Hydrostatic Pressure Measurement the ESI Technology Way…..

What is Hydrostatic pressure and how does ESI’s Hydrostatic level measurement technology work?
What is Hydrostatic pressure?

Hydrostatic pressure is commonly described “The pressure equivalent to that exerted on a surface by a column of water of a given height due to the force of gravity”.  A liquid column above the pressure sensor creates hydrostatic pressure, which is a direct indicator for the liquid level. Generally, the standard unit of measurement is calibrated in metres of water gauge (mWG). This may sometimes be referred to as metres of water column (mWC), or metres of H2O (mH2O). Other countries may use different units of measurement, such as inches of water column (“WC).

How does an ESI Hydrostatic level transmitter work?
The measuring cell of the pressure sensor detects small changes in hydrostatic pressure, which increases or decreases according to the filling level.
