Make sure to make a tight connection by pushing enough to avoid measuring secondary air.
9. ADDING OF MEASUREMENTS Thanks to the zero pressure compensation of the FlowFinder mk2®, it is possible to measure the air flow at part of the diffuser. Because the FlowFinder mk2® actively compensates its own resistance, the flow through the other (free) part of the diffuser will not or hardly be influenced.
