Delta Controls - Model 622 - Directly Inserted Flow Switch - Datasheet

The Delta Controls Model 622 Flow Switch produces on/off switching action in response to liquid or gas flow through horizontal or vertical pipelines and ducts. The general purpose is to detect loss of adequate flow or to alarm of excessive flow thus protecting pumps, blowers, heat exchangers, etc. The paddle extends into the flowing stream and operates an output switch at the setpoint flow rate.
