Propane Tank level question

[Nevrdun]

My tank level indicator seems to be showing red even though I know both tanks are full or near full. Please see photo. Can anyone tell me what my issue may be? Thank you for any input you may provide.

Unfortunately only one cylinder is shown. I see the cylinder gauge says 1/4 and should be enough to keep the changeover indicator green.

I agree the changeover valve is functioning poorly and should be replaced. I recommend Cavagna brand as a replacement.

The only problem I see with the changeover indicator is the missing black cap. A strip of tape covering the red would fix that.

Thank God Doug is around...

Except Doug's post about the horizontal tanks and gauges referred to the wrong indicator. It's the red/green indicator at the changeover valve with the missing cap that's causing the OP's problem.

Thanks everyone! Much appreciated.

A quick interim fix would be a strip of colored vinyl tape covering the red portion.

Buy 2 new regulators. Buy regulators with easy to read RED/Green window indicators.

Why? He has a dual regulator with two inputs and auto switch over now.

If it was there then you would only see the green at the bottom, then when the tank you are running from goes empty the red would drop down into view.
You are missing a piece, go to your local rv parts store and look at new regulators.

On this point you are correct. This is a Marshall Excelsior MEGR253 regulator and indeed the black cap is missing, which covers all but the bottom 3/8 in of the clear window (I just measured mine).

Which indicator are you talking about?
- The gauge on the tank
- The pop up button on the regulator

I have to assume since he said gauge and noted that the tanks are full but his tank gauge reads something like 1/4, that he is referring to the one on the tank, but yes, he needs to clarify this.

Reference the 2021 Marshall Excelsior RV/Camping catalog (a huge source of information, not just a catalog). See page 6 (8 of 40 in the PDF numbering)

I apologize if I offended anyone, but Doug is correct on this one.

1. Those are HORIZONTAL tanks.

3. Makes NO difference if tank on or off.
4. REGULATOR REPLACEMENT???????????????????????????????? WHY
5. Yes, if OVERFULL the gauge may do that
6. If tank upside down it will do that Rotate 180 degrees and see what happens
7. Sometimes a float can get "stuck" inside the cylinder. Remove the cylinders MAKE SURE they are really full. Then lay down or rotate 360 degrees a few times to free up stuck float.
8. This is the BEST and ONLY type level gauge system that always works, as it uses a inside float to gauge fluid level. It is the same design used on ASME motorhome tanks. Doug

The OP should not pay attention to ANY other post but Doug's. He is absolutely correct. The other posts make no sense. I'm sitting here thinking, "how do I reply to all this gibberish and mis-information" then I saw Doug's post.

Thank you. Can you suggest where I would get the regulators?

You don't buy new regulators. You purchase a Auto switch over valve. Doug

PS I misread your problem

Are tanks turned off?
