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.
