Hydrostatic pressure is described
as being the pressure exerted by
a fluid at equilibrium to a given
point within the fluid, due to the
force of gravity. A liquid column
above the pressure sensor creates
hydrostatic pressure, which is a
direct indicator of the liquid level.
In Europe the standard unit of
measurement is metres of water
gauge (mWG), also referred to as
metres of water column (mWC),
or metres of H2O (mH2O).
ESI Technology design and
manufacture a range of pressure
transmitters for hydrostatic level
applications. They are available
in a range of diameters and
can be calibrated to any unit of
measurement.
desiccant housing at surface level
is required to prevent moisture
ingress over time. Stilling tubes
and weighted nose cones are also
available.
ESI Technology can quote for
individual sensors or complete
systems to include cable, housing,
display and other accessories.

It is also necessary to use a
special vented cable so that
barometric pressure does not
affect the true hydrostatic
pressure measurement. Also, a
