Can vortex flow meters be used for trade metering of compressed air?

It is necessary to check whether the flow measurement is intended for use with customers; if so, then an vortex flow meter can definitely be used. However, many customers are reluctant to use vortex flow meters, and this is mostly due to errors made during the selection process – the wrong type of vortex flow meter was chosen, which results in significant measurement errors or no data being available. Secondly, compressed air metering requires the output of values on standard conditions; most vortex flowmeters use external temperature and pressure sensors, which not only increase costs but also make installation complicated and maintenance difficult. The Hefei Comajet VFM60MV integrated temperature and pressure vortex flow meter features a temperature and pressure sensor built into the flow meter itself; this design not only reduces the number of installation steps but also makes the device less prone to damage. It has significant advantages in measuring compressed air: not only can the lower measurement limit reach 2 m/s, but the range ratio is as wide as 1:35. It employs a proprietary dual-probe technology to effectively eliminate interference caused by vibrations. Moreover, it is cheaper compared to other flow meters, making it an ideal choice.

This involves an issue of mutual agreement; accuracy and other aspects require approval from both parties. Confirmation from the other party is needed.

Judging from the accuracy provided by the manufacturer, there is no issue, and it is also used for trade settlements.................

Can compressed air also be sold for money? Which wealthy user is it? Can’t we just buy any old air compressor? If the usage is high, why not invest in an air compressor room yourself?

Silly, there are many types of compressed air; nitrogen, oxygen, and hydrogen all count as such

I heard it’s used in the energy renovation of air compressors; doesn’t that involve trade metering? :D

It depends on the precision requirements; it should be fine. The precision requirements for compressed air measurement are likely not very high~

Both parties agree that an authoritative third-party inspection report confirming compliance and meeting a 1.5-grade accuracy standard is sufficient

What can be used is to try to avoid installing it in places where there is a lot of vibration
