OT- Looking for bathroom type scale with low weight alarm
Posted by: azdave ()

Okay experts. Can anyone recommend a bathroom or UPS type floor scale that has the ability to set an alarm sound or indicator light if the object on the scale falls below a preset minimum?

Specifically, I'm trying to monitor when 5-gallon pails of coating material have nearly been emptied so the sprayer pumps don't suck air. I want to measure by weight, not by mechanical means that touch the liquid. Ultrasonic might be another solution but I worry about sensor fouling due to stirring or splashing. Thought I would try by weight first.

High resolution is not critical (+/- 0.5 pound would work) and a 0-100 measuring range would suffice as we are generally measuring in the 80-10 lb range between full to empty.

I'm sure I can build one but figured there has to be a ready-made solution out there to evaluate first. Even a simple teeter-totter could trigger a switch when it moves but I'm looking for something a little more elegant. This will be in a fixed location in a shop so portability and construction site ruggedness is not required.

Some aircraft water ta is have weight sensitive pads that wl trigger a light when tank is low on water. You might want to look into that system.

I have found plenty of pads and mats that trigger an alarm when someone gets out of a chair or rolls out of a hospital bed. Not quite what I'm looking for but I'll check the water tank application.

That may do the trick. Will have to read up on it. Thanks.

Didn't see anythings about an alarm built into that one and don't want to run a PC to monitor the output. We already use scales like that in our shipping areas.

We've started using a lot of guided wave radar to monitor material levels without actually touching the material, works for most anything.
