Proper design, maintenance keys to turbine-meter dependability
Northern Natural Gas Co.'s (NNG) 12 years' field experience with turbine-meter measurement has shown turbine meters to provide accurate and dependable measurement. Such accuracy and dependability, however, result from proper design, installation, and maintenance. NNG's experience has been primarily with American and Rockwell turbine meters in town-border sales station settings and especially with Rockwell Auto-Adjust Turbo-Meters since 1982. The most important item in design of the turbine-meter installation is the required length of pipe upstream and down-stream of the turbine meter. The turbine meter is a velocity-measuring device which relies on a uniform flow pattern without jetting or swirl. Minor flow distortions tend to be part of the normal average flow velocity which is directed through the annular passage preceding the rotor, thus minimizing the effect on meter performance.
