firm with ENTER to start the sensor
positioning procedure. When both
channe s have been activated, the
procedure for CH2 fo ows the one of
CH1 .
Senso Positioning Sc een
• Mount the transducers with the suggested spacing between the
sensor heads. This distance has been determined by the f ow-
meter on the basis of the entered parameters.
• Use the disp ayed number of passes to insta the sensors on the cor-
rect side of the pipe (see pictures 3 and 4).
• Observe the upper bar (signa -to-noise ratio) and ower bar (signa
qua ity). These shou d be both fi ed to about the same eve with a
fi ing eve of around 1/3 or more desired.
• Even number of passes: Both sensors on same side of pipe (see pic. 3).
• Odd number of passes: Sensors on opposite sides (see pic. 4). Con-
firm with ENTER . The second channe can now be prepared by
se ecting Setup Wizard CH2 .
Step 3: Quick Sta t Menu and Setup Wiza d (continued)
• Use the cursor between the two signa bars for the fine adjustment
of the sensor position. With correct pipe parameters entered and
the sensors mounted at the suggested spacing, the mark shou d be
near the centra indication ine (see three ines be ow the bottom
signa bar).
• If the mark is to the eft-hand side of the centra indication ine, the
sensors are too c ose to each other. If the mark is to the right, the sen-
sors are too far apart. S ide one sensor carefu y a ong the pipe to
bring the mark into a more centra position. Measurements can be
obtained when the mark is between the eft and right indication
ine. Press ENTER to start measurement.
