Basic configuration of flowmeter outputs includes:

•

Setting range values for the milliamp output.

•

Scaling the pulse output.

To configure the milliamp output: 

1. From the ProLink menu, click on Configuration.

2. Click on the Analog Output tab. The Analog Output panel appears, as shown in Figure 7-3.

3. Range values are flow rates represented by the milliamp output at 4 mA and at 20 mA. To set 

range values:

a.

Enter the flow rate that will be represented by the output at 4 mA into the Lower Range 
Value text box.

b.

Enter the flow rate that will be represented by the output at 20 mA into the Upper Range 
Value text box.

The Low Limit, High Limit, and Minimum Span display boxes in the panel indicate flowmeter 
limits, in the configured flow measurement unit.

-

The value entered into the Lower Range Value text box must be lower than the value 
entered into the Upper Range Value text box and higher than the displayed low limit.

-

The value entered into the Upper Range Value text box must be higher than the 
displayed low limit and lower than the displayed high limit.

-

The difference between the values entered into the text boxes should be greater than 
the displayed minimum span, or the milliamp output accuracy will be degraded.
