The thermal mass flow meter can measure in pipe sizes as small as ¼ inch and as large as 36 inches, though the pipe size may dictate the meter styles (in-line versus insertion flowmeter).
Pipe Sizes and the Thermal Mass Flow Meter
The Sage Metering thermal mass flow meters can accurately measure pipe sizes as small as ¼ in (6.35 mm) and as large as 36 in (914.4 mm). However, when measuring exhaust gases in ducts, the end-user should consult with the factory first. Additionally, if you have an application for pipe sizes outside the ¼ inch to 36-inch range, consult with our factory first before ruling out using a thermal mass flow meter.
In-Line or Insertion style
The size of the pipe may determine whether or not to use an in-line or insertion style meter.
- For pipe sizes, less than 1 in or 25.4 mm, in-line meters are required since there are currently no acceptable insertion probes for the insertion model.
- For pipe sizes between 1 in (25.4 mm) and 4 in (101.6 mm), both the in-line or insertion style meters may be used.
- For pipe sizes greater than 4” (101.6 mm), select insertion style meters when designing your flow meter.
What is the difference between insertion and in-line flow meter? That frequently asked question is addressed in What are the Benefits of the Inline vs. Insertion Flow Meter?
Have you checked out the Build-a-Meter?
When designing a Sage thermal flow meter on our Build-a-Meter tool, keep pipe-sizes in mind. Do not use insertion meters in pipe less than 1”, and don’t use in-line meters for pipes greater than 4”. Also, consult the factory for the ideal probe sizes for insertion meters and remember to inquire about the proper mounting hardware (which can be provided by Sage).
