Applications
Thermal mass flow meters are perfectly suited for measuring clean, dry compressed air and inert gases, where accuracy on smaller pipe sizing is important.
Typical applications include:
- Clean, dry compressed air and inert gases
- Process gases
- Clean rooms
- Manufacturing, industrial and pharmaceutical industries
- Vacuums
- Small pipes < DN80
- Low to high flows
- Permanent installation
Important
The sensor must be installed (i) in dry gas, (ii) at 90° to the pipe and (iii) away from bends, edges, seams, changes in pipe size and other obstructions,
Incorrect wiring or installation can give false readings, damage the sensor and void the warranty. If you aren’t sure how to install or wire the sensor, please contact us. Full installation and wiring instructions are available in the User Manual.

Warranty & Calibration
12 month warranty
Calibration is recommended every 2 years (provided the sensor is not exposed to relative humidity above 85%).
Annual calibration is required if the sensor is exposed to relative humidity above 85%.

Inline v Insertion Flow Meters
Compressed Air Alliance offers two types of thermal mass flow meters – inline (or in-line) flow meter and insertion flow meter. Both flow meters (inline and insertion style) have a streamlined sensor tip which ensures minimal impact on gas flow while maintaining accuracy over a wide flow range.
Inline Flow Meters
- Inline flow sensors include a section of pipe as part of the flow meter. Threaded pipe sections are available from DN15 to DN50. Flange pipe sections are available from DN15 to DN80.
- Inline flow meters are best suited to permanent installations as you will need to cut out a section of pipe to install the flow meter. You will also need to turn off compressed air while you install the inline flow meter.
Insertion flow meters
- Insertion flow sensors are inserted into the pipe through a valve. They can be inserted under pressure so you don’t need to turn off your compressed air system during installation.
- Insertion flow meters are best used for permanent and temporary installations.
- For information on the Insertion flow meter, refer to the Thermal Mass Flow Meter page.
