Varec Hybrid Tank Gauges

Varec Hybrid Tank Gauges combine tank level, temperature, and pressure instrumentation to support both volume-based and mass-based inventory measurement.

Depending on the stored product and measurement requirements, the system may incorporate a radar or servo tank gauge with temperature instrumentation and one or more HART® pressure sensors.

Process Controls Corporation - Varec Hybrid Tank Gauging

Measurement data may be integrated through the 4590 TSM, which performs hybrid calculations at the tank side and transfers information to the control-room system.

Alternatively, FuelsManager® can perform hybrid calculations using measurement data supplied by a radar or servo gauging system and a pressure device.

Key Characteristics

Combines direct level measurement with temperature and hydrostatic pressure inputs
Supports radar- or servo-based level-gauging configurations
Integrates level, temperature, and HART® pressure instrumentation through the 4590 TSM
Uses measured tank data to calculate temperature-compensated volume, mass, and density
Supports tank-side calculations or FuelsManager®-based hybrid calculations
Transfers measured and calculated tank data to the control-room system when configured with the 4590 TSM

Ideal Applications

Combining volume-based and mass-based tank inventory measurements
Calculating product density using measured level and pressure data
Determining temperature-compensated volume and mass
Integrating radar or servo tank gauges with temperature and pressure instrumentation
Performing hybrid calculations at the tank side
Performing centralized hybrid calculations through FuelsManager®
