The LevelMaster combines the industry’s most innovative hardware and software to address the unique custody-measurement and operational needs of tank-level management. The LevelMaster provides not only an accurate level gauge, but also an accurate measurement of the oil and water interface.
Unlike other level-sensing technologies, LevelMaster provides precise levels without having to continuously adjust for changes in the unpredictable properties of storage-tank liquids. LevelMaster floats can measure oil, water, and emulsion levels up to 25 feet (7.6 m) deep, with a standard relative accuracy of 0.1 inch (2.5 mm) or optional high-precision relative accuracy of 0.05 inch (1.25 mm).

Measuring the LevelMaster’s importance
The LevelMaster provides high-precision level measurement for any tank up to 25 feet (7.6 m) tall. A LevelMaster of any length is an exceptional tool that can be relied on to:
Ensure Accurate Sales. For custody transfer applications, the measurement reliability, life cycle, and no-drift accuracy of LevelMaster sensors are unsurpassed by competing technologies. When used with powerful XSeries technology, the LevelMaster is approved by the Bureau of Land Management for measuring gross volumes of oil in custody-transfer transactions.
