Submerged Area Velocity Sensors
2. Place the sensor flat on a table top or floor with the sensor (the plate with
holes) facing down onto the surface (Figure 45).
3. Press any key.
4. Place the sensor face up in the bucket or liquid. Tap lightly to remove air
bubbles. If these bubbles are not removed you can receive false readings
from the sensor during calibration (Figure 45).
Always check the Level Adjust when
reinstalling the flow meter following
a calibration. (See Keypad
Description on page 19.)
5. Place the sensor face down under at least 7 in. (20 cm) of water. Make
sure the water surface is calm and the probe is stable.
6. Press any key.
7. Measure the depth from the bottom of the bucket to the surface of the
water and enter the value using the numeric keypad (Figure 45).
8. Press the
ACCEPT soft key.

4.13.3.1 Important Guidelines for Submerged Area/Velocity Sensor Installation
Installing the submerged area/velocity sensor follows the same instruction as
the velocity-only sensor. Refer to Installing the Velocity-Only Sensor in a Pipe
