Over the last several years research has shown that by improving on the flow conditioners used in natural gas metering applications, measurement is improved and installation cost can be reduced. The standards developed for orifice meters (AGA 3/API 14.3 and ISO 5167) addresses the question of flow conditioner design and testing to ensure the meter …

Some major problems and unique solutions will be addressed with gas measurement on offshore platforms in the Gulf of Mexico. This presentation will show the major roll safety, transportation, and weather play in the measurement facility. Proper operation, design, and installation will ensure accurate measurement

The three basic laws we will discuss are Ohm’s law, Kirchhoff’s voltage law, and Kirchhoff’s current law. The main terms used are voltage (units are Volts), current (units are Amps or milliamps), and resistance (units are ohms). These terms by themselves are meaningless unless a relationship can be established. An analogy that we can use …

The United States Department of Transportation (D.O.T.) is a department of the U.S. Federal Government which oversees all issues regarding transportation within the United States of America and U.S. Territories. Its influence around the world is great and widely respected, but its jurisdiction and power of enforcement is limited to the USA and its territories. …

Orifice plate meters are popular for being relatively simple, reliable and inexpensive. Their principles of operation are relatively easily understood. However, traditionally there has been no orifice meter self diagnostic capabilities. In 2008 & 2009 a generic Differential Pressure (DP) meter self diagnostic methodology 1,2 was proposed. In this paper these diagnostic principles are applied …

There are many in our industry who would consider the advancement of the ultrasonic meter to be the greatest improvement in gas measurement in the past twenty years. Its my opinion that the immense improvement in gas measurement is not so much the ultrasonic meter itself. Instead, I believe it is the meters ability to …

Custody transfer ultrasonic gas flow meters are the cash registers of the companies. These cash registers should measure fair and accurately. To determine the accuracy in most of the times only one aspect is taken into account: The calibration: The deviation of an ultrasonic flow meter to the national standards under ideal flowing conditions. Viewing …

We say Advanced Wireless Data Radio Communication Systems Design Process not because this is a more indepth and more technical process, but because the systems involved are complex in nature and must be carefully designed and programmed. If anything, what I want to do is teach you a more simplified approach and technique to design …
