THE GAS PARAMETERS MENU

This menu becomes available after picking a Meter Type and Measurement Channel. We recommend
that you edit the Gas Parameters immediately after creating a new Site Setup, however any item in the
Gas Parameters menu can be altered at any time, even during normal meter operation. The default
setting are probably suitable for most applications, however if reliable data can be provided regarding
the gas specific heat ratio, gas viscosity or gas compressibility factor, these settings should be modified.
The flowmeter uses the Gas Parameters data to establish the specific gravity and the volume correction
factors required for mass flow or standard volume computations. The Gas Parameters menu allows you
to edit the base temperature and base pressure settings that the computer uses when it applies the
standard volume correction to the measured volumetric output. The specific heat ratio item is required
for the computation of the average gas specific gravity. The Viscosity (cP) item is needed for proper flow
profile compensation. The fixed MW (molecular weight) item allows you to force the flowmeter to use a
specific molecular weight for well-defined gases. The fixed Temperature and Pressure items allow you to
set these parameters when external pressure and temperature (analog inputs) are not available. The
meter is also capable of providing an AGA8 volume compensation for fixed gas compositions. This is
accomplished by creating an offline lookup table that contains the compressibility and density values for
a defined range of pressure and temperature. Once completed, the table must be downloaded to the
FUG1010GCN (refer to paragraph 4.3.9).
The menu screen and list below shows the defaults and descriptions for all the Gas Parameters menu
items. Each item in the gas parameters menu can be edited by the user. Pressing the <Right Arrow> key
on any of these menu items will enable numeric entry, allowing you to override the default values.
