Steam measurement is always a challenge. Traditionally, Pitot Tubes and Orifices Plates are used for this application but are of low accuracy and low
range-ability. Typically the ID of the process tube is unknown and the straight pipe requirements are difficult to meet. Steam is almost always a non-homogenous fluid, with cavitation, shocks and other irregularities.
Steam being used in breweries had always been overlooked as a source of “reusable” or “capturable” energy. Typically used for steam flow measurement (usage), orifice plates and averaging Pitot tubes proved to be inaccurate, required costly, extended pipe runs and regular maintenance and replacement. In generating steam, thermal mass meters had been used but presented some of the same problems. Brewers looking to improve their efficiency needed a new method to obtain and measure a thermal mass balance around the plant for steam generation and usage.
