Configure Frequency Output Maximum Pulse Width - Emerson Micro Motion 2700 Configuration And Use Manual

Integrate the meter with the control system
The resulting Frequency Factor must be within the range of the frequency output (0 to
10,000 Hz):
•
•
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.
112
N Number of pulses per flow unit, as configured in the receiving device
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.
