Gas flowmeter selection
Thread Content
I want to measure the volumetric flow rate of a mixture of hydrogen and carbon dioxide; under normal temperature and pressure, this rate is around 10 m3/h. What type of flow meter would be suitable and safe for this purpose?
For clean gases, a vortex flow meter is sufficient; pay attention to the flow velocity.
For vortex flowmeters, make sure the pipeline is properly fixed – there should be no vibrations. I’ve used Yokogawa and Zhejiang Diyuan models before, and they worked fine
It’s a differential pressure type, right? A wedge flow meter will work; what is the diameter of your pipe? Ensure the flow rate meets the requirements
A metal rotameter can be selected~~
For flow meters, it is best to use those of the vortex street, orifice plate, and throttle device types; opt for split-type models that are powered by a 24V power supply or batteries
