High precision servo tank gauge measurement for liquid level, interface and density

The intelligent servo tank gauge  is designed for high accuracy liquid level measurement in custody transfer and inventory control applications. It fulfills the exact demands of tank inventory management and loss control and is optimized in regards of total cost saving and safe operation.


Servo tank gauge measures two clear interface levels and specific gravity of up to three liquid phases.

Profiling of Iiquid density throughout the tank (tank profile) and upper layer (I/F profile).

SIL2 certified alarm output (min., max. and range).

Wetted parts are completely separated from the electronic circuit.

Tank top mounting with 3″ flange weighing only 12kg (aluminum version).

Wide range of output signals including V1, RS 485 Modbus, WM550, M/S, Enraf BPM and HART protocol.

Suitable for atmospheric and high pressure applications up to 25bar.

Field of application:

Servo tank gauge for measurement of: Oil (crude, light, fuel, edible), LPG/LNG, petrochemicals, chemicals, water /chemical interface measurement, foods, liquid food.
