Tank Monitors

Hi all. Thinking of adding monitors for 2 water, 1 holding and 1 fuel tank. I'd appreciate any suggestions or recommendations based on what you might have tried and had good luck with. It doesn't have to be an integrated system for all tanks, but that would be nice. I'm leaning toward the Tank Tender, but I know there are newer systems out there. Any thoughts?

Thanks, Mike

Tank tender is good as it is ver low maintenance and does not require any electricity. Installation is from above.

The Scad Profile is the best electric monitor by far and fairly easy to install.

I have used both on different boats.

I'm very fond of my SCAD "SOLO" holding tank monitor because there is not intrusion of probes or any openings into the tank.

I am able to view intervals of fill levels easily and accurately.

Take care and joy, Aythya crew

I am looking for a replacement of the basic dial and float that mounts in the top of the water tank. Have not been able to find one online, any suggestions?

I have an Electrosense monitor on my boat. It works great.

I also have the SCAD monitor for thee holding tank. It works well and does not need an internal float. The make 3 tank monitors also. Easy to install as well.

I've often thought of building a multiple tank monitor using a principal I worked on thirty years ago to monitor the level in underground tanks. You build a cheap little manifold from plastic pipe fittings. A flexible PVC hose goes into each tank with weight on the end to hold it on the bottom. Each tank hose connects to the manifold by 1/4 turn valve. An outboard fuel bulb is connected to the manifold. Then you have a vertical clear U-tube on a bulkhead with colored water in it. One end connects to the manifold, the other is open to atmosphere near the ceiling. To check a tank you open the valve for the tank and start squeezing the bulb. The water in the U-tube is displaced from one side to the other until the air starts bubbling out at the bottom of the tank tube. The water level change indicates the inches of level in the tank. Since fuel is lower in specific gravity than water the level rise will be scaled slightly less than actual inches. Close the valve after checking.
