American Society for Testing and Materials (ASTM International).
ASTM International Standard Practice for calculating heat value,
compressibility factor and relative density of gaseous fuels.
A communications protocol where information can be transmitted at an
arbitrary, unsynchronized point in time, without synchronization to a
reference time or "clock".
Automatic temperature compensation.
Term used for European Union's New Approach Directive 94/9/EC
which concerns equipment and protective systems intended for use in
potentially explosive atmospheres.
A unit of pressure; the pressure that will support a column of mercury
760 mm high at 0 °C.
The pressure exerted on the earth by the earth's atmosphere (air and
water vapor). A pressure of 760 mm of mercury, 29.92 inches of
mercury, or 14.696 pounds per square inch absolute is used as a
(scientific) standard for some measurements. Atmospheric pressure
may also refer to the absolute ambient pressure at any given location.
Generally in the range 20 Hz to 20 KHz.
To examine or verify data for accuracy. Totalflow's DB1 and DB2
records may be edited to generate a more accurate representation of
data information.
Using the Long Term Archive files to justify changes made to records
that more accurately reflects the correct data. Peripheral information
used to edit data is recorded without exception, to justify the accuracy
of the edited data records.
Similar to Automatic Fine Tune (AFT). A circuit that keeps a receiver in
tune with the wanted transmission.
American Wire Gage.
Acronym for American Wire Gauge.
Pressure against which a fluid is flowing. May be composed of friction
in pipes, restrictions in pipes, valves, pressure in vessels to which fluid
is flowing, hydrostatic head, or other resistance to fluid flow.
Technique used in chromatography to reverse direction of the flow after
the lighter components have been measured, allowing the heavier
components to remain in the column until measured, shortening the
length of the column.
Data is acquired by a DAQ system while another program or
processing routine is running without apparent interruption.
The total noise floor from all sources of interference in a measurement
system, independent of the presence of a data signal.
A system, device, file or facility that can be used as an alternative in
case of a malfunction or loss of data.
