Ullage bar

An essential tool for obtaining highly accurate ullage measurements (with the measuring tape).  

The bar is attached to the measuring tape (without damaging it) at the desired height. The tape and its weight are lowered into the tank to be measured and the bar is placed over the ullage opening. The ullage corresponds to the length of tape between the plate and the point where the product wets the tape.  

Liquid-finder pastes are used to determine the exact point where the product touches the tape.
