RF Admittance Level Transmitter utilizes the capacitance formed between the sensing probe and the reference probe or the metal vessel wall to calculate the level of the medium inside the vessel according to the capacitance theory that the capacitance and vessel are proportional increased. 

When the probe is surrounding by the air, little capacitance (CA) is measured by the equivalent capacitor, the capacitance increase gradually as computing media, the max. capacitance (CB ) will be measured while the tank is full, the difference (dC) between CA and CB is proportional to the level (Recommend range dC = 25 ~ 2000 pF).
Features
