    We have had a strange time with our Gaslow. Had the system for some years and it has all worked OK.
    Refilled last time and the LPG pump looked brand new, In found it on the internet, a Repsol garage in Chicklana Spain.
    Arrived to fill up and saw a totally different filler than ever before, so off to reception where with hand signs etc the Spanish guy produced some adapters, all brand new in a box. We then compared them to my adapter and found one that did the job.
    So filled up we got on our way.
    Fast forward to when the next tank was empty and switch over to the one filled as above and the gauge shows half!
    Went to fill second tank, no problem, and at the same time got the guy to check the other tank. It's full was his reply, although as I pointed out the gauge showed half. Switch over to the full tank and gauge shows full.
    Now been using the "half full" tank for a month with gauge sloooooowly going down.
    Any ideas why this could happen?

    The gauges are only rudimentary affairs and cannot be relied on to be totally accurate in my experience.

    The Gaslow gauge should show full when full and not start to move until it is down to 50%. That is the nature of it and if not doing that it is not working to design.

    Mine older than that Andy, the gauge is separate with the regulator.
    After having a Galow system for ten years I am used to their inaccuracies but never seen this happen before. The same gauge measures both bottles so why is the first bottle showing different levels to the second at the same time, I cannot understand it. ?

    In that case the only way to prove they are filling fully is to fill them and then take them out and compare weights

    i would think if the gauge monitors both bottles its a pressure gauge more than a true fill level as shown in tecnos drawing and will be very inaccurate as the pressure of the vapourised gas remains fairly constant until very nearly empty

    Yes it is a pressure gauge and I agree with you as experience as shown me.
    I thought at first the gauge was faulty but as it shows full when connected on one but not on the other I cannot see how it can do that.
    I did wonder whether the fact that it was a new installation at the Repsol garage may have had anything to do with it.

    if it's a pressure gauge then it must be very sensitive and have a huge offset to represent the liquid phase of the LPG as a level indication.
    Most likely it's as the drawing and a mechanical float or displacer, hence the short unrepresentative range. I have the alugas type and it can be slightly sticky in it's response when filling and I'd imagine the mechanism could get jammed with contamination over time.

    We have two Gaslow bottles and quite a while back the gauge on the one in use showed empty for weeks before finally running out, they really aren't to be trusted but with two it's not so much of a problem!

    You will get an idea of how much you use.
    I look to fill up after I have used one bottle
