SUMMIT 8800 STREAM CONFIGURATION 06
6 .2 .4 .2 Pulse Input API 5 .5 level B to E
Define the preference for serial or pulse input and the pulse input setting for API 5.5 level B to E
if used

Primary measurement This option defines whether the serial link or the pulses will be used as a
primary measurement. The other will be used when the primary fails. Off
course only one of them can be used also: the other will not be connected..
Frequency method Defines if the pulse corresponds with mass or volume. All Coriolis meters
measure mass, they can also calculate the volume. Though less accurate,
some users prefer this as their company standard
Impulse factor The K-factor or impuls factor for the HF pulse. The total number of pulses
corresponding to one unit of flow.
Frequency input API 5.5 level B to E.
Turbine minimum
frequency
Low cut-off frequency. This is frequency below which the flow will be
considered 0.
Blade ratio Ratio between the two frequency inputs. For one input set to 0. For two
identical frequency inputs set to 1
Preset K Factor LF The K-factor or impuls factor for the LF pulse. The total number of pulses
corresponding to one unit of flow. (Gas only).
