Abstract: Traditionally orifice meters have been used in wet gas applications rather than gas ultrasonic meters (USM). There are many reasons for this, but certainly one has been the question regarding reliability of a gas ultrasonic meter when subjected to liquid loading. The question is this: How does the accuracy of the orifice compare to the gas USM when liquids exist? Another question might be asked is: Can the USM clearly identify when liquids are present, and give the operator an idea of what gas volume has passed through the meter during this time? To investigate these questions, two different meters were tested at the CEESI Nunn Wet Gas loop in Nunn, Colorado. The first test involved a 4-inch orifice and 4-inch USM in series (the USM was a 4 and 2-path meter all in one body). For the second test a 3-inch orifice and 3- inch, 2-path USM was tested. Both tests involved several flow rates, 2-3 different pressures, and up to 8 different levels of liquid loading. The fluid used in most of the tests was Exxsol, a kind of kerosene that is popular for this type of testing. For the 3-inch tests, a limited number of data sets were also taken using water
