Xylem Magflux Electromagnetic Flow Meter - Manual (Page 64)

64 EN 3.05 MagFlux Manual 1212
Electromagnetic Flow Meter
Using the factory setup MagFlux ® returns to default mA settings corre-
sponding to the chosen MagFlux ® flow sensors Q
min
and Q
max
.
The mA output is an active output, and the maximum load is 800 Ohm.
The upper limit for the mA output is 20,5 mA
3,75 mA indicates the mA output is not in use
3,5 mA indicates flow under 4 mA level
20,5 mA indicates flow higher than 20 mA level.
The 20 mA maximum output is rounded up to the nearest round figure.
Example: The maximum flow of 17.676 m
3 /h for a DN25 is rounded
up to 20.000 m 3 /h.
Flow Forward
The mA signal provides 4 mA at zero flow and 20 mA at Q
max
in the for-
ward direction.
