Flow Switch

This system consists of a sensor probe mounted in a pneumatic pipeline, gravity chute or feeder and a control console mounted in an area accessible to users. The Remote / Integral unit is a high quality, industrial grade instrument that senses flow / no-flow conditions using non intrusive Doppler technology (microwave) to provide highly reliable and sensitive motion detection. It works by transmitting a low energy signal through a Teflon process seal into the material flow stream. A portion of the signal is reflected back to the sensor, with the movement of material causing a frequency shift – called the Doppler shift – which is used by the sensor to detect material flow. Both remote and integral versions are available and the typical application consists of Flow detection in Pneumatic Conveying Pipelines, Over Conveyor belts and other Solid Flow Pipelines.
