  1. The water flow sensor is applied for water heater, imprinter, automatic water machine, and other flow metering equipment.
  2. Portable size and light weight, easy to install
  3. With stainless steel ball inside of the impeller, wear-proof
  4. Up and down structure stress applied for the seal ring, avoid to leak
  5. Imported Hall element, adopt pouring sealant encapsulation to avoid to leak and age


  • When magnetic material is close with the sensor, its characteristics may vary.
  • In order to avoid particle debris, the sensor must be installed after a filter.
  • The flow sensor installation has to avoid strong vibration and shaking of the environment, so as not to affect the sensor's measurement accuracy.
