Flowmeters play a critical role in today’s process world. As technology has advanced through the decades, a variety of flowmeter technologies has expanded the ways, customers, control and monitor their utilities, steam, fiscal metering, etc. Today, a few of the top flowmeters on the market are the Coriolis, magnetic, vortex, ultrasonic, differential pressure, and variable area meters. Several other technologies, such as turbine, thermal mass, and positive displacement, are also available. Since each flowmeter has positive and negative attributes, careful consideration is required to avoid purchasing a technology that is inappropriate to the application.

Mass flow controllers offer precision gas flow control to many critical industries including biopharm, semicon, food & beverage, manufacturing, and R&D. As the technology demands increase in these sectors, so does the demand for precision gas flow control systems. The more accurate and repeatable the gas flow control the better the yield, the higher the product quality and the lower the cost in wasted materials.
Flare gas stacks and combustors are used in many industries including oil & gas, industrial, biogas, and wastewater treatment. These systems are important for burning waste gases produced during operations such as drilling, chemical processing, or biogas reclamation.
In some locations, drilling for oil or natural gas releases hydrocarbon gases that can’t be captured and used, so a gas flare or combustor is needed to relieve excess pressure in the system. Flaring is also used during construction, testing, and maintenance of newly drilled wells or fracking sites.
Digesters used in landfills or wastewater facilities break down waste and produce methane and carbon dioxide, two greenhouse gases (GHGs) that are typically flared, collected for use as a fuel gas in equipment used at the facility, or stored for sale. Flares burn the biogas or waste gases to minimize harmful GHG emissions when flaring becomes necessary due to pressure release events.
Portable flowmeter for liquids, gases, thermal energy and steam
With the new FLUXUS G601 ST, FLEXIM presents the world’s only portable flowmeter for steam. The clamp-on ultrasonic system is also suited for non-invasive flow measurement of virtually any liquid and gas and for recording thermal energy flows.
The accuracy of a thermal mass flow meter is dependent upon the technology type and the quality of the materials used for the meter’s sensor design. A well-designed sensor is made to measure flow accurately over a long period of time with minimal drift, independent of recalibration and calibration validation diagnostics. For a thermal mass flow meter, the materials used in the manufacture of the sensor play a vital role in the overall performance of the sensor. The materials must create the best environment for heat transfer - the essential principle of thermal mass flow measurement - or the accuracy and response time suffer.
What is Flow Rate and Why is It Important in Process Applications?
In an industrial setting, controlling processes with accurate data is an essential part of keeping the process running smoothly. Control systems are equipped with instrumentation like thermal flow meters to feed flow data like gas temperature and gas flow rate into the system. So, what is flow rate and why is it important? The flow rate of the gas tells the system how much of a gas is flowing through a cross section of a pipe at a prescribed unit of time. Flow rate data can help with many things, including the following:

Providing exceptional low-flow sensitivity for accurate measurement over a wide range of flaring operations
Flare stacks and combustors are used to burn waste gases from the plant, converting chemical and organic hydrocarbons into primarily water vapor and CO2. Some processes also use relief valves to vent flammable gases to the flare stack during upset conditions.
Applications include oil and gas well drilling operations, oil refineries, chemical process plants, gas distribution infrastructure, and landfills. Flares are subject to stringent regulations, requiring operators to measure, record and report the amount of flared gases.
Due to the potential for large changes in flow rates, density, pressure and gas composition, flare gas measurement is one of the most difficult and demanding flow applications. Fox Thermal flow meters have demonstrated their ability to measure the low-flow rates typical of normal flare conditions, and also the high velocities found in upset conditions.
Fluid composition and installation anomalies can also affect flow meter performance. Fox Thermal's calibration lab employs a wide range of gases, gas mixtures, temperatures, pressures and line sizes to simulate actual fluid and process conditions. This real-world approach improves installed accuracy and minimizes measurement uncertainty.

Custody Transfer (also known as Fiscal Metering) in the oil & gas industry refers to the transactional transfer of a substance, raw or refined, from one party (owner) to another.
Typically when a custody transfer is taking place, the end goal is to determine the value or payment between two parties for the physical substance (gas or liquid) that has exchanged hands via pipeline. For that reason, the flow instrument that measures the total amount of product changing ownership can be viewed as a cash register between the two parties.
