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 flow 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. We usually
recommend these transducers for custody transfer, leak detection or nuclear power applications. The
system default is [1011 Universal]. If this suits the application, bypass this menu cell by pressing the
<Down Arrow>.
To select a Transducer Type:

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, [Recommended Xdcrs: D3,D2,D1,C1,C3].
The flow computer 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 right-most trans-
ducer (e.g., C3) is still acceptable (but the least desirable) choice. Since these are simply recommenda-
tions not requirements, you can override the flow computer and use any size, as long as the mounting
method accommodates the pipe's diameter. The flow computer shows that your selection is acceptable
if it is able to calculate transducer spacing (Ltn).
