Retrofit clean water tank level guage

[scruff]

I've got a moody 34 with GRP under berth water tanks. These frustratingly do not have level sensors which contributed to running out of drinking water in West loch Tarbert on west coast of Jura - just a little inconvienient.

Is it a simple enough job to retrofit a sensor & guage? By preference it'd be a readout on the switch board by the navy station.

Thanks.

There have been a few threads on this. How easy it is depends on the tanks. If they are stainless you may have difficulty cutting the 32mm hole needed for the Kus type sensor https://www.ebay.co.uk/itm/350mm-KU...vel+sensor&_from=R40&rt=nc&_trksid=m570.l1313
I made simple systems for my under bunk tanks using the type of gauge that has LED lights to indicate level http://cpc.farnell.com/kemo-electro...l7hITfx45PLUY7fRoMYTnAMLKjozk4CRoC5VYQAvD_BwE.

I fitted a gauge to my M33 a few years ago. No idea of the make but battery operated(2 x AA from memory?) - you just have to have a length of 9(or 10?) core lightweight cable which you cut each wire to a required depth. Not a good description I'm afraid. This cable is wired to a display which shows the depth in a series of led's but a push button. Only a few pounds from memory. I'm going to the boat on Thursday so will get the name, it was from Germany from memory.
Update - this appears to be an update from the one I fitted:- https://www.ebay.co.uk/itm/Kemo-m16...628701&hash=item1ed228da3b:g:h7YAAOSwiylXB1af

The make is Kemo, its the same type of installation I wrote up in PBO August 2016, using a small buck converter to provide the 3 volt supply.

+1 for Kemo.

Search for that here and quite a lot will turn up - I posted in 2015 about using a Kemo system with a sender made from ribbon cable here http://www.ybw.com/forums/showthread.php?436953-Fresh-Water-Tank-Full-Alarm&highlight=kemo and there have been further posts since on various water gauge threads.

You can install this in the tank
https://wema.co.uk/products/hfl-flange-1
then you can chose a level sensor with 1 1/4 BSP treads.
I installed this one, NMEA 2000 calibrated to give correct values
