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

Section 2
The default specific gravity setting is 1.000. The flow computer uses the liquid's specific gravity to form
a multiplier for the conversion of volumetric flow to mass flow. Mass flow appears (in selected units) on
the display screen. Density (SG) (as it applies to this system) is defined as the ratio of the mass of this
liquid to the mass of an equal volume of water at 20
To edit the Density SG setting:
To activate numeric entry press
Use the numeric keys to type the Density SG value.
To register the data press

2.3.2 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, -30
perature range of our standard 991 or 1011 series transducers. The other selections provide higher
0
upper limits of 375 F and 450
If you know that the pipe temperature will exceed 250
use 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

2.3.3 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 mount-
ing 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 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.
