where:
T
Factor to convert selected time base to seconds
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 :
• If Frequency Factor is less than1 Hz, reconfigure the receiving device for a higher pulses/unit setting.
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:
• Rate Factor: 2000
• Frequency Factor: 333.33
8.4.3 Configure Frequency Output Direction

Frequency Output Direction controls how conditions of forward flow and reverse flow affect the flow rates
reported by the Frequency Output.
Actual flow direction interacts with Sensor Flow Direction Arrow to determine the flow direction that the
transmitter uses in processing. See the following table.
