General Info: Potable water gauge reads full until almost empty

[Dragon Lady]

Hi Guys,

My Lavezzi 40 potable water gauge reads full until the tank is almost empty then drops to the actual level which is a bit of a pain.
I suspect it is a sender problem and yesterday I found the sender but before I go ripping it all apart I would like to know if anyone else has had a similar problem particularly on a FP cat and what the did to fix it?

Mine is a capacitive sender, easy to replace. Be sure to match the depth of the tank and the gauge (mine is 12v - 4/20ma).

~$66 US

It could have US senders and a Euro gauge or vice versa. That would cause the meter to reverse.

Thanks guys, the gauge works the correct way, there must be a short or some other defect.
Looks like a new sender is the go.

Marine Gauge Systems offers a solid state replacement for US type senders (30-270ohms). The easiest way to verify a US type gauge is to short (connect), the sender leads on the back of the gauge. If it goes to full scale, it is US. If it indicates empty, it is a Eurpoean model.

We went with a water meter... Fill the tank and count down the actual water used or filled from the water maker. Less than 250 with remote digital display

I have been considering a water flow meter. What brand/model did you use?
