The measurement accuracy of an inline, dynamic water cut
measurement is dependent upon many process variables including:
oil dielectric consistency, fluid velocity at the sample point, mounting
geometry and homogeneity of the oil/water emulsion. The values
above represent nominal water cut measurement variances for
a properly installed sensor under consistent measurement point
conditions.
** The smallest water cut step that the instrument can resolve
Load Resistance
