow monitoring across 1" to 4" schedules. With no moving parts and LED status indicators, the QS200 gives irrigation professionals fast, low-maintenance visibility into system performance so you can find leaks and blockages before they become costly.

  • Highly sensitive leak detection: Detects flows as low as 0.1 feet per second to reveal leaking valves and hidden system losses.
  • Consistent accuracy: ±2% of reading for dependable measurements across the operating range.
  • Rugged PVC construction: Schedule 80 PVC housing in a PVC tee body with female socket connections for common irrigation piping.
  • Wide pressure and temperature ratings: Rated 150 PSI at 73°F (10 bar at 23°C) and 100 PSI at 140°F (7 bar at 60°C) for typical turf irrigation conditions.
  • Easy installation and integration: Side-by-side (SxS) tee body fits between pipes and works with most common irrigation controllers; LED indicators simplify setup and diagnostics.
  • No moving parts: Ultrasonic sensing reduces wear and maintenance versus mechanical meters.

This product is available in 1", 1-1/2", 2", 3" and 4" sizes (SKU variants QS200-10 through QS200-40). The package includes the sensor body and electronics; installation details, technical specifications, and the full operator manual are provided in the manufacturer documentation. Ideal for landscape contractors, golf course maintenance, and commercial turf applications that require early leak detection and reliable flow measurement.
