Urgent! Urgent! Urgent! ! Ultra-low flow measurement of concentrated sulfuric acid
Thread Content
To measure the flow rate of 98% concentrated sulfuric acid, which is very low, ranging from about 8 ml/min to 25 ml/min, does anyone know what type of flow meter can be used for this purpose? Or which method can be used to measure it?
There must be some. The flow rate on the chromatograph is much lower than this. As long as you find the right manufacturer and the right product, it will work. If that doesn’t work, maybe we can remove the components from the chromatograph and use them instead. It’s just Hai Gui; I’m not sure if you’re willing to do that.

I’ve used online sulfuric acid concentration detectors, and they’re useless; they seem to be nothing more than decorations, plus they’re extremely expensive
I wonder why it’s just a gimmick – are the measurement values inaccurate, is there a delay in measurements, or is the failure rate high?
You can take a look at the pinned post in this version; there’s an option to request free connections, or you can search on Baidu for “Daxueshi””
This is from a certain paper. A micro metering pump is used. It can serve as a reference for you.
