Hydrostatic Level Transmitters, also known as pressure level transmitters, essentially determine a container’s fluid contents by measuring the pressure of the resting body of fluid within it. The bigger the force of the liquid, the bigger the volume of fluid inside the container.
This is one of the most common types of fill level detection devices. It is crucial that the liquid’s density remains constant to ensure accurate measurement. As the liquid’s gravity increases, the pressure per cubic inch exerted on the transmitter also rises.
