Tank monitors/gauges

[Just us]

Hoping to find 1 device that can monitor my fiberglass waste holding tank and 2 Steel water tanks using external sensors. Any recommendations? Thanks!

Hart Tank Tender. Low tech, super easy to install, non-integrated, and no electrical issues.

I have looked at the hart tank tender, but from what I have read I don't think it will work with my water tanks which come right up to the floor and not enough room between the access panel and where the mounting unit fits on top of the tank. I have been looking at the sensors that mount on the outside walls of the tank and trying to find one for both fiberglass and steel tanks

I purchased a water tank sensor that attaches to the outside of a plastic tank for around $100us I think. I have not been successful in getting it to work. Hope you have better luck.

+1. I've owned one for about twenty years now across two boats. Pump is just now needing some maintenance. Cleaned and lubed it this season and its working fine.

You need less than 1" of vertical clearance to mount a tank tender fitting on top of a tank.

The only non-invasive metal tank senders I know of are expensive ultrasonic ones. We have Scad sensors on our plastic holding tanks and they work well. They have a foil strip that stick on the outside.

The hart tank tender looks very good, but it's pricey. What about just using a sight gauge? You'd need adequate space and access but it would be very simple.

Has anyone done this?

Have never seen sight gauges on waste holding tanks (water and fuel only). I expect that sight gauge would get nasty and clogged quickly!

I did used to have rotomolded plastic holding tanks that were translucent...a strong flash light made liquid level in the tank really obvious.

Tank Tenders are a bit pricey, but excellent quality gear. Cost looks a lot better amortized over their long life span.

Right ... missed that part in the OP's question about this being for a holding tank. No -- I would not want a sight gauge there. I guess I'm thinking about my water tank, which is 200 gallons stainless. I may give it a try.
