FlowFinder
made in holland
The new standard for air-balancing
"VALIDATING AND ADJUSTING VENTILATION SYSTEMS"
The FlowFinder mk2® is the successor of the well known FlowFinder 153, which has
proven itself as the benchmark for air flow measurements to balance mechanical air
supply and exhaust systems. The new FlowFinder mk2® is fully zero pressure compensated
in the range 10 to 550 m m
/hr (6 to 323cfm) and has a calculated compensation for its
3
resistance up to 850 m
/hr (500cfm).

    ‘validate’ or ‘adjust’. To change the default mode you have to go to the options menu. To do a measurement, hold the FlowFinder mk2® by the left and right round handles and place the instrument over the outlet or inlet you want to measure. Make sure to make a tight connection by pushing enough to avoid measuring secondary air.
  • Page 8: Adding Of Measurements

    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.
