Requirements for the installation pipe diameter of vortex flow meters
Thread Content
There is currently a pipe with an inner diameter of DN350, with flow from bottom to top; the medium is compressed air, and the maximum flow rate is 4500 M3/H. Is it possible to use vortex flow meters? Are there any requirements regarding the maximum pipe diameter for installing such meters? Or give some advice on which type of flow meter would be more suitable
What is the pressure of the compressed air? Is 4500 under operating conditions or standard conditions?
I don’t know how much work pressure you’re under, nor do I know if your maximum flow rate is in cubic feet per second. Screenshot of the Ganges vortex flowmeter. You can take this as a reference. There should be no problem.

When using a vortex flowmeter to measure gases, it can be installed in a vertical pipe, but it is necessary to verify the requirements for straight pipe sections as well as the available installation space on site. The maximum diameter of conventional vortex flow meters can reach 300 mm, and the applicable conditions must be calculated using specialized software. Pressure loss and accuracy need to be considered.
Flange-type vortex flow meters are generally smaller than DN250; if a vortex flow meter can be used, DN250 is sufficient, and the cost for imported ones is over 30,000.
There’s no need to use vortex flow meters; orifice plates are much cheaper
To determine whether measurement is possible, detailed operating condition parameters are required; it is preferable that the flow rate be expressed in standard conditions. Vortex flow meters can be used for air flow measurement, but given the current conditions, using a vortex flow meter is not the best choice. If your measurement point is on the main pipeline and located at the rear end of the gas storage tank, I personally recommend choosing a thermal mass flow meter; firstly, thermal flow meters are stable and reliable, and they offer a wide range of measurement capabilities. Second, it is easy to install – it can be done in just one hour. If problems arise in the future, it is easy to disassemble; no process shutdown or pressure reduction is required – disassembly can be carried out while the system is still under pressure. If you are interested in this area, feel free to contact me; I will be happy to help.
For DN350 vortex flowmeters, unless they are of the inserted type, thermal mass flowmeters can be used. You can contact me for details
If a straight pipe section is available, instruments such as vortex flow meters or Coriolis meters can be used, as this results in lower pressure loss; however, the pipeline in which the vortex flow meter is installed must not vibrate. An orifice plate can also be used; take into account that the pressure loss with an orifice plate is high, but its cost is low.
