Transducer supplying more than 1 variable. Totalflow uses this term to
encompass units that read Static Pressure, Differential Pressure.
Historically these units were coined AMU for Analog Measurement Unit.
As a result of advanced technology, the unit no longer functions as only
an analog measurement unit. Therefore the newer terminology,
Multivariable Transducer, more aptly describes the functionality of this
design. The abbreviation IMV refers to the Integral version of the
multivariable. The abbreviation XIMV, refers to the XSeries IMV version
of the multivariable, which contains the circuitry as part of the unit and
the abbreviation IMVX, refers to the Explosion Proof IMV, where the
required circuitry resides on the Main Processor Board. See each
instance for additional explanation.
Acronym for Molecular Weight.
A standard abbreviation for Nitrogen.

process control technology in the chemical industry).
See Gas, Natural.
Material removed from natural gas at the "heavy end" portion; that is,
aliphatic compounds ranging from C4 to C8 (butanes and heavier).
The hydrocarbon components: propane, butanes, and pentanes (also
referred to as condensate), or a combination of them that are subject to
recovery from raw gas liquids by processing in field separators,
scrubbers, gas processing and reprocessing plants, or cycling plants.
The propane and butane components are often referred to as liquefied
petroleum gases or LPG.
A mixture of hydrocarbons, mostly pentanes and heavier, extracted
from natural gas, which meets vapor pressure and other specifications.
National Bureau of Standards.
See Normally Closed.
A standard abbreviation for Normal Butane.
A standard abbreviation for Normal Pentane.
National Electrical Codes
This refers to a response over a remote communication device, such as
a PING. Basically, saying, "I don't acknowledge your request!" This is
the opposite of ACK. NAK is a slang term that means that you disagree
or do not acknowledge something.
National Electrical Manufacturers Association.
A standard from the National Electrical Manufacturers Association.
Enclosure constructed for indoor/outdoor use to provide protection
against falling dirt, rain, sleet and snow and remain undamaged by
external formation of ice.
