摘要 |
A liquid level indicator comprises a mercury-filled U-tube having a plurality of branches and calibrating rods for insertion into the branches. One arm of the U-tube is subject to the hydrostatic pressure in the receptacle holding the liquid whose level is to be indicated, and the level of mercury in the other arm indicates the liquid level via a colored liquid.
