Instruments for measuring low-pressure natural gas
Thread Content
Experts, I’d like to ask what are the best instruments for measuring natural gas. Thank you!
If it’s flow rate, then of course it’s a mass flow meter
This question is such that it’s impossible to answer even if you wanted to. . . . Are you measuring flow rate, pressure, or temperature? Do you need imported or domestic products? What is the required precision? How can one answer without explaining any of this?
The original poster’s question is too vague; there’s nothing at all, no specific requirements either. The selection of a flow meter is closely related to the operating conditions at the site as well as the performance requirements for the instrument. Without relevant parameters and specific requirements, it is impossible to provide a reasonable recommendation.
Low pressure? What’s the data volume? Generally, mass flow meters are used for small systems, while ultrasonic sensors are used for larger ones.
Leak detection can be done using a pump-type leak detector
Mass flow meters are quite accurate, and they can also transmit information such as density and temperature over long distances. Recommended.
For use with main pipes and by natural gas companies for metering, positive displacement flow meters are generally employed, such as Roots flow meters and turbine flow meters, with automatic temperature and pressure compensation. If not, orifice plates can be used for large diameters, while vortex flow meters are suitable for small diameters. Mass flow meters are relatively expensive, which is a waste!
Low-pressure natural gas flowmeters do not require mass flow measurement
