The electronic turbine flow switch is an intelligent flow switch and a compact flow sensor. It has the advantages of small size and easy setting. It has a built-in intelligent circuit and can set the upper and lower limit alarm values of the flow rate at will. It can remotely monitor the real-time flow status. All parameters can be set arbitrarily on site. The turbine measurement medium passes through the flow sensor intelligent circuit and is programmed arbitrarily.
It can be customized with explosion-proof type and integrated flow and temperature. The output type can be selected as switch quantity, analog quantity, and pulse.
Features
- Digital display of instantaneous flow and cumulative flow.
- Protection level: IP65,IP67
- Suitable for measuring low viscosity media such as water, diesel, and gasoline.
- Add upper and lower limit alarm functions on the basis of traditional turbine flowmeters.
- Application industries are widely used in industrial automation, petroleum, chemical industry, metallurgy, scientific research, etc.
