What is oil gauging tape used for?
Oil gauging tape is a measuring tool that allows you to measure the amount of liquid in a tank. Commonly used in oil refineries, the gauging tape is lowered down into the tank until the bob, or dipstick, touches the bottom. Once lowered, the tape is reeled back up and the line where the tape is wet indicates how much liquid is in the tank. They vary anywhere from 18' to 100' in length and can measure in 1/16", 1/8", 1/4", and 1/2" increments.
