Coriolis flow measurement technology is roughly 25 years old. However, until the early 1990s, the technology was generally viewed as “not working” on gas applications.
Micro Motion introduced Coriolis meter designs in the early 1990s that solved the technical hurdles of gas measurement, but there was still a widespread belief that Coriolis meters were unfit for gas applications.To help combat these perceptions about Coriolis meters, Micro Motion conducted a wide range of tests at Southwest Research Institute (SwRI) in Texas, Colorado, Engineering Experimental Station (CEESI) in Colorado, Pigsar/Ruhrgas in Germany, and Gasunie in the Netherlands to prove Coriolis' suitability for gas measurement. The tests demonstrated not only that Coriolis meters perform extremely well in gas applications, but that Coriolis meters can be calibrated on water and that calibration is transferable to gas applications.
