YF-DN40 1.5 inch is a plastic body water flow sensor that contains a water rotor and a hall-effect sensor and is used for flow measurement for industrial applications. When the water flows through the rotor, the rotor rolls, and its speed changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. The output of the flow sensor is proportional to the water flow. The more the water flowing more are the pulses.


  1. Accuracy in 1 ~ 120L / MIN  ± 2% inline
  2. Flow pulse characteristics F = (0.45 * Q) Q = L / Min meet
  3. Low-temperature test at -20’C temperature placed after 72h, at room temperature for 1h, the first measurement accuracy within ± 5% value inline
  4. High-temperature test temperature at 85’C placed after 72h, at room temperature for 1h, the first measurement accuracy within ± 5% value
  5. 11/2″ DN40 flow rate 5~150L/min  Plastic Hall Turbine flow sensor meter  switch valve control liquid flow sensor
