Since the early 1980s, Coriolis meters have gained worldwide acceptance in gas, liquid, and slurry applications with an installed base of more than one million units. Through significant design enhancements in the early 1990s Coriolis meters have rapidly gained worldwide acceptance in gas phase applications with over 100,000 meters installed worldwide and most notably the …

The scientific community has known about fluidic oscillation as a measurement technology for many years. Continuing advances in technology make this type of metering a compelling alternative to mechanical gas meters. This paper will discuss fundamentals of operation, as well as features and benefits of this technology for the user. Based on Bernoullis Theory – …

Fundamentals of Fluidic Oscillation Measurement Alternative to rotary meter measurement Read More »

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 …

Much effort is spent to achieve accurate measurement. Up to date measurement standards, modern meter station design, high quality equipment, and proper measurement operations are all necessary for measurement accuracy. Unfortunately these processes do not assure measurement accuracy if the contract does not also support accurate measurement. The contract impacts measurement accuracy by what it …

Desiccants, Moisture and Corrosion Control, VCI ABSTRACT This presentation addresses problems associated with moisture and corrosion caused by high relative humidity and airborne contaminants. By controlling moisture and corrosion long-term, many problems associated with sensitive field electronics can be avoided

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 …

Definition Supervisory Control and Data Acquisition SCADA information in the energy sector is typically used for near real time decision making for well, pipeline or compressor station operation. It is also key information for displaying to SCADA screens for providing visual acuity in a concentrated view of the operation, such as a tank levels for …

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 …
