· Range: 1cm/s~150cm/s (water), · 3cm/s~300cm/s(oil) · Temperature Compensation LED Indicator Used For Power Generation, Metallurgy, Steel, Paper, Boilers MFM500A Flow Switch is an intelligent flow monitoring sensor that does not require frequent adjustment and maintenance. It can play an early warning and protection role when there is a traffic failure on key equipment. The switch is based on the principle of thermal diffusion and uses an ARM processing core. Different installation interfaces can be selected to meet various pipe diameter requirements. It is suitable for a variety of application environments, such as real-time monitoring of pipeline water flow, flow monitoring of cooling or lubrication systems. Even in the case of changing temperature, the flow switch of Micro Sensor can guarantee the accuracy of measurement.
