Re: Water Flow Meter
There are quite a few water meters available on the market designed for garden hose applications, which are a little fragile for a water system you would rely on for passage making.
Higher quality units are available on Amazon and the like, but the problem I've found is that they are designed for a specific minimum straight run of a larger diameter pipe than we generally use on a boat. Therefore, the would not be very accurate if MacGyvered into a boat system. I suppose in time you could interpolate the readings, though.
Something like this is an easy install and reasonably accurate as to quantity F-3/4-1/2-1/4 E, but not in specific gallons.

Re: Water Flow Meter
This may be a good unit:
Neptune Water Monitor for your boat's freshwater tank: The first accurate and resettable water usage monitoring system for boat's and motoryacht's freshwater systems. Available in both US Gallons and Cubic Meters (accurate down to 1/20 litre)
This epoxy coated bronze meter is installed on the discharge or pressure side of your boat's freshwater pump complete with swivel couplings with 3/4" NPT ends. Accurate to within 1-1/2%. This meter was tested and approved by the California Dept. of Weights and Measures so you know it is accurate. The contact head register on the meter closes a microswitch every time 1 gallon passes through the meter. The remote resettable LCD register then advances by 1 gallon to indicate the amount of water consumed. Deduct this from your water tank capacity and you will know within 1-1/2% how much water is left, eliminating unnecessary fillups and delays.
This self powered remote register with a 10 year lithium battery is installed in any convenient and easily visible location you chose and connected to the meter with the included low voltage wire. You can put it in the galley, the head, the helm or by your engine access hatch. When you fill up just push the button on the remote and it resets to zero, ready to monitor again. As we know most water hoses run about 3 gallons per minute and much less if the marina is busy.
Filling that water tank can take more than 60 minutes so why do it if you don't have to just to be sure you won't run out. This water meter is accurate within 1-1/2% and is far superior to the various tank level monitors that can be off by 25% or more. Commercial vessels and vessels for hire must be certain they don't run out of freshwater and should have this system.
This accurate, durable and reliable system is priced at $199.95 including UPS shipping to anywhere in the Continental USA, a small price to be certain you won't run out of water on your next cruise or on the hook in your favorite spot.
We can ship your order the same day we receive it via UPS. We accept visa/mastercard/discover and PAYPAL to email@example.com. You can fax, e-mail or phone in your order. Feel free to call us toll free 800-654-3733 if you have a question on this or any one of our many water and oil metering products.

|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.|

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.|

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.|

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.

"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.

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.
