Why do I still look at my tankl level gauges?

[opnspaces]

I was just thinking about this. I know we are all familiar with stock tank level gauges not being accurate. On my trailer sometimes I push the button and the level looks right. And sometimes I push the button and know in my head that there is no way it's that full. So it brings up the questions?

Why do I press the button at all?

• If the reading seems high I ignore it because these sensors all stink.
• If the level seems about right I believe it. But then how do I know it's not actually wrong?

I guess my theory is that based on the way the sensors work it is safe to say they may read high, but they will never read low.

What's your theory, Am I on the right track or all full of p@@p?

DSDP Don, I have to think if a 40 or more gallon black tank only lasts 2.5 days, you need to cut down on the beer. ??

You push the button to see if a Miracle has happened and the sensors are working as they should instead of as they do.. Of course they are not. but hey. Faith springs eternal they say.

I press it 'cuz the fresh water sensor works and I judge everything by that. We can fill up the FW tank twice before we need to dump. We do put lots of dishwater down the toilet.

Pure entertainment value.

I know people spend hundreds of dollars on monitoring systems and then pretty much ignore them. When you dump, it's often more determined by where you're at and when you're moving onto the next campsite. I know the black tank in my Dutch Star is good for 2.5 days and is full. So every two days, I just hit the electric drain switch and the black tank dumps. My grey is always empty as I have a bypass on my SaniCon. To be fair, my electric toilets have a ight that goes form yellow to red as the tank nears full.

I think people have a weird addiction to knowing exacty what's in their tanks, when it's not that big a deal. Often installing a SeeLevel or some other brand is a satisfying gadget installation.

The standard sensors detect when something conducts betwen the probes. It's not hard to have stuff clinging to the tank walls and giving too high readings. it's much, much harder for there to be a submerged bubble of nothingness.

My SeeLevel tank level display has always read correctly, so I do use it regularly. You're probably correct for the "nails in the tank" style monitors though, they don't typically read low.
