  • Q:

    We have got one and wondering how to calculate the volume flow rate from the anemometer reading and which open area you have to consider. The 4" diameter or 4" diameter minus the inner graduated puck?
    We made a collar around the anemometer.
    Asked on 7/9/2013 by Amir from Calgary

    • STAFF EXPERT

      A:

      The volumetric flowrate will depend upon the diameter of the tube the anemometer is placed in or obtaining a reading from. Putting a collar on a unit and placing it outside is not going to give you the volumetric reading of anything except the volume of air through the collar.

  • Q:

    Do you have an A/4-4 instrument which measures in cubic meter per second and not in cubic feet per minute?

    • STAFF EXPERT

      A:

      Unfortunately the only version of this is the version available as catalog number 32044-81. There is not a direct dreading version available for cubic meters per second.

  • Q:

    Hi! Can it output data direct to a PC via a com port? Is it available for direct CFM reding?

    • STAFF EXPERT

      A:

      This unit does not feature a computer output and they are not available for a direct CFM reading. CFM measurements require use of the correction factors and the measurements of the test area.

  • Q:

    My anemometer is 8 ft from the ground. I understand the weather service and others place theirs at 7 metres (23 ft). Am I getting correct wind speeds, or do I need to do a calculation?
    Thank you.

    • STAFF EXPERT

      A:

      Having the anemometer 23' up meets NWS standards, 8' does not. Wind speed at low levels like 8' is reduced due to friction effects, variable terrain and wind shadowing from trees, bushes, buildings and so forth. For the most accurate report, you should mount the anemometer up high, if feasible.

  • Q:

    How do you use the anemometer to get a CFM reading. Thanks
    Asked on 11/10/2011 by AJ from Lyons KS

    1 answer

    • STAFF EXPERT

      A:

      Directions for determining cubic feet per minute with Item 32044-81, are as follows:
      Take a 60 second reading at the face of the opening. For larger areas it is recommended to take several readings at various locations along the opening and average these readings. Apply the correction factor to your reading from the supplied sticker. Multiply your corrected feet per minute reading times the square footage of the opening to obtain your cubic feet per minute reading. For testing open air spaces, it is recommended to divide the cross section into square foot areas, taking a separate reading for each area. Average all these anemometer readings to obtain a single reading for the open space.
