Gas measurment by insertion turbine meter
- GH Flow Automation, Houston, TX (United States)
The gas industry has had a requirement for many years for a simple and reliable cost effective meter to measure gas flow in large diameter pipes, or even in smaller diameter pipes in which the flow cannot be interrupted or the passage obscured. The insertion turbine meter is well suited for this type of flow measurement in a variety of non-custody transfer applications. It is presently used in many applications such as compressor efficiency and surge control, pipeline catastrophic leak detection, pacing odorizers, pacing samplers and checking throughput. There are several commonly desired features associated with the use of an insertion turbine meter. Linearity and repeatability are usually the most important features. Rangeability can be just as important in most applications. Fast response time, negligible pressure drop across the sensing device and easy removability under pressure are usually given requirements for any application considering the use of an insertion turbine meter. Of course in today`s business environment, reliability, simplicity of use and economical justification are absolute given requirements for any product or service being supplied. Peripheral electronic products are used with the insertion turbine meter to provide total flow measurement. These electronic products vary greatly, from basic flow rate and totalizers, to more sophisticated flow computers using pressure and temperature data to perform the flow calculation. Because a variety of peripheral electronic products are available, and because the purpose of this paper is to focus on the insertion turbine meter, the aspects of the electronics will not be covered in detail. This paper describes how the insertion turbine meter can be applied to today`s gas flow measurement requirements. It specifically addresses a description of the physical characteristics of each component, operating principle, application, installation and performance of the insertion turbine meter.
