The paddle velocity detection device is designed to monitor the fluid flow in a pipeline and register any anomalous increases, generally caused by breakage of the pipeline itself.
The detector is normally installed in combination with a water flow gate valve, together comprising a safety system.
The detection of the flow rate is achieved with a mechanical system that acts on a hydraulic device without electrical power or any other external energy sources. When a set critical flow rate is reached, the displacement of a paddle lever closes a butterfly valve and interrupts the water supply in the pipeline.
Applications: the detection device is normally installed upstream of pressurized pipelines or in areas at high risk of landslides in order to avoid damage resulting from the incidental rupturing of pipes.

 

The paddle detection system is designed and constructed to operate with fresh water and raw water, on pi-pelines of nominal minimum diameter DN200 and maximum nominal pressure PN40.
Flow rate range: 1.5 to 6 [m/s].
