Siemens SITRANS F FUH1010 Series Operating Instructions Manual page 65

Section 1
However, assume that the liquid's sonic velocity is very well known and is actually 1377
m/s. Press the <Right Arrow>. Note that an "equal sign" appears before the displayed
sonic velocity. Type [1377] and then press the [ENTER] key.
NOTE: As your 1010BX metering experience with various liquids evolves, your knowl-
edge and confidence regarding their sonic velocities will grow. If the Estimated
Vs and Measured Vs at site are different, as in the example on the previous
page, consider it a warning that something about the installation may be incor-
rect. Recheck transducer mounting geometry (e.g., Are they axial, diametrical
and spaced correctly?) and your pipe data and re-install. On the other hand,
when the Measured Vs conforms to the Actual Vs, your degree of confidence in
the correctness of the installation and the meter's intrinsic calibration perfor-
mance should be high.
This commands the meter to re-calculate its timing parameters to accommodate the new
sonic velocity setting.
