Emerson Process Management has added the Micro Motion ELITE CMFS sensor platform to its line of Coriolis flowmeters to deliver precise measurement to smaller pipeline sizes of less than 2 inches or DN50.
When flowmeters are used to measure flow, they measure one of a number of fluid types. One common way to divide up fluid types is between liquid, gas and steam. These types can be further subdivided. Types of liquid include oil, water and industrial liquids.
There are several types of flow meters used to measure the flow profile of a fluid. They are; turbine flow meters, ultrasonic flow meters, magnetic flow meters, Coriolis flow meters and target flow meters.
The flow measurement performance of two commercially available ultrasonic flow meters has been evaluated under conditions in which there were various levels of contaminate-like coating applied to the inside wall of the pipe upstream of the meter.
Ultrasonic flow meters are among the most popular of the flow meter types. They are used for a wide range of applications, including natural gas and petroleum liquids custody transfer, check metering and flare gas measurement.
Custody transfer measurement in the oil and gas business has been described many ways. It has been called an accuracy in measurement that both the buyer and seller can agree upon and it has been called the best that can be achieved to meet the contract conditions.
Well-known throughout the flow measurement industry, Jesse Yoder is founder and CEO of Flow Research, Wakefield, MA. Since 2000, he has focused principally on world markets for flow, pressure and temperature devices as they are employed in the energy business. He excels in his chosen pursuit by the force of his intelligence, his enthusiasm and his research and writing aptitude.

Duke Energy uses a GE Frame 5 gas turbine to drive a compressor used in a natural gas pipeline. The intake system required retrofitting with a silencer to meet current regulations and the need also existed to reduce particle contamination. The pressure drop in the initial design was found to be 8.5 inches of water, much higher than the design specification which was 5.3 inches.
As traditional natural gas reservoirs are depleted, producers are forced to target lower pressure wells that typically produce a “wet gas.”
