(5) Squawk (Effective only when setting to
HART 7)
This feature can be used to identify the
communicating transmitter by remotely causing
LCD to display the particular pattern as shown in
the Figure 3.3.
“SQUAWK” continues for approximately 15
seconds, then is released automatically.
Enter the larger number to “Change number of
squawks to make” in order to prolong the duration
of squawk indication.

3.3.14 Basic Flow Calculation (Basic mode)
In the case of Basic mode, flow operation and
density compensation are performed conventionally
with the flow factors manually input.
The flow rate is calculated using the constant flow
factor.
Density is compensated as follows according to the
selection of gas or liquid.
Gas: Compensation as ideal gas by
temperature and pressure.
Liquid: Compensation by temperature.
There are an automatic compensation mode and
basic mode in the flow calculation, and either is
selected in the Flow Calc Mode parameter.

according to the procedure of Table 3.2.
FSA120 (FieldMate FlowNavigator) can configure
both automatic compensation mode and basic
mode. For detail, refer to the User’s Manual of
FSA120 FieldMate FlowNavigator (IM 01C25R51-
