Pressure Units.
Differential Pressure.
Flow Type-Volumetric or Mass Flow.
Flow Rate Units.
Flow rate at upper range value of Differential Pressure.
Present value of Flow rate.
The block supports the following modes:
•
AUTO (Automatic)
•
OOS (Out of Service).
In AUTO mode, the FTB constantly calculates the volumetric flow
rate based on the equation described and updates the values
based on change in ΔP of the flow units. In OOS mode, no
calculation is done; and the rated flow value can be changed.
The block goes out of service:
•
When target mode is changed to OOS (or)
•
RB is OOS (or)
•
PRESS_BASIC is OOS (This is done because flow rate is
calculated from DP and is meaningless when PRESS_BASIC
is OOS).
The block supports standard block alarms (see section 3.2).
