The easiest way is to describe the contents of the pipeline, its temperature and pressure, the pipe size and any other relevant data, and then let the various suppliers make you offers.

You'll need the following information so that a manufacturer of flow meters can assist you in making a recommendation for your application:
1. Pipe size
2. Maximum estimated gas flow rate
3. Minimum flow rate you would like to measure
4. Turn down ratio
5. Repeatability
6. Accuracy
7. Gas temperature
8. If this is liquid gas (and not natural gas) what is the specific gravity & viscosity?
9. Gas pressure (min/max)
10. Available upstream & downstream pipe diameter (this is critical for proper flow measurement)
Some things to keep in mind:
- Why are you trying to meter your gas? Are you using this for bill verification? Flow control?
- Will you be able to take the gas line out of service for inspection, calibration, replacement? If you can't, then an orifice plate might not be the right meter for you. You may want to consider an insertion type flow meter.
The following link discuss the various types of flow meters and things that you need to consider when selecting a flow meter.
