This refers to a response over a remote communication device to a
request such as a PING. Basically, saying, "I'm here, and I saw your
request!"
See Analyzer Control Module.
The degree of sound. The nature, cause, and phenomena of the
vibrations of elastic bodies; which vibrations create compressional
waves or wave fronts which are transmitted through various media,
such as air, water, wood, steel, etc.
Analog Output to a host providing power to the host.
An operational mode used by the LevelMaster for measuring dual float
levels by applying a signal to the primary windings, reading the voltage
level on the secondary windings and using an algorithm to determine
the oil and water levels.
A mechanism or device for attaching non-mating parts.
See Analog-to-Digital Converter.
A unique memory designation for location of data or the identity of a
peripheral device; allows each device on a single communications line
to respond to its own message.
The expansion of a gas, vapor, or liquid stream from a higher pressure
to a lower pressure in which there is no heat transfer between the gas,
vapor, or liquid and the surroundings.
The process of removing natural gas liquids from a stream of natural
gas by passing the natural gas through granular solids which have a
natural attraction to the liquids to be removed from the stream.
A length of wire designed to transmit or receive radio waves. (See also
Antenna)
Minute liquid particles suspended in gas. Aerosols will behave like a
fluid and can be transported by pipes and pumping. When aerosols
contact each other they coalesce into droplets. Aerosols may be
present in gas, or may be generated by glow shearing off the skim
inside of a pipeline.
American Gas Association. Trade group representing natural gas
distributors and pipelines.
American Gas Association Report No. 10, Speed of Sound in Natural
Gas and Other Related Hydrocarbon Gases. Method for calculation of
the speed of sound in gases.
American Gas Association Report No. 3, Orifice Metering of Natural
Gas. Method for calculating gas volume across an Orifice Plate. This
method requires two pressure readings, Differential Pressure (DP) and
Static Pressure (SP).
