High Precision DN15 G1/2 Water Flow Sensor Hall Effect

Description:

Water flow sensor is mainly composed of plastic valve, water rotor subassembly and hall sensor.It is mounted on water heater inlet and used to meter water flow. When water goes through rotor subassembly, magnetic rotor rotates and rotating speed changes with the flow. Hall sensor outputs corresponding pulse signal as feedback to controller and controller judges water flow amount and adjusts flow.

Features:

• 
  This flow sensor meter is lightweight, small and easy to install.
  
• 
  The internal impeller has stainless steel shaft which is quite wear-resistant.
  
• 
  Seal ring uses mechanical structure that stressed from up and down directions and will not leak.
  
• 
  The sensor has high quality Hall effect element and is encapsulated with glue, preventing from water entering.
  
• 
  It is a great sensor of high precision, long service life and stable performance.
