Summary

Level measurement can be determined using a pressure transmitter, which utilizes the relationship between liquid level and "head" pressure, known as hydrostatic head pressure. The pressure at the bottom of an open tank or body of liquid is related to the height of the liquid, with 27.679 inches of water column equivalent to 1 PSI at 40º C. Specific gravity must also be considered, as it affects the hydrostatic head pressure, with the formula P=SG • H, where P is the hydrostatic head pressure, SG is the specific gravity, and H is the height of the liquid. Installation types include open tank, pond, or weir level measurement, with various options such as pipe mount, submersible, screw on, flange mount, and flush mount configurations. In pressurized tanks, the total head pressure is the sum of the hydrostatic head pressure and the pressure of the gas blanket, and a differential pressure transmitter can be used to accurately measure the level by subtracting the gas blanket pressure from the total pressure.
