Correction table Current/flow
Frequency/K factor
Flow/factor
Should the flow curve of the flow measurement device deviate
from the ideal (linear or squared) this can be compensated for
by set up of the correction table. The parameters in the table
are dependent on the selected flow measurement device.
•
Analogue signal
Up to 15 pairs of values (current/flow)
•
Pulse signal
Up to 15 pairs of values (frequency/k factor or
frequency/pulse value)
•
Differential pressure
Up to 10 pairs of values (flow/factor)
For details see ’Correction tables’ in the appendix.
Pipe data Pipe internal diameter
Diameter ratio
Input of the pipe line internal diameter.
Input of the diameter ratio (d/D = ß) of the differential
pressure device. This value will be supplied by the
manufacturer of the differential pressure device.
!
Note!
Addresses are only active on differential pressure devices. On
standard pressure devices only enter the pipe internal
diameter.
