The MW50 series flow switch features a robust and reliable structure with accurate and stable performance. It is primarily used for flow monitoring and control in pipelines, as well as in the cooling and lubrication systems of various large, medium, and small-sized equipment. When the flow exceeds the preset switching point, it can output a control signal. This preset switching point can be set at any position within the range and can be conveniently adjusted after installation.
- Simple and reliable structure, robust and durable;
- Magnetic coupling measurement system;
- Arbitrary installation direction;
- Wide measurement range;
- Multiple material options;
- Clear graduated scale and rotating pointer for easy reading;
- Adjustable preset switching point;
- High-power built-in relay;
- Explosion-proof.
