• The next function block VCI, is a signal conditioning block. This block is used for
converting the analog input range (voltage or current) to engineering units. The default
configuration of this block is as shown in the next figure:
Figure 2 .28.
VCI Properties
• Type the name and description for this block as shown above. Move the cursor to the
Linearization Type field and click on the down arrow. Select Modifies Square Root as the
type from the drop-down menu. This will compensate for errors at very low flow
measurements.
• Change the Range to 0 to 200 and Quality limits also to 0 to 200. The measured signal (4-
20mA or 1-5V) will be interpreted as 0 to 200 flow units.
• We will not change anything else in this menu. Click on the OK button to complete the
configuration of this block.
Configure the AOUT block: Open the built-in analog output (AOUT) block.
• Configure the built-in output number (1 or 2).
• Configure the Action for this output (direct or reverse). Direct action specifies 4-20 mA
output for 0 – 100% output range. Reverse action specifies 4-20 mA for 100 – 0% output
range.
