20mA Flo
[5V Flo]
[OFF]
Press
and enter the flow rate value for 20mA.
Note: Analogue output can be selected as 4-20mA or 0-5V in Special Functions.
4mA Flo
[0V Flo]
[OFF]
Press
and enter the flow rate value for 4mA.
Lvl Offset
Optional for QZ02L sensor (use for mud or silt conditions).
Press
and enter an offset to level measurement. Set to 0.00
when sensor mounted on floor of channel. When sensor is
mounted above the floor of the channel enter the distance
between channel floor and bottom of sensor. Maximum offset
is ± 36” (914 mm).
Note: 4mA is not affected by
Lvl Offset
settings. 4mA
is the bottom of the channel or pipe.
Min Vel
Press
and enter a minimum velocity cutoff. Forward and
reverse velocities less than
Min Vel
will be forced to zero.
Damping
Increase damping to stabilize readings under turbulent flow
readings or to reject spurious level readings. Decrease for
faster response to changes in flow.
Press
from the
Calibration
display to return to Menu Selections.
