Gauges for Fat Sacs

Has anyone on here tried or thought about a way to make a gauge for fat sacs to so you could see how full they were without looking? I realize it's not that big of a deal to just open the hatches and look, but it would be cool to not have to. I have some ideas but I'm not sure if it would actually work or be cost effective.

Timer module with an output to a gauge. Tige does it on their 2010's, but it's not shown on a gauge, but the LCD screen.

I don't know what type of senders they use, but you can buy the nautique gauges

It would seem that you would have to use some sort of flow meter on the input to each bag to gauge how much water is going in.

I was was gonna say some kind of flow meter would be the best. So ^^^^^^^^^^ X2.

Yea using a flow meter was what I was thinking of too. You would have to run the output signal from the flow rate sensor through some circuitry to convert it to a signal that corresponds to a volume that has passed through the flow meter. Then your gauge would also have to be calibrated to match the signal corresponding to the volume.

Just put a vent line on your sac. When you hear water coming out the side of your boat you know its full. Cheap and easy
