As indicated in the above prompt, the Model GF868 flowmeter can take measurements in two different ways
Skan
is a low resolution technique for locating the acoustic signal and for high velocity measurements. It is more
robust in a noisy environment than the Measure technique.
Measure
is a more precise technique best used for low velocity measurements.
If
Skan
is selected at the next prompt, the instrument uses this technique exclusively. However, if
S/M
is selected, the
meter uses
Skan
to find the acoustic signal and then tries to use the
Measure
technique for a more precise measurement.
Proceed directly to the next section to program the
SYSTM
submenu.
