Measuring methods at a glance

MethodSuitable forInstallation
Lever-type sender (TGW, TGT)Water or fuelFrom above through a tank opening
Tank probe (TDS, TDN, TDT)Water and fuelFrom above, length to suit the tank depth
Non-contact ultrasonic (UTV)Black and grey waterFrom above, no contact with the medium
External sensor (Gobius)Tanks that should not be openedOutside on the tank wall

Black water tanks

In black water, mechanical senders clog quickly. Here you measure without contact by ultrasound or from outside through the tank wall. For a simple full warning, a switching sensor is enough.

The display

A single tank can be shown on a round gauge. For several tanks, tank monitors such as TCS or VTM 2 are a good choice. To see battery and tanks together, use the battery and tank monitor BTM2 or the PCU control unit, which accepts up to four tanks directly. The universal tank interface UTI connects existing senders to a new display.

Installation and calibration

Tanks on board are rarely rectangular. For an accurate reading, calibrate the level in several steps: empty, quarter, half, three-quarters and full. This way even a wedge-shaped or moulded tank is displayed correctly.

Frequently asked questions.Short answers.

Which tank sender suits black water tanks?

A non-contact ultrasonic sender or a sensor that measures from outside through the tank wall. Mechanical senders clog quickly in black water tanks.

Can I measure the level without opening the tank?

Yes. Sensors such as Gobius are bonded to the outside of the tank wall and measure through it, without drilling the tank.

How many tanks can one display show?

That depends on the device. Tank monitors show several tanks at once, and up to four tanks can be connected directly to the PCU control unit.

Why is my tank gauge wrong?

Usually the tank is irregularly shaped and the display has not been calibrated. Calibrating in several steps solves this in most cases.
