When purged with compressed air, liquid within a downpipe extending into the tank is displaced by air pressure equal to the hydrostatic force created by liquid depth. If carefully regulated at a low rate of flow, air pressure will constantly maintain equilibrium against the force of the liquid. Output is proportional to liquid depth and can be transmitted as an electronic 4-20 mA signal or pneumatically as a direct 1:1 pressure signal.
