Q: How do I select the right digital gas flow meter for my application?

A: Selecting the right flow meter depends on several factors, including pipe size, flow rate,gas being measured, temperature and pressure of the gas, and whether the flow rate needs to be local or remote. View our Gas Flow Chart for more information on selecting the best MFC for your application.

Q: How do thermal flow meters work?

A: An industrial thermal mass flow meter measures either the mass velocity at a point in aflowinggas, or the total mass flow rate through a channel or pipe. Learn more about thermal mass flow meter technology used to measure gas flow more efficiently. Watch the video to learn more about How Thermal Mass Flow Meter Technology Works.

Q: What is mass flow rate? 

A: Simply put, the mass flow rate is the WEIGHT of the sample, while the volumetric flow rate is the SIZE of the sample. 

Boiler MACT Certified

Flow meters for gas measurement are also ideal for compliance for Boiler MACT regulations for inlet fuel measurement for area source boilers (40 CFR 63, subpart JJJJJJ) and for major source boilers (40 CFR 63, subpart DDDDD). Read the following article to learn more about how our mass flow meters and controllers can help with Tuning Your Boiler for EPA Boiler MACT Compliance.

Gas Flow Measurement

In the world of gas flow measurement, there are multiple technologies available, including:

• Thermal flow meters
• Differential pressure flow meters
• Ultrasonic flow meters
• Coriolis flow meters
• Mechanical flow meters

These technologies cover all ranges of gas flow applications, including:

Research, Product Design, and Development

• Flow analyzers are used during the development of mechanical ventilators, anesthesia workstations, CPAPs and BPAPs, and oxygen concentrators 
• Flow meters are important for the development of pumps, valves, molds, nebulizers, inhalers, gas delivery systems, and more
• EOM flow sensors are embedded in medical devices that function using gas flows

Medical Device and Light Industrial Manufacturing

• Flow analyzers are used in testing and quality assurance of flow, pressures, volume, and mechanical breathing parameters 
• Flow meters are used for testing and quality assurance of a wide variety of pneumatic flows

Field Service

• Manufacturers, biomedical technicians, field service engineers, and clinical technicians use flow analyzers to test whether medical equipment is functioning properly and perform service when needed

Calibration and Metrology

• Flow meters and primary calibrators are used by air sampling device manufacturers and industrial hygienists to calibrate inlet flows of particle counters and pumps

Top Choice&#;Thermal flow meters for gas flow measurement

Thermal gas flow measurement is one of the most common technologies available today. It consists of two primary methods for measuring gas flow, including.

• Capillary Laminar By-Pass
• Constant Temperature Loss/Constant Temperature Anemometery

Thermal gas flow measurement is popular as it provides large flow ranges with one instrument, has an extremely fast signal response, can be used in a wide range of applications, and is relatively inexpensive. It also provides high speed signal response and wide dynamic flow ranges. TSI Flow Meters take it further by providing a industry-unique flow body design that allows for minimal back pressure that helps ensure that true flow readings are provided.
