Description and settings
3.4.0 FREQ.
OUTP.F
Submenu 3.4.0 Frequency output
F
3.4.1 FUNCTION F Function, frequency output F
• OFF (switched off)
• F/R IND.
(F/R indication, e.g. for I)
• 1 DIR. (1 flow direction)
• 2 DIR. (forward / reverse flow,
F/R measurement)
• SP. SOUND (sound velocity)
3.4.2 PULSOUTP Unit of frequency output F
• PULSRATE
(setting in pulses per unit time)
• PULSE/UNIT (setting in pulses
per unit volume)
3.4.3 PULSRATE Pulse rate for 100% flowrate or for
sound velocity, see Fct. 3.1.1 or
3.1.8 + 3.1.9 (appears only if
PULSRATE set under Fct. 3.4.2)
Value:
2.778*10 -3 - 1000 PuLSe/Sec (= Hz)
or 0.1667 - 60,000 PuLSe/min
or 10 - 3,600,000 PuLSe/hr
After selecting unit, call numerical
value with ↵ key, 1 digit flashes.
3.4.3 PULSE/UNIT Pulse value for flowrate unit
(appears only if PULSE/UNIT set
under Fct. 3.4.2)
Unit: PuLSe per m 3 , Liter, US Gal or
unit of Fct. 3.6.6, 3.6.7+3.6.8
Value:
0.0001 to 9.9999*10 9 PuLSe
(no check, but Q
100% *pulse value
≤ 3.600.000 pulses/hr).
After selecting unit, call numerical
value with ↵ key, 1 digit flashes.
3.4.4 PULSWIDTH Pulse width for frequenc ≤ 10 Hz
• 30 mSec • 200 mSec
• 50 mSec • 500 mSec
• 100 mSec
3.4.5 TIMECONST.
F
Time constant
of frequency output F
• 40 mSec
• SAME AS I
(time constant for F same as for I,
see Fct. 3.3.6)
3.4.6 L.F.CUTOFF
F
Low-flow cutoff (SMU) for frequency
output required?
Setting: NO or YES
3.4.7 CUTOFF ON Cutoff “on” value SMU-F
(appears only if YES set
under Fct. 3.4.6)
Value: 01 - 19 PERCENT of Q
100%
(Fct. 3.1.1)
3.4.8 CUTOFF
OFF
Cuttoff “off” value SMU-F
(appears only if YES set
under Fct. 3.4.6)
Value: 02 - 20 PERCENT of Q
100%
(Fct. 3.1.1),, value must be greater
than of Fct. 3.3.8
