Pulsing Flow Support Function Setting; Power Frequency Synchronization Setting - YOKOGAWA Admag TI Series User Manual

5.5.3

Pulsing Flow Support Function Setting

If a pump, etc. is used, it may cause an error in the average of the flow rate due to the pulsing
flow. If the pulsing flow support function is used, an error due to a pulsing flow can be reduced by
following a flow rate change while controlling the flow rate calculation.
The setting can be configured with the following parameter.

Power Frequency Synchronization Setting

This function can be specified whether the excitation frequency (internal signal processing
frequency) and power frequency are synchronous or asynchronous.
When setting the excitation frequency and power frequency to asynchronous, the excitation
frequency is determined with the setpoint of the power frequency.
The power frequency synchronous/asynchronous mode and the power frequency can be
configured with the following parameters.
