Industrial instrument sensor
TMR Flow SensorDetailed Description：
Working principle：
The TMR flow sensor is equipped with multiple built-in TMR sensors, which output high and low level pulse signals for flow, and an anti theft sensor is added to replace the mechanical meter type counting sensor, greatly improving the stability and safety of the instrument. The TMR temperature flow sensor also has a built-in temperature sensor with temperature detection function.
