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.

Although there are many different hydrogen production types including black, pink, turquoise, and yellow, the most common type is from “grey” sources (95%). The steam/methane reforming process is used to convert natural gas or methane into hydrogen. A pollutant by-product of this process is CO2.
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.
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.
Ski resorts in North America depend on snowfall for enthusiasts to enjoy winter sports such as skiing and snowboarding. However, when nature does not cooperate, artificial snow is required to maintain the base level. Artificial snow consists of small particles of ice that are used to increase the snowpack. It is produced by a machine that uses a high-pressure pump to spray a mist of water into the cold air. The water droplets crystallize to form artificial snow.
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:
Common Results of Gas Uses in Industrial Processes
There are three key results of measuring the flow of air or gases with industrial gas flow meters in industrial applications:
- efficiency improvement
- leak reduction
- increased product quality

It is safe to say that everyone’s goal in process control is to increase reliability of their process measurements. Facilities spend endless resources to identify and displace problematic points, also know as “bad actors”. One common problem area in a refinery is reliably measuring the heavy residual hydrocarbons from the “bottoms” of the distillation towers in the crude unit. Typically, these applications are Vaccum Distillation (VDU) Feed & Delayed Coker (DCU) Feed; also known as crude furnace pass flows.
