Proper positioning of the LaserFlow Ex sensor is critical for
optimal velocity measurement. In center position, the laser beam
must strike the flow stream precisely in the center.
The beam automatically moves to the top center position.
Select Laser On and press Enter. This will keep the laser beam
on continuously for 10 minutes or until Laser Off is selected,
allowing the beam to be used for fine-tuning the sensor's
position.
Note
When sensor positioning is completed, securely tighten all
mounting hardware.
Once the LaserFlow Ex sensor is installed over the flow stream,
some installations may only require the center laser position for
velocity measurement.
For installations requiring multiple measurement points, the
next step is to determine which points will be used. To do so,
activate all 3 points and wait for all of them to display their
readings. This process may take up to 2 minutes.
Each point will display a velocity reading and time stamp, or
"Invalid." Deselect "Invalid" and undesired points. The fewer
points selected, the less time required to complete one velocity
measurement.
