Flow Switch of Metal Material

Our flow switches are designed to prevent catastrophic failure of the torchand ports in the event of low coolant flow. The typical flow rate are 1 ti 1.50 gallons minute.

At the same time, our level and temperature switches are used in the collant reservoirs, made of plastic or metal tank for holding the torch coolant.
