If “Unidirectional” is chosen, the output will give pulses proportional to flow rate when the
flow rate is positive, and will not give them when the flow rate is negative.
If “Bidirectional” is chosen, the output will give pulses proportional to flow rate in both flow
directions.
7.5.2.2 Units
First volume units for which we want to get a number of pulses are selected.
7.5.2.3 Pulses
Then the pulses per unit of volume that we will obtain at the output are selected .
7.5.2.4 Duty Cycle
With the duty cycle width or percentage of time the pulse will be active during each cycle
can be determined
Active pulse is when the NPN transistor at the output (see 2.2.5) is ON.
7.5.3 Analog output
The flow rate corresponding to 4 mA and 20 mA can be programmed and the calibration
for these two values can be made as well.
