This product is a 2-wire loop powered BS&W water-cut probe which is installed directly into a crude oil piping system. It can also report and detect free water variations in any hydrocarbon e.g gasoline, diesel, naptha. System integrators can find  information on installation, wiring and how it works by referring to the EASZ-1 manual Rev.2.0

Watercut meters measure the H2O content (percentage) of crude oils and similar liquids in a flowing stream. The American Petroleum Institute refers to this as OWD or On-Line Water Determination.

Ideal for applications for first, second and third stage crude oil separators, crude oil transfer in pipelines and in tank truck terminals. The watercut is expressed as a percentage of water in the total fluid stream.
