Controlling Boiler Water Levels with a Differential

The working leg pressure constantly changes due to the ever-changing water level inside the vessel. The working leg is piped to the bottom of the vessel height being controlled. The weight of the water inside the vessel at any particular time is then compared against the total possible weight if the vessel were to be full (reference leg).
