    Default A different "What is it?"

    Something I started as a weekend project. About half way through, but all the main bits are here:

    Default The Item.

    Hi swk,
    Yes I agree with 1 other, as it is upside down & is a level, & you use water in it, as water finds it's own level.
    I think I'm right ???.

    Suckers , no suction or vacuum, can also be used for slight pressure.

    I remember them for differential air pressure on boiler flues.

    Hope I am on the right tram.

    Given your hobbies I can see this being used in either a pitot-static system or testing aerofoils.

    Maybe.

    Issatree, aint a level as such, but it is upside down (just to make it a little trickier) and does use water.
    Handyjack, on the right tram indeed. To measure slight positive pressure. I also have used them in exactly the same way as you have (in a past life).
    But Durdge39 is closest by far. Chiefly for testing accuracy of pitot systems but can also be used for testing leaks in both the static and pitot plumbing or even sealed spaces (eg fuel tanks).

    Given the amount of fuel tank leaks we deal with each year (read: Piper Cherokee), I might just use the manometer idea for testing them (our low pressure gauge is a PITA to jig up to irregular tanks, and is rather expensive to drop on concrete).
