1. A reference electrode. The basic function of the reference electrode is to maintain a constant potential and use it as a control for measuring various deviation potentials. The silver-silver oxide electrode is a commonly used reference electrode in pH meters. 2. A glass electrode. Its potential depends on the pH of the surrounding solution.

Coriolis mass flow meters usually are calibrated on water because the constants are valid for all other liquids. Calibration for density is usually done by filling tubes with two or more (stagnant) calibration fluids of known densities. Accuracy & Rangeability. Coriolis meters provide 0.1-2% of rate inaccuracy of a mass flow range of up to 100:1.
