4.2.2 360 Velocity
The 360 Velocity measurement tab has a grid containing 15 pos-
sible measurement points. The measurement points are acti-
vated and deactivated by selecting or deselecting the appropriate
check box. To save the measurement settings, click the “
Apply
”
button (F9).
As the LaserFlow begins to take readings, the grid becomes pop-
ulated with a velocity reading and time stamp for each active
measurement point (points where a valid reading could not be
obtained will display the word “invalid”).
Prior to operation, the LaserFlow sensor must be set up for mea-
surement using the 360 Velocity grid. Refer to Section 4.3
Sensor Positioning and Adjustment
When the
Positive Velocity
option is “true”, the LaserFlow will
not attempt to determine flow direction and negative readings
are discarded in the average velocity calculation. Selecting this
setting will save power. The default is “true”.
When the Positive Velocity option is “false”, a second velocity
measurement is taken to determine the direction of the flow.
