TERM DEFINITION
Fractionation The process of separating a steam of natural gas liquids into its separate
components.
Freezing Point The temperature at which the substance goes from the liquid phase to the solid
phase.
Frequency The number of cycles per second for any periodic waveform - measured in
cycles per second - now called Hertz. The number of repeating corresponding
points on a wave that pass a given observation point per unit time.
Frequency Modulation Modulation where the frequency of the sinewave carrier alters with the
amplitude of the modulating signal.
Frequency Output An output in the form of frequency which varies as a function of the applied
input.
FRP Fiberglass Reinforced Polyurethane. A non-flexible material used for
LevelMaster sensors.
FS/2 Ruggadized handheld computer device for programming and collecting data
from an XFC. Also referred to a Husky or Dog Bone.
FT
3
A standard abbreviation for Cubic Foot.
Ftb Temperature Base factor.
Ftf Flowing Temperature factor.
Fuel Oils The heavy distillates from the oil refining process that are used primarily for
heating, for fueling industrial processes, for fueling locomotives and ships, and
for fueling power generation systems.
Full Bridge Wheatstone bridge configuration utilizing four active elements or strain gauges.
Full Duplex Simultaneous, two-way (transmit and receive), transmission.
Function A set of software instructions executed by a single line of code that may have
input and/or output parameters and returns a value when executed.
Fuse A short length of wire that will easily burn out when excessive current flows.
Fw Water Vapor factor.
G The symbol used for giga or gigabyte.
Gain The factor by which a signal is amplified, sometimes expressed in dB.
Gain Accuracy A measure of deviation of the gain of an amplifier from the ideal gain.
Gal An abbreviation for one gallon.
Gas That state of matter which has neither independent shape nor volume. It
expands to fill the entire container in which it is held. It is one of the three forms
of matter, the other two being solid and liquid.
Gas Chromatograph An analytical instrument that separates mixtures of gas into identifiable
components by means of chromatography.
Gas Chromatograph
Module Software module used in conjunction with PCCU32 and WINCCU to interact
with Btu Chromatograph equipment and software.
Gas Chromatograph
Module Coefficient A co-efficient generated by the factory allowing user to start calibration on
location without having a calibration gas available.
Gas Chromatography Preferred method for determining the Btu value of natural gas.
Gas Field A district or area from which natural gas is produced.
Gas Injection An enhanced recovery technique in which natural gas is injected under
pressure into a producing reservoir through an injection well to drive oil to the
well bore and the surface.
Gas Processing The separation of components by absorption, adsorption, refrigeration or
cryogenics from a stream of natural gas for the purpose of making salable liquid
products and for treating the residue gas to meet required specifications.
