Press
È
to
MinLvl
. Minimum level threshold. When the fluid “head” drops below
MinLvl
the flow
measurement is forced to zero.
MinLvl
can be set between 1” and 6” (25.4 and 152.4 mm) above
LvlOFFSET
setting.
Press
È
to
MaxLvl
. Enter the maximum expected level in your application. If the maximum level is
unknown, enter an estimated value, e.g. 6 ft.
Note:
MaxLvl
entry is only required to calibrate the level at 20mA output and to set the maximum
level measured in
LVT
logging mode.
MinRg
/
MaxRg
menu items will only appear in the calibration menu with optional PZ12-LP non-
contacting ultrasonic sensor.
MinRg
- is distance from the optional PZ12-LP
sensor to the highest water level (must be
³
8"/203
mm). Use
È
and
Ç
to enter the minimum range.
MaxRg
- is distance from the PZ12-LP sensor to the
zero water level (must be
£
12'/3.66 m).
Press
È
to
Damping
. Default setting is 2% to allow quick set-up of the instrument. 20% should be
ideal for most applications. Increased damping (up to 99%) slows the AVFM-II's response to turbulence
and will smooth the display and outputs under turbulent conditions. Decrease damping to minimize
response time for fast level or velocity changes. Minimum setting is 0%.
