Capacitance Level Switches Provide Reliable Water/Oil Interface Detection

By William Sholette, Level Products Business Manager, Endress+Hauser

There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.
