For example: Maximum flow rate = 1200 kg/min

(1200 kg/min = 20 kg/sec)

If unit per pulse is set to 1200 kg per pulse, the Optical Pulse

Output will pulse once every minute.

If unit per pulse is set to 20 kg per pulse, the Optical Pulse

Output will pulse once every second.

The Optically isolated Pulse Output incorporate Pulse output queue, which accu-

mulate pulses if the Pulse Output is accumulating process flow faster than the

pulse output hardware can function. The queue will allow the pulses to “catch up”

later if the flow rate decreases. A better practice is to slow down the Pulse Output

by increasing the value in the Unit/Pulse setting in the Pulse Output menu (see

Figure 5.9).
