Not to push any particular product or manufacturer, but several of the hose equipment manufacturers sell combination Flowmeter - Ventura setups for testing PRV's. One example is the model 9415 from Guardian Fire Equipment, Inc. http://www.guardianfire.com/products/sprinklertest/9415Flowmeter.html# I personally have never used one so I can't tell you the plumbing involved.

The design engineer is not helpful and the installers have no clue of how to test them. Will you be able to describe how the actual test in done? I thought you also need to use a pitot tube, but how can this be done if you use a short piece of testing hose with one side connected to the drain riser and the other side just after the PRV.
