  My code is wrong in the driver for wind speed or the sensor is not good enough at such low speeds.   Measured with an anemometer Exhaust velocity  6.864  m/Sec mean  Mass Flow  0.121296892 m/Sec3  That's  7.2778  m/Min3  Therefore it is extracting 165m3 in 23 minutes That what I originally wanted 8 m/Min3 woo hoo

  Measured Mass Flow in Exhaust Port of ERV  4.4 mS through 15cm duct = 0.0777 m/sec3  so 165m3 is removed in 35 Minutes DAS Reports 0.102 mean with the pitot tube in the exhaust duct
