FGS-EX Explosion-proof Flow Switch
Intrinsically safe explosion-proof thermal conductivity flow switches are widely used in petrochemical, electric power, metallurgy, steel mills, papermaking, food processing, water treatment, battery factories and other industries.

FGS-EX explosion-proof flow switch features:
1. Intrinsically safe explosion-proof type.
2. Effectively prevent entanglement.
3. It is suitable for a large range of pipe diameters, and the set point can be adjusted arbitrarily.
4. High pressure type, can withstand pressure *0MPa.
5. The indicator light directly displays the flow change.
