The Valcom T7B can be used in all industry branches for continuous measurement of specific gravity, level and interface of liquids in open or closed tanks. The T7B allows to realize a reliable measuring system easy to install since no additional components are required because of the adopted construction solutions. The Valcom T7B offers very high reliability and robustness within a wide pressure and temperature range.
