1, please use horizontal installation, flow direction please follow the instructions meter 2, in order to avoid impurities caused by water flow switch malfunction, flow switch, it is recommended to install filters at the inlet end 3, using the maximum temperature does not exceed 95 ℃, thermal flow switching applications, so as to avoid a magnetic core out of the thermal type flow controller comprising two resistors in principle closed probes, one of which is heated as a detection resistor, and the other is called the reference resistor is not heated, Prices thermal flow switch, flow of the street, the heat flow switch electronic price, the heating medium is taken away, the resistance value is changed, the difference between the two resistors are used as the basis for determination flow rates. Withstanding pressure: 0 ~ 100bar (high voltage to be customized); medium temperature: -20 ℃ ~ 80 ℃ (medium temperature ≤4 ℃ / s) Ambient temperature: -20 ℃ ~ 70 ℃; Relative humidity: 5 to 85% of electronic Flow Switch Benefits | Tour En (Online) | flow switch provided by the Beijing Science and Technology Co., Ltd.
