Configure Frequency Output Maximum Pulse Width - Emerson Micro Motion 1700 Configuration And Use Manual

Integrate the meter with the control system
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:
Set parameters as follows:

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.
The ON signal may be the high voltage or 0.0 V, depending on Frequency Output Polarity.
