I got caught out many years ago with a false gauge glass (Klinger) reading fairly elementary really but what happened was we were traversing a LONG hill in the Cotswolds and not making steam, the glass showed 1" in the bottom this was because the gauge glass was connected to what would have been the "normal" connections, one at the top of boiler and one about 6" lower, the bottom of the G.G was connected to the lower point and as a result of the hill climb the connecting pipe sloped up hill (horizontal when on the level) consequently the pipe filled with condensate and thereby showed 1" of water, but non in the boiler, the bottom of the G.G is now connected to the bottom of the boiler so this can not happen again , no trouble since.
