Description

Paddle Flow Switch - Model VH780

Paddle Flow Switch VH780NI is a mechanical device, made by SIKA, that monitors the flow of liquids in pipes by using a paddle to actuate a microswitch when a preset flow rate is reached. It is designed for use in pipes ranging from 1 1/2 to 8 inches in diameter, with a brass or stainless steel body, and features an IP65 protection rating. The ""NI"" in the model number likely signifies that it has a brass body, as some sources mention a brass and stainless steel version,
