QS200 INSERTION ULTRASONIC FLOWMETER 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, 1 to 4 in. The QS200 ultrasonic insert is available with a PVC tee or as an “insert retrofit” for replacement of existing paddlewheel flow sensors. FEATURES / BENEFITS Low-cost, effective and easy installation No moving mechanical parts (low-maintenance) Simple two-wire connector (for power and pulse) Compatible with irrigation controllers (common name brands) High accuracy: ± 2.0% of reading (compared to full scale accuracy) Provides extended leak detection down to 0.1 fps (0.03 m/s) LED light indicators: (green for power and amber for pulse) Patented design • Agriculture Irrigation • Turf / Landscape Irrigation Systems • Micro Irrigation Systems • Groundwater Monitoring • Ideal for clean water flow measurement • External wiring: (direct burial wire) INSERT DESCRIPTION Designed for above and below grade applications, such as irrigation, municipal and underground monitoring where the flow rates are between 0.1 to 15 fps (0.03 to 4.57 m/s) and temperatures are below 140° F (60° C). QS200 inserts 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. • Sub-Metering Applications: » High Rise Tenant Buildings » Apartment Complex » Universities » Commercial Businesses » Processing Facilities

*K and offset values are used to calculate the frequency of the pulses from the QS200 electronics The formula for frequency is Freq = (GPM/K) - offset ** Offsets listed in this table are expected to be calibrated at the factory and therefore no additional correction should be required. *** Maximum water pressure for larger line sizes would be based on the material of the sensor, adapter, and pipe. Pressure is also derated due to temperature (1.20 psi / °F). 1-INCH Tee Housing 2-INCH TeeHousing Service & Warranty: For technical assistance, warranty replacement or repair contact your FLOMEC® or...
