Product Description

Micro Hall Liquid Flow Sensor for Water Heater 


Operating principle

 As liquid passes through the flow sensor body, the magnetic rotor spins at a rate proportional to flow. This Causes a series of magnetic fields (the rotor vanes) to excite the Hall Effect sensor, producing a series of voltage pulses

Specifications
Electronic water flow sensor  
1.Low cost 
2.Long life 
3.Simple installation 
4.Wide applications

Introduction
Flow switch consists of magnetic core, rotating impeller, external casing and reed switch. Flow through the sensor activates the magnetic core to trigger switch action, with signal output.

  Withstand hydraulic pressure  ≤0.35Mpa 
  Voltage rating  DC5V-24V   
  Insulation resistance  >100MΩ
  Precision  0.2-6 L/min ±10%                                          2-30  L/min ±10%                                          1-60  L/min ±10%
  Flow pulse  F=(18Q)+5% , Q=L/min
  Output pulse duty cycle   50%±10%   
  Max output pulse voltage  >DC4.7V   
  Min output pulse voltage  <DC0.5V 
  Body material  nylon

Features
* Imported components of the magnetic switch
* Simple working principle
* Highly reliable
* Easy to install
* No standby power requirements
* Cheap costs
Applications

It is used in the control of water circulation, water charging and discharging, water heating, water pump switch on and off of solenoid valve, or powering on and off of water discharging for electric water heater, solar energy water heater, air condition and other water systems.
