Capacitance meter measures water in oil with high accuracy
The density or API gravity of crude petroleum varies due to many factors, including temperature, material changes and region or formation from which it is extracted. Those changes can cause standard monitors to mistakenly attribute changes in density to changes in water content, if not properly accounted for. The Universal IV Density Compensated Water Cut Monitor with Multi-Cal Density Compensation (photo) automatically compensates for density changes that may occur in the composition of products, and reduces the calibration requirements due to those changes. Its updated firmware allows for up to 10 different density calibration points. This reduces recalibration requirements and ensures maximum accuracy from load to load, says the company. The Universal IV CM is said to offer the industry’s highest pressure and temperature capabilities (1,500 psi and temperatures up to 450°F), as well as field-proven Cote-Shield technology, which is said to make it impervious to coating buildup on the probe. — Ametek Drexelbrook, Horsham, Pa.
