5.1 Volume measurement
EC350 generally operates in the Corrector mode. In this mode, EC350 receives and processes uncorrected
volume, pressure, and temperature inputs to produce corrected volume information.
The following image illustrates a typical Corrector mode display.
l
Top line of LCD display indicates the totalized corrected volume value.
l
Second line indicates the corrected volume unit of measure (e.g. MCF).
l
Third line indicates the item’s name (e.g. CORVOL, which is corrected volume).
l
Bottom line shows active icons to indicate various system status information.
5.1.1 Corrected volume
EC350 accurately measures and maintains the total uncorrected volume passing through the meter on
which it is installed. In addition to the uncorrected volume, EC350 also computes the corrected volume.
The corrected volume is computed by multiplying a total correction factor by the uncorrected volume input
from the meter.
EC350 maintains items called Hi-Res (High Resolution) volumes for indicating a fractional part of the
corrected and uncorrected volumes that are not visible in the primary items (0 and 2).
Total Correction Factor = Temperature Factor X Pressure Factor X Auxiliary Factor (normally 1.0) X
Squared Supercompressibility Factor.
EC350 supports a large range of units for measuring volume; some of them are as follows:
CF, CFx10, CFx100, CCF, CFx1000, MCF, CFx10000, m3x0.1, m3, m3x10, m3x100, and m3x1000.
You can independently configure corrected and uncorrected volume items.
