Oil Guage (petrometer) - Is it accurate before or after you push the 'button' on top

When I check the oil I get a lower value when I first inspect the gauge, there is a 'pump' type valve at top. When I give that a few pumps the value jumps up. Is the original resting value or the post pump value the correct reading?

    When you finish pumping the value shown is the oil level in gallons in the tank.

    After you make that expensive repair and you still have the same problem, What will you check next?

    The old one this place came with had a square dial and a plunger located on the bottom.

    Could be a stupid question and I think I've asked before but I can't remember.

    Is there any reason no one ever uses a gauge glass like on a steam boiler on an oil tank? Wouldn't that be much simpler and always dead accurate vs all of the convoluted contraptions they sell?

    The level gauge mentioned in this post is for buried tanks . Glass on above ground tank ? I would be afraid , pressure alone from a oil delivery , 42' gauge glass and glass . I recommend the Rocket type gauge for COD home owners .

    Gauge glasses are used on industrial boilers and steam engines and even standard ones are rated several hundred psi at high temperature, but sure..... Pressure from an oil delivery is scary.......

    I don't believe that the high pressure steam boiler glass tubes at lengths over 36" with the associated fittings and tank tappings are practical when the Scully econo-gauge is so inexpensive.
