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.)
RG
B
1 234567
8
00
9
GALLONS
,,,
In this case, the actual total is 1,234,567,800 gallons. However, the [0x00] ADAM-4000 holding
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 100).
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
[0x02] ADAM-4000 holding register will report the flow as 987,600 (milliGallons/minute). If
scaling to GPM is desired, then the polling device (master) must perform the floating point
conversion and scaling (divide by 1000).
Also, keep in mind that the EtherMeter reports all ADAM-4000 analog data in hexadecimal ASCII
format.
On the LCD display and within the ADAM flow registers, the following table displays the flow units
that pertain to the totalization units:
Totalization Units Flow Units
Gallons Gallons Per [Hour,Minute,Sec]
Cubic Feet Cubic Feet Per [Hour,Minute,Sec]
Liters Liters Per [Hour,Minute,Sec]
Cubic Meters Cubic Meters Per [Hour,Minute,Sec]
