§ 5 Measurement of Air Flow FLOW RATE Mode
CLIMOMASTER features an accurate Flow Rate Mode which
corresponds to the industry measurement standards such as
ASHRAE.
SINGLE FLOW RATE Mode
This mode is useful for performing a measurement of the airflow of
duct (i.e. a duct traverse). Following the steps listed below, you
can program Climomaster with the following parameters:

Sampling Time: The instrument will take a sample at the end
of this entered sampling time. Example: if you setup a
sampling time of 10 seconds, Climomaster will wait 10
seconds and then take a measurement. If you are taking
multiple samples, it will wait 10 seconds between each one
before taking the next sample.

Number of Trials: this is the number of samples you wish to
collect from a single point in the traverse.

Number of Points: this is the total number of points in the
traverse.
In single mode, the average, maximum and minimum values from
all points will be calculated. The instrument will record the average
from each point as well as providing a final average of all the points
in the traverse.
The value of each point is
recorded as the average of
TRIAL(1) to TRIAL(N). This
value
(for each individual point) is stored
in the memory.
To take an accurate measurement of the airflow of duct, you need to figure
out the average velocity of air inside the duct and the area of the cross
section of the duct.
TRIAL(1) (2) (3) ……(N) TRIAL(1) (2) (3) ……(N) TRIAL(1) (2) (3) ……(N)
Time needed to measure a point…Sampling Time X N (Number of Trial)
Value at point 1 Value at point 2 Value at point M
POINT(1) POINT(2) ……………… POINT(M)
POINT(1): avg(1)＝ΣTRIAL(N)／N
POINT(2): avg(2)＝ΣTRIAL(N)／N
・・・
POINT(M): avg(M)＝ΣTRIAL(N)／N
<Result>
 Average (AVG): AVG＝(avg(1)+ avg(2)+ ････+avg(M))／M
 Maximum (MAX): MAX＝ Maximum value from avg(1) to avg(M).
 Minimum (MIN): MIN＝ Minimum value from avg(1) to avg(M).
