Product 3D Image Get couponsSN51B series electronic turbine flow sensor is another intelligent flow It is a sophisticated flow sensor with small size and easy setting. Built-in intelligent circuit, can set the upper and lower limit alarm values of traffic at will, and can be monitored remotely The flow condition is set at any time, and the turbine measurement medium passes through the flow After processing through sensor intelligent circuit, arbitrarily program.
Protection level: 1P65
- Suitable for measuring low viscosity media such as water, diesel, gasoline.
- Add the upper and lower limit alarm function on the basis of traditional turbine flowmeters.
