Vortex flow meter for natural gas

Flow Q&A

We need a natural gas flow measurement, and I'm wanting to use a vortex flow meter! The maximum flow rate is 400 cubic meters per hour at 20 degrees Celsius and a maximum pressure of 4 bar. Should I choose the vortex?

Expert’s answer: Vortex flow meter for natural gas

You can definitely use a vortex flow meter for natural gas, but it won’t provide the best accuracy, given your process information. You’ll need a pressure flow meter for this flow measurement.

If you want the best accuracy and you have a little room in your budget, you should consider a Coriolis flow meter. You’ll get better accuracy than with a vortex and you won’t need a pressure transmitter. It’ll probably cost more than other options, though!

You can scale out your flow meter using the Applicator from Endress+Hauser or the Toolkit from Emerson. These tools will help you find the best device for your application.
