Channels 1–4 measure Accumulated pulse from 0 to 1 million, after which the figure resets.
Channels 5–8 are virtual and offer 4 programming options:
1. pulses per second
2. pulses per minute (i.e., RPM)
3. pulses per hour
4. Accumulated pulse overflow. When selected, this option will count beyond the 1 million
limit of accumulated pulse on channels 1–4, adding a “1” to the total every time the corre-
sponding flow rate channel reaches 1 million.
The channels correspond as follows:
Channel #1: Pulse Count Total from input #1
Channel #2: Pulse Count Total from input #2
Channel #3: Pulse Count Total from input #3
Channel #4: Pulse Count Total from input #4
Channel #5: Rate or Count Overflow from pulse input #1
Channel #6: Rate or Count Overflow from pulse input #2
Channel #7: Rate or Count Overflow from pulse input #3
Channel #8: Rate or Count Overflow from pulse input #4
Calibration
Each channel of the Pulse Count Module can be individually calibrated with a multiplier. The
calibration multiplier can be used to properly scale the information coming from your trans-
ducer.
Example 1: Suppose you are monitoring liquid flow and each pulse from your transducer rep-
resents 50 gallons. If you enter a calibration multiplier of 50 for channel 1, then each pulse will
increment the total by 50. By calibrating the signal you can now keep a total that represents
total gallons instead of total number of pulses.
