Bubbler system in open vessel
You can use a bubbler system that has a top-mounted pressure transmitter in open
vessels. This system consists of an air supply, pressure regulator, constant flow meter,
pressure transmitter, and a tube that extends down into the vessel.
Bubble air through the tube at a constant flow rate. The pressure required to maintain flow
equals the liquid's specific gravity multiplied by the vertical height of the liquid above the
tube opening.
