RF Pickup Signal Processor Applications:

Applications of RF pickup signal conditioners include remote mounting from the sensor allowing for signal detection in areas beyond the temperature limitations of the electronics in a signal conditioner. Also used with turbine meter flow sensor installations where sensing of low flow, near zero velocity with no magnetic drag from the speed sensor is needed.

The principle advantage of RF flow sensors are their ability to detect targets through a substantial non-magnetic metal wall without exerting any magnetic braking effect. This allows, for example, turbine meter rotors to spin freely, providing a wider frequency range to be covered when compared with other types of flow sensors.
