the regularity and symmetry of the flow. The greater number of
paths is, the less the dependence of the measurement on the flow
velocity profile will be.)
Sizes and Flowrates
Faure Herman offers 10 standard diameter versions, from 4"
(DN100) to 24" (DN600), except 22". See in Appendix I the
dimensions and weight of each of these counters.
Standard K-factors
The factory set K-factors are, depending on the size:
FH8500 diameter Pulses / m3 Pulses / barrel
4" (DN100) 32 000 5 000
6" (DN150) 16 000 2 500
8" (DN200) 8 000 1 300
10" (DN250) 6 000 1 000
12" (DN300) 4 000 650
14" (DN350) 3 000 480
16" (DN400) 2 200 350
18" (DN450) 1 600 250
20" (DN500) 1 400 220
24" (DN600) 1 000 160
Remark: For a given size, the recommended K-factor has been adjusted to
provide the best repetability of the measurement.
Working modes
The FH8500 can operate in two modes: custody transfer mode
and non custody mode
•
In custody transfer mode, only the parameters which have
no influence on the measurement (display units and units
used for the 4-20 mA outputs and the alarms, parameters
concerning the different inputs - outputs…) can be
modified.
