In horizontal shell boilers, the water level rises with increasing load (due to the presence of more steam being below the water level in the boiler). As it does so, the water surface area (steam release area) will decrease because, as the water level is above the centre line of the boiler

Two approaches are explained here with mathematical interpretation. (a) Zero Suppression: In some cases, the level transmitter has to be mounted X meters below the base of an open tank as shown in figure 2.
Get A QuoteAs the name suggests, a level measurement transmitter is an instrument providing continuous level measurement. It can be used to determine the level of liquid or bulk-solid at a particular time. Levels of media such as water, viscous fluids, and fuels, or dry media such as bulk solids and powders can be measured using the transmitter.

Get A QuoteThree-element level control as shown in Figure 11 is the most common boiler drum level control strategy. A feedwater flow loop slave is added to the two-element strategy. Three-element level control linearizes the feedwater flow with respect to the steam flow and the level controller output.

Get A QuoteThe purpose of this instrument is to compare the level transmitter's signal against a setpoint value entered by a human operator representing the desired water level in the steam drum. The controller then generates an output signal telling the control valve to either introduce more or less water into the boiler to maintain the steam drum
