The device is pre-programmed for common PMD flow calculations. If your PMD is not listed,
select the appropriate Universal Flow Calculation.
Associated parameters Maximum Head (2.13.4.2.) (Page 243), Maximum Flow (2.13.4.3.)
(Page 243), and Zero Head (2.13.4.5.) (Page 244) may be scroll accessed. If Sensor Mode
(2.1.3.) (Page 163
) = Flow rate in open channel, this value is preset to
1
. If Sensor Mode
(2.1.3.) (Page 163
) is not set for
OCM
, it is preset to
0
.
8.6.13.3
