Flowrate Calibration and Calibration Tables

Flowrate Calibration Methods
SITRANS F 1010 equipment provides three ways to condition the calibration performance of
its flowrate output: Intrinsic (factory set), Kc, and Calibration Tables 1 through 3. Access to
these calibration options is found in the [Calibrate Flowrate] menu cell and the three [Calib.
Table] menu cells of the [Span/Set/Cal] menu.
Intrinsic
When selected, the flow meter uses no slope adjustment at all. Output data is still zeroed
and corrected for Reynolds number, but no slope adjustment is imposed on the flow meter's
flow register.
Some applications may require an output adjustment to match an official external reference.
The [Calibrate Flowrate] menu allows you to select a calibration mode. The right-hand
column shows the active calibration mode. You can select Intrinsic (factory) and Kc (Slope
Correction) Calibration. Selecting either of the external calibration modes will not eliminate
the Intrinsic (factory) calibration. You can use this menu cell to switch between Intrinsic and
Kc at any time.
Kc Calibration
For most applications, the measured flow range produces a linear meter response.
Therefore, the Kc (slope correction) calibration is the preferred method since it only requires
a single correction factor for all the flow rates encountered.
Note
Changing the calibration can cause profound changes in flow meter operating
characteristics. Use only the most respected flow standard to obtain a correction factor. The
percentage entered must provide an accurate and consistent shift across the entire flow
range anticipated for the application.
