Flow Sensor 1/4 inch
Magnetic flow sensors operate on the principle that the movement of a conductor through a magnetic field provides a voltage. Flow Sensor 1/4 inch, They consist of a flow tube that generates the magnetic field in the pipeline, and an electronic converter that measures induced voltage.
Main Containt :
This 1/4 inch water flow sensor is basically a small turbine whose output signal is a series of digital pulses. The frequency of the pulses is proportional to the flow rate of the liquid passing through the sensor. That digital signal, whose frequency is in the range between 0Hz and 100Hz, can be read directly through one of the digital
This flow sensor is mainly used for accurate flow measurement. It may be installed in the hot water inlet end for detecting water flow.
When water through the flow rotor assembly, the magnetic rotor will rotate and the Speed of a rotor will change as the flow change.
Hall current sensor Read the pulses and provide output corresponding pulse signal and feedback sent to the controller.
then the controller will measure the flow and display the value in terms of flow speed and total volume passed through the sensor.
these sensors may be used for water heaters, credit card machines, water vending machines, flow measurement devices.
