It's what they use whenever they need to know the flow rate of a fluide.

The version in cast iron, or machined steel cost a fortune and price can easily skyrocket in the thousand $, let alone the aerospace field that might go even in the 10k$.

Our school couldn't afford venturi due to highcost, and, I saw the potential for small laboratory project using compressed air tool, blower testing, etc. Instead of spending stupid amount of budget on some items that might be used one or twice.
