F-2600 & F-2700 Vortex Flow Meter Manual 02/15 - 0808-7 / 19204 Page 106

4. The vortex coefcient Ck may be incorrectly set. The Ck is a value in the equation used

to determine if a frequency represents a valid vortex signal given the uid density and

signal amplitude. In practice, the Ck value controls the adaptive lter, , setting. During

ow, view the f and  values in the rst level of the hidden diagnostics. The  value

should be approximately 10-20% higher than the f value. If you raise the Ck setting in

the Calibration Menu, then the  value will increase. The  is a low pass lter, so by

increasing it or lowering it, you can alter the range of frequencies that the meter will

accept. If the vortex signal is strong, the  value will increase to a large number – this is

correct.
