Pulse Output and Pulse Output Width
Pulse Output is used to activate a sampler or external totalizer. The number selected will be pulses per unit
volume or per unit mass. If 0.1 pulse is selected, the one pulse will be given every 10-unit volumes has
passed through the meter.
Pulse Output Width is the duration, in milliseconds, of one complete pulse cycle (where each cycle is the
pulse plus a wait period, in a 50/50 ratio). For example: if POW = 500 millisecond, the Flow Computer at
most can produce one pulse each second regardless of the pulse per unit volume selected (500 millisecond
pulse + 500 millisecond wait). If POW = 10 millisecond the Flow Computer can produce up to 50 pulses
per second.
The Flow Computer’s maximum pulse output is 125 pulses/second. The Pulse Output in combination with
the Pulse Output Width should be set so that this number is not exceeded.

4-20mA selection must be proportional and within the range of the selected parameter. The 4-20mA signal
is 12 bits.
