EXAMPLE:

Consider the following case of a meter register installed on meter channel 1. This register

contains 8 variable digits plus two (2) fixed zeros on the right. (EXP1=+2.)

1 234567

GALLONS

,,,

In this case, the actual total is 1,234,567,800 gallons. However, the [N7:0,1] register will report

the total as: 12,345,678. If scaling to GALLONS is desired, then the polling device (master) must

perform the scaling (multiply by 10

(EXPn)

or 10

[N7:21]

or 100).

If EXPC is set to +3 (factory default), then the [N7:38,39] upper totalization register will contain

1,234,567 (KGals) and the [N7:42] lower totalization register will contain 800 (Gals).

Regarding flow, all reported flow rates are multiplied by 1000 to eliminate the need for floating

point formatting within the EtherMeter. In this case, if the actual flow rate is 987.6 GPM, then the

[N7:4,5] register will report the flow as 987,600 (milliGallons/minute). If scaling to GPM is

desired, then the polling device (master) must perform the scaling (divide by 1000).
