The flow switchseries V4 operates automatically to protect equipment and pipelines against damage from reduction or loss of flow.
The scoop universal fits pipes with diameters from 1" 1/2 to 20".

The pallet attracts a magnet inside the metal body of the circuit breaker located on the upper part which actuates a latching switch SPDT.
It is used in a wide range of applications such as chemical treatments, air-conditioning, refrigeration, boilers, heating processes, cooling pipelines, compressors, machinery, conveying fluids, water treatment, fire extinguishers, pumps fuel oil, lubricating oil pipelines, food plants, processes mixing machine.
The maintenance is easy.
The whole eletric group may be removed for inspection or replacement without shutting the pipeline.
