Hybrid Tank Gauging

Varec's primary hybrid tank gauging solution consists of a level instrument (tank gauge), a temperature sensor and HART® pressure sensor(s) integrated into the 4590 TSM. The level gauge selected depends on the product application at hand. In the case of light distillates, Varec would recommend a 6000 STG first, followed by a 7200 RTG (or 7500 RTG), combined with a 4532 ATC (or 4539 ATC) based on the requirement for inventory management (or custody transfer, NMi approved) applications. The 4590 TSM is able to provide hybrid calculations at the tank side and transfer of data to the control room.

Alternatively, FuelsManager can replace the tank side device to perform hybrid calculations. In this solution, either a servo gauging system (6000 STG, 453x ATC and pressure device) , or a radar gauging system (7200 RTG, 7500 RTG, 453x ATC, 4590 TSM and pressure device) can be used to supply the required measurement data.

Principle of Meaurement

Hybrid tank gauging combines an accurate level gauge, temperature sensor(s) and pressure transmitter(s). By utilizing the best of both level based and mass based systems, hybrid tank gauging obtains level, temperature compensated volumes, mass and density measurements.
