The default value for each of these new parameters is 0.0. A value of zero effectively disables the pres-
sure and temperature pipe volume compensation routine. When entering a value for the thermal expan-
sion coefficient and modulus of elasticity, keep in mind that the numeric entry already includes an expo-
nent multiplier. For the Thermal Expansion Coefficient the multiplier is 10
-6
and for the Modulus of Elastic-
ity the multiplier is 10
6
.
Typical values for each parameter are shown below:

PIPE CONFIGURATION
The [Pipe Configuration] menu cell in the Pipe Data menu presents a list of descriptions of piping configu-
rations that could affect the flow profile characteristics (such as “Single Elbow”). Examine the option list.
Selecting a piping configuration that closely approximates conditions at or near your mounting location
allows the flow computer to compensate for the effect of upstream piping on flow profile. The number of
diameters between the upstream configurations and the transducer installation can be numerically en-
tered via the [Anomaly Diams] menu cell.
