ABSTRACT:
A hand-held, remote reading, liquid level measuring device, also suitable for measuring specific gravity or other parameters of the liquid, containing a supply of gauge liquid which is spill-proof in any position of the measuring device and with the measuring device becoming inoperative upon positions which would give excessive error in liquid level measurement readings. A unique combined pump check valve is also disclosed. A method is disclosed for accurately inserting a tube within the liquid to be measured so as to simulate the level measurement on a conventional dipstick.
