This paper discusses the utilization of microprocessors for level measurements in multiple sealed oil and water tank batteries that incorporate Vapor Recovery Units which cause pressure variations inside each tank. The application consists of the integration of two highly accurate pressure (level) transmitters, one low range vapor pressure transmitter, a microprocessor that utilizes specific gravity information and subtraction techniques, resulting in a highly accurate level measurement system for production stock tanks.
