3.6.6b Programming the placement
The Placement menu allows the user to configure the
mounting method of the transducers, based on the
Transducer and Pipe programming done as specified in
sections “Programming Menu Options” on page 60 and
“Programming the Transducer” on page 65.
1. Refer to Figure 75, select [Placement] and press [ENTER].
2. Program the [No. of Traverses] based on your transducer
installation and transducer configuration. Refer to Figure
73 for possible Traverse configurations supported in the
meter. Typically, a
two-traverse installation is used.
3. The [Spacing] shows the value calculated by the
XMT1000 for the correct distance between the
upstream and downstream transducers, based on your
programmed transducer, fluid and pipe data. This is
the physical spacing value that should be used when
installing your transducer clamping fixture on the pipe
(see Figure 74). When exiting from the [Channel x] menu,
the meter will display a message indicating that the
Physical spacing of the transducers need to be adjusted
to the value calculated by the XMT1000.
4. Adjust the physical spacing to value calculated by the
XMT1000.
5. Repeat section “Channel X Programming” on page 65
for all channels.
6. This completes the programming for flow
measurements. All further steps involve calibrating
meter for accurate velocity and sound speed
measurements. Exit programming by pressing [ESC]
until Save options are displayed on the menu. Highlight
[Save] or [Save and Logout] and Press [ENTER] to save
settings. The meter will not use the changed setting to
make measurements until the settings are explicitly
saved.
7. Make sure your pipe is full and there is no flow. Before
you proceed to next section “Programming Advanced
Channel Settings” on page 69, allow for a 5-minute zero
flow stabilization time.
Note: If your transducers need to be installed with a spacing
different than that calculated by the XMT1000, make sure
it is within 10% of the calculated value. Overwrite the meter
calculated [Spacing] value with installed Physical spacing.
