New Developments In Thermal Dispersion Mass Flow Meters
This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature.

DM Petroleum Operations Relies On FPI Mag Flow Meter For Tough U.S. Strategic Petroleum Reserve Application
New tests recently performed by DM Petroleum Operations Company with the FPI Mag® Flow Meter from McCrometer continue to confirm the flow meter’s accurate performance and reliability on two rugged Texas brine disposal lines supporting the U.S. Strategic Petroleum Reserve (SPR).
Two Phase Flow Considerations For Coriolis Meters
Two phase flow is notoriously problematic for most flow technologies. Read how ABB is tackling the 2-phase flow problem through an entire meter-design approach, which entails a state of the art electronics platform and innovative sensor technology. By Ron DiGiacomo
Advanced Diagnostics of Thermal Mass Flow Meters
Many thermal mass flow meters are of the insertion type. As a starting point, proper insertion depth and straight run per the manufacturer’s recommendations should be adhered to.
Electromagnetic Flowmeter Survives Floods
When the Village of Windsor, New York replaced its mechanical flowmeter with an electromagnetic flowmeter in 2003, it was with high hopes that the newer technology would be less prone to failure and require less maintenance.
Advantages Of Thermal Dispersion Switches For Pump Protection
Thermal dispersion switches use similar principles as thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD.
Versatility Of Thermal Mass Flow Meters
There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.
How To Select A Flowmeter Technology To Minimize Annual Energy Costs
Selecting the right technology for a flow measurement application can be a daunting task. In the case that several technologies will work for a particular application, minimizing energy costs can help narrow the selection. This article discusses ways to assess the energy costs associated with a particular flowmeter technology to inform your decision.
Flow measurement & control
The oil and gas industry is one of those areas that rely on flow measurement and control products to ensure efficiency, safety and accuracy in production. Some of the flow measurement instruments and products that are used in the petrochemical industry include multiphase meters and water-cut meters. These instruments offer solution to all topside and downhole installation needs. Flow measurement and control instruments need to be accurate to ensure that production percentages are not exaggerated or understated.
The flow meters used in the oil and gas industries can either be portable or fixed installation types. The portable flow meters are normally used in areas that range from troubleshooting to testing and servicing. The fixed installation flow meters are mainly used in functions that are permanent or less frequent to changes. There are certain attributes that ought to be considered in a flow meter before it is purchased. Ease of use and accuracy is a trait that all measurement instruments need to possess. All portable flow meters need to be flexible while the fixed installation meters need to durable and versatile.
Most manufacturers have metering specialists who will help with all the stages from need evaluation to design and installation. This helps since the final product will be that which is specific to the needs of an individual oil or gas site. There are software designed to help with optimization and facilitate instantaneous monitoring. All the installations will be integrated to ensure a fit-for-function solution.
Other than the flow instrumentation, control instruments are the other fundamental component of oil and gas exploration. Control valves are one important part of the control system that ensures that production is maximized with efficiency and the process is seamless. These valves are useful in pressure relief and reduction as well as back pressure regulation. Control systems are installed in compressors and pumps to regulate pressure and flow rates respectively.
