RF Capacitance transmitter is a multi-function transmitter that offers the user unparalleled power. It can interface with two separate vessels, while software mathematics allow for the total or difference of the two measurements. As the media rises and falls in the tank, the amount of capacitance change between the probe and the ground reference also rises and falls. The electronics convert this capacitance change into a continuous level measurement. It is suitable for hydrocarbons, solvents, interface and high temperature and pressure liquid applications.
