Kofloc Model RK1970/RK1975/RK1976 Reed Switch Flowmeters(for Alarm Switches)

Kofloc Model RK1970/RK1975/RK1976 Reed Switch Flowmeters(for Alarm Switches) these compact reed switch flowmeters developed centering the focus on cost reduction are for monitoring gas and liquid flows. Any of these models is optimum for the process control of cooling water.

The flow meter (area type flow meter) has a float inside a conical cylinder (tapered tube) with the upper end larger than the lower end. The float moves up and down according to the intensity of flow, and the reading is taken when the float balances indicate the flow rate. KOFLOC provides flow meters with a valve that can perform both measurement and control of the flow rate, flow meters with an alarm function, and many other products.
