PULSE OUTPUT
Define the flow quantity per output pulse. This is expressed in units
per pulse (i.e. ft
3
/ pulse).
Note:
Ensure that the max. flowrate (full scale value) and the
pulse value entered here agree with one another. The max.
possible output frequency is 50Hz. The appropriate pulse
value can be determined as follows:
Pulse value >
estimated max. flowrate (full scale)/sec
required max. output frequency
Input:
Number with floating decimal point: 0.001...10000.0
Display:
1.000 ft3/P
PULSE VALUE
Set the pulse width required for external devices. The pulse width
limits the max. possible output frequency of the pulse output. For
a certain output frequency, the max permissible pulse width can be
calculated as follows:
Pulse width <
1 .
2 • max. output frequency (Hz)
Input:
Number with floating decimal point:
0.01...9.999 s (seconds)
Display:
.01 s
PULSE WIDTH
Frequency signals can be simulated in order to check any instrument
that is connected to the pulse output. The simulated signals are
always symmetrical (50/50 duty cycle).
Note:
• The simulation mode selected affects the frequency output.
The flow computer is fully operational during simulation.
• Simulation mode is ended immediately after exiting this
submenu.
Selection:
OFF, 0.0 Hz, 0.1 Hz, 1.0 Hz, 10 Hz, 50 Hz
