Yes, however precision flow meters in this range are very expensive, and many of them use brass or copper fittings which corrode in the presence of AgNO3. They usually run in the range of Liters / minute or CC/min, in ranges far above what I use.

At EK, I had the complete catalog of one of the large companies and had their precision flow meter kit with dozens of them in the kit. I used them for many projects, but finally dissolved a set with the wrong chemistry. I had to reorder several very expensive meters and learned that you need stainless points and balls. Some of mine were Dwyer IIRC.

This need for stainless increases the cost.
