OMEGA’s PX77 Series differential pressure transmitter is a unique device designed to measure depth of liquid in a pressurized tank. This unit is mounted on the bottom of the tank with the side port either vented to the atmosphere on a vented tank, or connected to the top of the tank for a closed or pressurized tank.
