3.4.0 FREQ. OUTP. F : set up frequency /
pulse output
3.4.1 FUNCTION F : Program the analog fre-
quency output
Select an output option using the key and press
to store:
2 DIR : Enables flow measurement in 2 direc-
tions (fig. D.7).
TRAN. TIME : Output signal is proportional to the
measured transit time of the acoustic
signal.
NOTE: This function requires:
- PULSRATE setting, Fct. 3.4.2
- PULSRATE at full flow, Fct. 3.4.3
- Transit time at full flow, Fct. 3.1.2
(see example in description of Fct. 3.1.2)
NO SIGNAL : Output signal indicates "signal loss".
OFF : No frequency output.
F/R IND. F : Output signal as flow direction indica-
tion, 0% at + flow direction and
100% at - flow direction (Fig. D.8).
1 DIR : Flow measurement in 1 direction (+)
only (Fig. D.9).
