DESCRIPTION

The Model WCM 7300 is designed to provide the highest possible sensitivity, resolution, and accuracy for water content determination in crude oil, other hydrocarbons, or other low dielectric liquids from a max of 25% to levels below 1000 parts per million (ppm). In oil and natural gas (condensate) production, water cut and S&W measurements are significantly improved with the WCM 7300 technology. Enhanced digital signal processing and full product temperature compensation are two of the technological advancements utilized by this device. Probe sizes from 2” through 12” are available. 4-20 mA and 0-5 volt outputs are available for remote readout. Water cut, process temperature or probe electrical value can be selected for viewing without removing condulet cover by use of a supplied magnet to operate an internal reed switch.

Specifications

Power Supply	20-30 Vdc +/-10% @ nominal, 100 mA max.
S&W Full Scale Range	0-25% Field adjustable to 0-5%, 0-10%, etc.
Accuracy	Is defined as the variance observed between the 7300 reading and the water grindout of the oil. Normal variances are: +/-.05 from 0 to 5% water +/-.1 from 5 to 10% water +/-.15 from 10% to 15% water +/-.2 to .25 from 15 to 25% water
Displays	One line 16 character, alphanumeric LCD showing by selection: Water Cut Process Temperature Probe Electrical Value Red/Green LED showing good oil, bad oil, or by passing, condition.

PRODUCT TEMP. COMPENSATION

The base dielectric constant (Dk) of oils can change with changes in temperature. This can cause traditional monitors to change without a variance in water content. For example; for a 10°F change, a typical crude oil may show a reading shift of as much as 0.1%, which normally would be considered as water. The WCM 7300 measures product temperature and calculates a corrected cut reading, providing a true water or S&W cut at any temperature up to 160°F.

APPLICATIONS

LACT (Lease Automatic Custody Transfer) Units
Detect and reroute oil that has been contaminated by excess S&W.

Pipeline Loading
Monitor transfer of petroleum/condensate products from offshore loading facilities.

Dehydration Equipment
Determine and enhance equipment efficiencies.

Fuel Oil Monitoring
Determine contamination of fuel oil by condensation or other external factors before entry to engine.

Storage and Treating Facilities
Monitoring and early detection of undesirable conditions as well as interface detection during de-watering of storage tanks.
