Jed,
It strikes me as highly unlikely that whoever chose the flow meter (Penon?) would not talk to the manufacturer for advice on which model to get. I notice their catalog does not specify a minimum rate and with flow meters they generally run slower than they should below the bottom of the scale. As for the stain marks, without actually seeing them, I doubt they mean much.

    There are 2 products on this page, with very similar
    specifications, mp130-nc-80NC has nearly the same exact
    specifications, save for the minimum volume. IH is probably
    blowing some hot air to cause confusion in the  case.


Daniel, get a grip! At long last, Get A Grip. The guy who wrote Exhibit 5 is an expert engineer. He was _looking at the flow meter_. He quoted the numbers on the faceplate! He wrote:

"The Apator PoWoGaz’s device label clearly states that the unit has a minimum operational flow rate of 1.6 m3 /hour."

He did not write that to "cause confusion." Penon never answered him. It is case closed.
