Tolerance ±15% of full scal
Media Temperature -30~110℃
Average Pressure Loss 0.01bar at Qmax.
Hysteresis depending on switch value, minimum 0.7 l/min.
Metering Substances Oil, Water, Gas, Air (If special substances, please declare)
Max Pressure 25bar (40bar could be custom-made)
Pipe Size DN10~DN80
Materials Brass or Stainless Steel
Good repeatability
Low pressure loss
Dirt resistant
Hermetic separation of electrical and hydraulic components
Stress free fixation of switch unit by plastic cap
WFS21 Paddle Flow Switch is specially designed for the Flow Monitoring of Water Source, Water-Loop Heat Pump Air Conditioning Systems and Heat Pump Water Heater.
Due to the unnecessary loss caused by the abnormal high pressure protection failure or compressor failure, as the Water-Source Heat Pump Systerm meet a sudden disruption of water flows (such as cooling water pumps stop by the accident, the water solenoid valve of air conditioner suddenly shut down, or other sudden water interception). When heating, the heat exchanger frozen because of the sudden water interception
