What type of flow meter can be used in the synthesis of hydrochloric acid to effectively control the chlorine-to-hydrogen ratio?

In the production of synthetic hydrochloric acid, a chlorine-to-hydrogen ratio of 1:1.05 is required; however, this ratio is difficult to maintain in actual production. I would like to know what flow control methods people use to achieve this standard? # ， ， &
We use orifice plate flow meters, and with proper selection, they should be able to serve for monitoring production.
Production adjustments can also be made in conjunction with the purity of hydrogen chloride.
The purity of chlorine used in our production is generally around 60-80%. The processing method involves ignition beneath a two-in-one furnace. So, if adjustments are made based on the purity of hydrogen chloride, what would be the approximate percentage of hydrogen chloride gas after passing through the graphite cooler? Thank you!
It’s better to use a vortex-type flowmeter for measuring hydrogen flow. My previous workplace also used vortex-type flowmeters, and they were quite accurate
