Zanshin Good research job there! If I can't get my digital output working I might opt for one of those as well. Thanks for posting your findings.

gilsurf Success! Daniel L. Jerman Co... They actually have a model that is a totalizer (no reset) with a digital LCD resettable display for batch info away from the unit. And, it is 1/2" female threads, nickel plated bronze.

Zanshin Not quite, it doesn't have an metal fittings, just plastic and has a digital lead glued to the front panel to drive the digital display on the breaker panel. But display panel looks the same. If you PM me your e-mail address I can send you the picture of the valve as it is in-situ.

gilsurf Thanks Zanshin!
Does it look like this?

Zanshin I just checked my boat pictures and found the standard Jeanneau meter; managed to zoom in on the picture and find that it is manufactured by GWF.

gilsurf Thanks for the ideas. As the tanks are integral fiberglass with lids that are not very thick, any form of a float or pressure type gauge may be difficult. Though, the lids will be coming off for a re-seal, so it is a good time to look closely at this.

OW, it seems a simple clicker flow meter would be fine. The Grainger option states: Not for Use with Water Applications. It seems there must be a simple (and cheap?) water flow meter with a total amount passed out there.

On to the search.

Thanks!
Gil

jones2r Giu,

"I know I have 3, all different size. The gages only say full, half etc."

As I understand you, you have three floats installed in a single tank, all sending to one gauge. So, the height of each float is coordinated with the shape of the tank, and the gauge face is marked to indicate the tank proportion for each sender. Innovative.

They make floaters that have different height shafts because of that.

If he knows the quantity of water it takes, then its easy to calculate the quantity indicated.

Also most of them, can be calibrated for float travel, ie what is marked with float all down and all up.

camaraderie You might want to consider this as well...minimally invasive and works pretty well for both fuel and water.
