How To Select A Pipe Temperature Range; Pipe Configuration - Siemens SITRANS F Instruction Manual

Section 2
Note that the flowmeter computes energy taking into account the signs of both flow and Td. Thermal
energy applications are expected to exhibit positive liquid flow rates from the supply to the return loca-
tion. You may use either Flow or Energy deadbands (see next page) to prevent "nuisance totalization"
during non-flowing periods.
To edit the Service setting:
To move from [Application Data] to [Service] press
To move the cursor to [Service] menu list press
To scroll the list to move to desired Location press
To register your choice press

2.3.4 HOW TO SELECT A PIPE TEMPERATURE RANGE

This menu cell informs the flow computer about the expected temperatures that the transducers will be
subjected to during operation. The default setting, -40
ture range of our standard 991 or 1011 series transducers. The other selections provide higher upper
limits of 375 0 F and 450
If you know that the pipe temperature will exceed 250
this menu cell to select the appropriate range. This will allow the flow computer to restrict its transducer
recommendations to the appropriate environmentally rated types.
To select a temperature range:
To access the option list press
To highlight the desired range press
To register your selection press

2.3.5 PIPE CONFIGURATION

The [Pipe Configuration] menu cell in the Application Data menu presents a list of descriptions of piping
configurations 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 nu-
merically entered via the [Anomaly Diams] menu cell.
To select a Piping Configuration:
To access the option list press
To highlight the desired piping configuration press
To register selection press
The default pipe configuration (Fully Developed) wll cause the flowmeter to use the conventional Reynolds
Compensation Table when compensating for liquid flow profile behavior.
