7.2.14 User-Defined Units
This function displays the instantaneous flow rate indicated in "A20 FLOW RATE" in
units other than those selectable with B04. If the specific gravity of the fluid is known,
the instantaneous flow rate can be displayed in weight units.
(1) User-Defined units for Instantaneous Flow Rate
Example: Displaying the flow rate of a fluid (its specific gravity is 2) in weight (kg)
in a flow rate span of 10m
3 /h. When the flow rate is 100%, 20,000kg is
displayed.
Display Description
Select "PROVIDED" in "D02."
For item "D03," set the value to be displayed in "A20 FLOW RATE" when the
flow rate is 100% in the span set in "B03FLOW SPAN." Set the unit in "D10".
Set the user-defind unit in "D10."
The maximum flow rate value of 20,000 kg is displayed as the instantaneous
flow rate in "A20 : FLOWRATE."
