Gas Measurement

Measurement and regulation are an integral part of the production of gas. As the value of gas has increased, the need for more accurate measurement has become apparent. Technical Data used in the field explained in diploma in petroleum technology.

Proper regulation is necessary to prevent unnecessary flaring or production curtailment. Today the engineer has a choice from among many instruments and controls, some of which are rather sophisticated. The advent of electronic and digital equipment offers many alternatives. Remote metering and control now are more commonly employed to minimize personnel overhead. The net result is a more complex production system than the traditional one.

Many seemingly superior instruments and controls are not suitable for some production systems. They may not be packaged to withstand exposure to the weather and elements in the environment-rain, salt spray, sand. Some more details of diploma in petroleum technology are as under.

wind, lightning, etc. Some devices are so sensitive that  mere vibration may be a problem. Calibration and other like necessities may be inconvenient (or maybe impractical) in remote locations. Also, properly trained personnel may not be available for maintenance.

If transfer of custody is involved, contractural obligation may limit the choice of system. Other factors like spare parts availability and vendor service all influence the proper selection of equipment and vendor.

The choice of meter depends on the absolute volume involved and the rangeability-the ratio of maximum to minimum flow rate that a given size meter can accommodate. Reliability also is a factor. Both accuracy and precision must be cdnsidered. Accuracy is the difference between true and measured rate. Precision is the repeatability of a measurement, however wrong it  may be. There are a series of volumetric meters that measure volume directly by use of bellows, reciprocating pistons, rotating vanes and cams, etc. ’ These are used primarily for measuring small volumes of low-pressure gas and have little application in production operations. A velocity meter is any device that measures flow by impact kinetic energy or by using the change in pressure that accompanies a controlled change in velocity. However this change is induced, meter performance is governed by an energy balance.
