better ballast tank level sender

Would anyone who has removed their hard tanks be willing to donate their tank level senders to me? I will pay shipping. I want 2 or 3 units to experiment on. I would like to try to see if there is any way to make these things more reliable. I would like some that are compatible with 2006 boats.

As most people know, you can set them and they will work for about 1 day and then they are out of whack again. I'm an engineer and I work with a lot of other engineers, so I wanted to take a run at trying to improve these things. I'll definitely pass on any findings to the community.

Good luck with this project! And put me first in line for 3 when you ultimately come up with a great solution.

No one has any old senders they want to donate to the cause?

Let me see if I can find the three I pulled out of my boat. PM me a shipping address.

Did you ever find a solution? My resistor / read switch pcb is ok but looks like there is a break in the small pcb located in the hexagon nut.

No way to get at that pcb

No, never found anything to work. These sensors work off reluctance. The problem with that is the reluctance changes all the time with water. You can dial in the sensors to work perfectly one day. Then the next time that you go out, they are off again. They would work if the lake water stayed the same for day to day. It's too much trouble to dial them in every time you go out on the water.

I am looking for a replacement sensor for my starboard tank - the top part of the sensor is broken off - I 'might' be able to rewire the thing - but it might not be so easy to make work.

Anyone know what the replacement part is? Or if there's a suitable alternative?

thanks

Cletus

@blackhawk

I've had the some frustration and been thinking of different ways to tinker with this. I'm also an engineer My best idea so far (but haven't tried) is to get these:
https://www.amazon.com/DAE-MJ-75-Pot.../dp/B01IZ522M0
https://www.amazon.com/DAE-Electroni.../dp/B071XDGWF9

About $110 per tank but you could stick the flow sensor in line and the gauge at the dash. It would count exactly how many gallons you have pumped in and out and you wouldn't always know exactly how full or empty they are. This is likely overkill but I think would solve the problem in a far more reliable and accurate to measure way.

As a side note, I did this with my fuel line so I know to the 1/10 of a gallon exactly my remaining gas - been using it for years and far more reliable than then fuel gauge. The parts are a bit more complex since that's a high pressure line.

But anyway, I'm half tempted to order these and try it it but not exactly sure yet. I hate the idea of dropping $300 just to know what's in the tanks but I also find the gauges close to useless and always have to ask people to move or fear I'm overfilling the piggy-back ballast which for me end up crushing some of my rear panels and other stuff. Just to know how close to done as we are filling would be nice.

Curious your thoughts.

I replaced all mine with WEMA sendors a while back and have had no issues since. There's a thread on here somewhere about it, which is where I found out about them.

There was a guy on here that did a similar thing on the fuel tank. Put a sensor in that measure the weight of the fuel used. Pretty cool.
