Hallo ans Forum.
Ich habe eine Frage zum Frischwasser Sensor.
Kann mir jemand Daten zum verbauten Sensor nennen.
Ich möchte an meinen Victron Cerbo SX den Tanksensor anschließen. Der Eingang des Cerbo ist 2-polig aber am Sensor sind 5 Adern angeschlossen. Gibt es dafür einen Umbausatz oder Konverter oder weiß jemand wie der Sensor angeschlossen wird.
Vielen Dank
Rolf

I have a question about the fresh water sensor.
Can someone give me some data on the sensor installed?
I would like to connect the tank sensor to my Victron Cerbo SX. The input of the Cerbo is 2-pole but 5 wires are connected to the sensor. Is there a conversion kit or converter for this or does anyone know how the sensor is connected?
Thank you very much
Rolf

Since you appear to be very keen on monitoring items accurately, to me it seems odd that you are thinking of relying on the notorious unreliable, inaccurate, 4 rods in the water tank system.  Many people have switched the sensor.


You can get more ideas my putting in "water tank sensor", "any forums" any date" into the advanced search function.

Thank you Martin & Rene.
Unfortunately, the search function does not work for me.
Hence my question to the other members.

We have now connected the standard diesel tank sensor to a Victron Cerbo-CX instead of the WE-Panel. This works very well. 
Now we would like to replace the water tank sensor. The built-in sensor with a 5-wire cable does not fit. We would therefore like to replace it with a Philippi TGW sensor. Can anyone tell me the sensor length or the water tank depth for a Hanse 385?

Hallo Rolli,

bei der H345 war es 350 mm. Du kannst es einfach durch die Inspektionsluke messen.
Leider gibt es keine Lösung für das Spezialgewinde des miesen Hansesensors. Ich habe deshalb eine weitere Bohrung angebracht.

Danke Fendant für die Antwort.
Und es gibt keine Chance den alten Sensor zu entfernen und und die vorhandene Bohrung zu nutzen?

Hi Rolf,
the flange for the Philippi sensor did not fit into the recess with the thread for the crappy Hanse sensor. As it was watertight I did just leave it in.
For me it was easier to make a new hole for the flange. Installation was completed within 30 minutes. Not that I reused two wires of the old cable for the connection to the Würth panel. You can make a new stainless flange for the sensor, but you have only a very small surface to get the flange watertight.
I also installed a Philippi tank monitor for fuel ( also replaced the cheapo unreliable Hanse tank sensor), freshwater, greywater and an ultrasonic sensor for the blackwater.

Thank you very much Frank.
As soon as I know the exact tank depth for our 385, I will do the installation as you did.

Hi all, 
Upon our return from a regular Saturday sail there was a flashing red light on the main panel and a message fresh water 25% which was a reasonable reflection of the water volume in the tank.  I have added fresh water to the tank and now the readout indicates 0% and the red light still flashes. 
What could be the cause and what advice/ help can anyone give.
Our boat FULL TILT   is a  385  built  2016   
regards Martin & Rena
