PARAMETERS
• KA ADJUSTMENT
It allows the adjustment of the calibration factor KA.
Caution! Changes to the KA factor can only be made by authorized
persons. The KA factor must be the same as the coupled sensor; check
it on the flow meter plate.
• DIAMETER ADJUSTMENT
It allows the diameter adjustment. In case of insertion flow meter, please
enter the real inner diameter value of the pipe in this menu.
• FILTER SETUP
Filters should be adjusted only if strictly necessary. Factory settings
are already calibrated for proper operating conditions.
» Flow cut off
In this sub-menu you will find a value expressed as a percentage of full scale:
if the actual flow rate is less than this value, the device will show a flow equal
to 0.
Should you need to reduce the flow cut-off filter, it means that the
speed of the liquid is lower than the recommended one necessary for
precise measuring.
» Damping
Indicates the number of mediated samples which are used to obtain instantaneous
flow rate shown on the display and transferred to the 4-20 mA outputs and
frequency. To increase the stability, increase the value in this sub menu.
» Bypass
A value expressed in percentage is inserted in this sub-menu. It represents a
threshold beyond which the damping filter IS NOT applicated.
For example:
If the value of 50% has been selected:
IF the flow rate varies by 50% more than previous value
THEN the indicated flow rate will have the real value.
OTHERWISE the damping filter will be applicated, in other words, the indicated
flow rate will reach slowly the real value.
» Peak cut-off
In this sub-menu you will find a value expressed as a percentage of full scale.
If the measurement of the flow rate shows amplitude peaks > of the set value,
these will not be taken into account in the measurem
ent.
For example:
Setting the value to 10%, a peak > 10% of full scale will be ignored by the
device.
» Average measure
Indicates the number of mediated samples which are used to manage the
increase of the totalizers and pulse outputs.
To increase the stability, increase the value in this sub-menu.
