Capacitance Level Meters

Capacitance Level Meter is the use of the capacitance change to measure the container medium level measuring instruments, container, made ​​by the electrodes and the conductive material of the container wall form a capacitor for a given electrode, the measured dielectric permittivity constant, plus a fixed frequency of the measured voltage to the electrodes, current flow through the capacitor depends on the capacitance between the electrodes medium height, and in proportion. capacitor material level gauge is based on the capacitance The change in level measurement, the measured capacitance meter level, a basic requirement: the measured medium relative permittivity in the measurement process should not be changed.
