The configuration drop-down houses six screens used to control how the flow meter is set up and responds to varying flow

conditions. The first screen that appears after clicking the Configuration button is the Basic screen. SeeFigure 40.

General

The general heading allows users to select the measurement system for meter setup, either English or metric and choose from

a number of pre-programmed small pipe configurations in the Standard Configurations drop-down. If pipe measurements

are to be entered in inches, select English. If pipe measurements are to be entered in millimeters, select Metric. If the general

entries are altered from those at instrument start-up, then press Download in the lower right-hand portion of the screen and

cycle power to the flow meter.

When using the Standard Configurations drop-down menu alternate, menu choices can be made by using the

following guidelines:

1. Select the transducer type and pipe size for the transducer to be used. The rmware will automatically enter the

appropriate values for that pipe size and type. Every entry parameter except for Units, MODBUS Address, Standard

Congurations, Frequency, Flow Direction and Specic Heat Capacity will be unavailable behind a grayed out entry box.

2. Go back to the Standard Congurations drop-down menu and select Custom. As soon as Custom is chosen, the previously

grayed out selections will become available for editing.

3. Make any changes to the basic conguration deemed necessary and press Download.

4. To ensure that the conguration changes take eect, turn the power o and then back on again to the transmitter.

Also under the General heading is a field for entering a MODBUS address. If the flow meter is to be used on a multi-drop RS485

network, it must be assigned a unique numerical address. This box allows that unique address to be chosen.
