Greetings all:

I'd like hear everyone's personal experience regarding the measurement of water in both hydrocarbon and synthetic oils.

I've been told that Karl Fisher titrations are good, but require far too much labor, and that various automated measurement techniques (capacitive, IR, etc) are inaccurate and are often skewed by changes in temperature.

Comments?

In crude Processing plants, oil/gas separators
use water level tansmitters, just to drain out water without losing any crude.

This type of interface transmitters are available
in Fisher control( Displacer type LTs. This torque
tube is your service dependent)

The calibration is simple. Fill it completely with lighter medium (in our case crude ). The zero
is set and with water (in our case seawater)and
set the span. After filling up with lighter medium
and pump with water and see the interface level
versus output for all the values from 0 to 100%.
