All,

I have installed a Victron Ekrano onboard to measure also my tank volume a little better.

Already changed the diesel sensor for a Wema and just ordered the watersensor.

The original installed sensor is only 25cm long, while the tank is 33 cm deep. Apart from that, I had difficulties reading the led lights.

The sensor in the watertank is screwed in the tank and not a "VDO connection" type.

For the watertank I just bought a S5 WEMA tanksensor, hoping it will fit in the existing hole and I can mount it with nuts and bolts.

Did anybody already updated it to S5 sensors with VDO connection?

Mon analyse du capteur de carburant diesel : le fond du réservoir est incliné.

de sorte que les mesures des LED ne sont pas très fiables ;

même lorsque le réservoir est à moitié plein, les LED indiquent qu'il est plein ;

Ouvrez la trappe à carburant et vous verrez par vous-même.

Donc, si la jauge n'est que de 25 cm, il s'agit peut-être d'une marge de sécurité.

Thanks for your response tango, indeed the led measurement is not working too well.

The question is: Did anybody install a S5 (WEMA) sensor in the watertank of a 2006 Hanse 370?
