Principle of Operation

The RFnivo is normally screwed into the lateral container wall at a position, where the material shall be measured. The device can also be mounted from the top of the container. In this case an extension piece is used to mount the probe level with the height to be measured.

The length of the probe can be up to 2.5m (98.4") with rod extension or 20m (787") with rope extension.

The use of a sliding sleeve is recommended so that the switch point can be changed continuously during operation of the device.
