2.4.1 HOW TO SELECT A TRANSDUCER MODEL
Use the [Transducer Model] menu cell to define the type of transducer for use with your
application. This allows the computer to adjust its transmit/receive functions accordingly.
You can choose from either the [1011 Universal] or [1011H High Precision] transducer lists, or
from a list of [991 Universal] models. You should consider using high precision transducers
for extremely critical applications. The system default is [1010 Universal]. If this suits the
application, bypass this menu cell by pressing .
After selecting the meter type from the Main Menu, press and scroll down to Pick/Install
Xdcr. Press again to highlight [Install Path].
To select Install Path:
Press to access the [Install Path] option list (Path 1 or 2).
Use keys to select the path number.
To store selection press .
To select a Transducer Model:
To access the [Transducer Model] option list press
To move the cursor to the required Transducer Model press
To store your selection press
2.4.2 HOW TO SELECT A TRANSDUCER SIZE
When you move the cursor to Transducer Size, the highlighted prompt at the top of the
display screen shows a list of recommended transducer sizes. For example, [Recom-
mended Xdcrs: D3,D2,D1,C1,C3] . The Interface Detector generates this list automatically
based on your pipe and your application data entries. The left-most transducer size (e.g.,
D3) is the primary (most appropriate) choice. The rightmost transducer (e.g., C3) is still
acceptable (but the least desirable) choice. Since these are simply recommendations, not
requirements, you can override the Interface Detector and use any size, as long as the mount-
ing method accommodates the pipe’s diameter. The Interface Detector shows that your selec-
tion is acceptable if it is able to calculate transducer spacing (Ltn).
To select a Transducer Size:
To access the [Transducer Size] option list press
To move the cursor to the desired Transducer Size press
To select the transducer press
2.4.3 HOW TO SELECT A TRANSDUCER MOUNT MODE
The Interface Detector recommends using the transducer Direct mounting mode. In al-
most all cases it will be the Direct Mode, since this is the most desirable configuration. Direct
Mode mounting produces a stronger transducer signal and requires less mounting length than
