Appendix B

Flow Totalizer

The Flow Totalizer consists of three numeric counters that keep track of the total flow being measured. Two software totalizers are standard with a third external mechanical totalizer as an option. The two software totalizers consist of a resettable totalizer and a non-resettable totalizer. Both totalizers are set to zero upon program start.

Scaling multipliers are provided to allow tailoring of the totalizer response to meet the requirements of the application. Some applications with high flow rates will require a high scaling factor, while low flow rates will require a low scaling factor.

The scaling factor is displayed whenever a total flow number is displayed. As indicated in the Status Screen below, the total flow is displayed as “TOTAL (x1000): 465 gal.” Multiplying the displayed total flow by the scaling factor (1000) gives an actual total flow of 465,000 gallons.

Modify Setup

Modify Setup selects a totalizer scaling factor and a flow unit of measure.

1.Highlight Modify Setup using the UP and DOWN. Press SELECT.

2.Set the Totalizer Scaling factor using the CHANGE CHOICE key. All three totalizers are scaled with one of seven scaling factors: X1, X10, X100, X1000, X10,000, X100,000 or X1,000,000. The selected scaling factor always applies to all totalizers. Press CHANGE CHOICE to cycle through the available scaling choices.

3.Press ACCEPT to continue.

4.Set the Total Flow Units using the CHANGE CHOICE key to cycle through the choices. Total Flow Units are independent of the flow units selected in the Setup Menu. Flow units of measure include:

•

Acre-feet

•

Liters

• Gallons

•

Cubic Feet

•

Cubic Meters
