Principle of Operation
The ST2 uses two small ultrasonic sensors bonded or clamped to the outside walls of the vessel - one on the bottom of the vessel and the
other on the side, to compensate for variations in sonic velocity and temperature. Signals from the transducers are fed into the processor and
displayed locally and/or output to the plant control system. The system calculates the height and volume of the liquid in the tank from the time
taken for the signal to be received from the liquid surface.
