TERM DEFINITION
CNG See Compressed Natural Gas
CO
2
A standard abbreviation for Carbon Dioxide.
Coalbed Methane A methane-rich, sulfur-free natural gas contained within underground coal
beds.
Coefficient of expansion The ratio of the change in length or volume of a body to the original length or
volume for a unit change in temperature.
Coil A conductor wound in a series of turns.
Cold Start A rebooting technique which will clear all operational errors, loose all data files,
but will not damage configuration files if stored on the SDRIVE.
Cold Weather Enclosure
Totalflow insulated and heated enclosure designed to house either the
NGC8200 or Btu 8000/8100 Chromatographs in inclement climates.
Collector The semiconductor region in a bipolar junction transistor through which a flow
of charge carriers leaves the base region.
Column Hardware component used in gas chromatography to separate components
into measurable units.
Combustible Classification of liquid substances that will burn on the basis of flash points. A
combustible liquid means any liquid having a flash point at or above 37.8°C
(100°F) but below 93.3°C (200°F), except any mixture having components with
flash points of 93.3°C (200°F) or higher, the total of which makes up 99 percent
or more of the total volume of the mixture.
Comma Separated Values These file types are importable records used by spreadsheet programs to
display and manipulate data.
Communication Transmission and reception of data among data processing equipment and
related peripherals.
Communication Port Comm. Port (abbreviation) refers to the host computer's physical
communication's port being used to communicate with the equipment. Used by
Totalflow when discussing local or remote communication with various
equipment including the XFC, FCU, XRC, RTU and LevelMaster etc.
Compensation An addition of specific materials or devices to counteract a known error.
Complimentary Metal-
Oxide-Semiconductor Family of logic devices that uses p-type and n-type channel devices on the
same integrated circuit. It has the advantage of offering medium speed and
very low power requirements.
Component (1) A small object or program that performs a specific function and is designed
in such a way to easily operate with other components and applications.
Increasingly, the term is being used interchangeably with applet. (2) A part of a
device.
Compressed Gas A gas or mixture of gases having, in a container an absolute pressure
exceeding 40 psi at 21.1°C (70°F). A gas or mixture having in a container, an
absolute pressure exceeding 104 psi at 54.4°C (130°F) regardless of the
pressure at (21.1°C (70°F). A liquid having a vapor pressure exceeding 40 psi
at 37.8°C (70°F) as determined by ASTM D-323-72.
Compressed Natural Gas Natural gas in high-pressure surface containers that is highly compressed
(though not to the point of liquefaction). CNG is used extensively as a
transportation fuel for automobiles, trucks and buses in some parts of the world.
Small amounts of natural gas are also transported overland in high-pressure
containers.
Compressibility The property of a material which permits it to decrease in volume when
subjected to an increase in pressure. In gas-measurement usage, the
compressibility factor "Z" is the deviation from the ideal Boyle and Charles' law
behavior. See SUPERCOMPRESSIBILITY FACTOR.
