Tank level sensor for ships API Marine
TGD

Tank Gauging Device
The API TGD (Tank Gauging Device) is a multi-functional device, which measures a cargo tank’s level and pressure as well as temperature and density of the cargo. It is based on patented principle of Guided Low Frequency GLF™ wave propagation, which allows equal precise accuracy of measurement along tank height in any shape of tank. The tank gauging device has been developed to work with the highest level of accuracy in any type of liquid, oil products, liquefied gases, acids, solvents and other chemicals preventing any waste without influence of foam from surface.

The data from the API TGD is transferred to the control room through just two cables, thus reducing the cost of lengthy cabling throughout the tanker. The tank gauging device has four integrated measuring channels:

- Low frequency non contact level gauge with accuracy of 2 mm
- Multiple thermo sensors for temperature profile measurement in the tank
- Density sensors
- Inert Gas Pressure sensor
