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:

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

Excessive gas consumption wastes money - and of greater importance - can affect product quality and safety. The pharmaceutical industry uses large quantities of nitrogen, oxygen, carbon dioxide gas, and air. Without good air and gas flow measurement, cost, quality, and consumer safety will suffer.

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.
