The measurement of volumetric flow rate of electrically conductive fluids. Basic measurement is
the flow velocity upon which all other measurements are based.
The sensor includes a ceramic liner for high abrasion resistance and capacitive signal pick up for
a lower minimum conductivity of the fluid.
