Have a customer who lost an oil-bath bearing on a floating barge pump (dewaters the bottom of a guarry) due to a loss of oil. I suggested they at least put a sightglass on it, but that's not going to help much since they are likely too lazy to get out of the truck and walk down to check it.

So I was thinking there has to be a high visibility sightglass available that uses available technology. Is there?

I'd want it to use LEDs, and be solar powered, with a high visibility adjustable level "line" (I'm thinking a translucent day-glo slider). The idea being you could see it clearly from 20-30 feet away. Something simple and self-contained. Have you seen anything similar out in the wild?

Hi Rusty, Maybe slight overkill, but could something like this be possibly hacked to do the job? I have one for my home heating oil tank. Transmits over 150ft.

Des-Case has some nice site glasses, but I don't think they will be visible from a distance.

How big is the reservoir?  There are a lot of cool remote level measuring systems, but I'm thinking they may be overkill on this application.

There's really no reservoir. Just your standard bearing housing. I just have it in my head that a simple, self-contained, self-powered, visual sight glass would have wide application. The problem with all the sightglasses I see is that once the oil darkens a little, it's really hard to see the level, even up close. LED backlighting should solve that. Or even just a bright background in the tube, and a single tiny LED at the top shining down.

I mean, I bought a 6-pack of solar LED walkway lights for less than $20, and they work great. The light/power needed for a sight glass would be tiny by comparison.

Guess I'll just have to build my own.

Rusty,

Can you combine your LED idea with sight glass/leveler from Esco?

https://www.escopro.com/oil-sight-glass.html

Just another product out there

Oh I like the looks of that Esco unit. A replacement 'cap' that contains an LED, battery, and solar cell should be doable.

Rusty,

Search: solar powered walkway lighting

You might be able Hack a low cost solar-light rather than building from scratch.

You might also find kid's glow-in-dark pony-tail rings for putting on oil column.
Ask your Grand Kids or look here:

Walt, yes a low cost solar light for a prototype.  I would want the final product to have a round solar cell just slightly larger than the sight glass cap.  I believe this would have commercial application.

Rusty,

Area = power

Try this little one:

Walt, that one's over 3" diameter.  I'll want one about the size of a quarter.  Will just power a single LED so shouldn't need a lot of power.  I'm convinced there would be a huge market for the right product, especially if it can be sold as a simple replacement for an existing cap.

Rusty,

Well here is a real tiny solar cell with a price you can appreciate:

You will have to see if there is enough power output.
