Freshwater tank sender keeps sticking

[Chris Kraft]

1987 54ft MY replaced sticking freshwater tank sender two years ago. New one still sticks. Tired of tapping top of water tank to get a correct reading. Any ideas what to do about this situation? Are there other senders to consider?

Thanks

Remove and clean them once a year. Clean with sandpaper or scouring pad.

I replaced both of my freshwater tank senders with electric liquid sending units. SSS/SSL Senders with a water level gauge (CPWR) located at my control station with a 3 position toggle switch.
Tank 1 / OFF / Tank 2. I have not had any issues in the past 5 years.

What gauge and sender setup did you use? What manufacturer? Was the install reasonably doable?

 

[SKYCHENEY]

Hart Tank Tender. No moving parts. Nothing that can corrode.

I used "KUS USA GAUGE INSTRUMENTATION" located in Davie Florida. They make a unit that screws directly into the top of the tank, just like the old mechanical units.

So is it just a stainless steel rod with a black float and 2 sending wires? If not, do you have a link to what you installed?

 

[CGHOST4]

Yes it is a Stainless rod with a float that slides up and down, with 2 wires out of the top sending unit.

Would that work with 32V? I have that nearby for the shower sump and bilge pump.... Or I can do a 32V to 12V step down. I have no problem putting the gauge in the side of the bed...... No need to run that all the way to the helm.....

They were formerly known as WEMA.

Be sure and check eBay since there is a guy with lots of new stock at a considerable discount.

It'll be hit or miss on the length but definitely some savings there.

Slightly embarrassing, but I bought two from WEMA five years ago and only installed the one for immediate use.

Last fall I turned the boat upside down to find the other new one, but the eBay price was so cheap (compared with the factory) that I just bought a third one.

This guy I can vouch for:

He made a goof on my order, but replaced it no questions asked and paid shipping both ways--great seller.

The sender just measures resistance, the gauge is what requires power.

Following up, I have the TankEdge (formerly Snake River) Ultra 8, and these standard KUS sensors work fine.

I do run them from my 12V system, and they are capable of the contactless capacitive system mentioned earlier as well.

My boat has a hatch over water tank when i was replacing the pick up tubes I cut a 4 inch O ringed plate in top of tank now I just look in it to see how much water is in tank never fails.
