N Number of pulses per flow unit, as configured in the receiving device
The resulting
Frequency Factor
must be within the range of the frequency output (0 to
10,000 Hz):
• If
Frequency Factor
is less than1 Hz,reconfigure the receiving device for a higher
pulses/unit setting.
• If
Frequency Factor
is greater than 10,000 Hz, reconfigure the receiving device for a
lower pulses/unit setting.
Tip
If Frequency Output Scale Method is set to Frequency=Flow , and Frequency Output Maximum Pulse Width is set
to a non-zero value, Micro Motion recommends setting
Frequency Factor
to a value below 200 Hz.
Example: Configure
Frequency=Flow
You want the frequency output to report all flow rates up to 2000 kg/min.
The frequency receiving device is configured for 10 pulses/kg.
Solution:
FrequencyFactor = x 10

Overview
Frequency Output Maximum Pulse Width is used to ensure that the duration of the ON signal is
great enough for your frequency receiving device to detect.
