The range of frequencies available for signaling; the difference between
the highest and lowest frequencies of a band expressed in Hertz.
Bar is equal to 1 atmosphere of pressure. I.e. .987 Standard
atmospheric pressure or 14.5 lbs./psia.
An instrument which measures atmospheric pressure.
A unit of liquid volume measurement in the petroleum industry that
equals 42 U.S. gallons (.159 cubic meters) for petroleum or natural gas
liquid products, measured at 60 degrees Fahrenheit and at an
equilibrium vapor pressure.
The pressure used as a standard in determining gas volume. Volumes
are measured at operating pressures and then corrected to base
pressure volume. Base pressure is normally defined in any gas
measurement contract. The standard value for natural gas in the United
States is 14.73 psia, established by the American National Standards
Institute as standard Z-132.1 in 1969.
Waste that collects in the bottom of vessels and tanks containing
petroleum or petroleum products.
Two or more electrochemical cells electrically interconnected in an
appropriate series/parallel arrangement to provide the required
operating voltage and current levels.
Unit of signaling speed. The speed in baud is the number of discrete
conditions or events per second. If each event represents only one bit
condition, baud rate equals bits per second (bps).
Serial communications data transmission rate expressed in bits per
second (b/s).
See Barrel.
Abbreviation for one billion standard cubic feet or one thousand MMcf
or one million Mcf.
A liquefied hydrocarbon product composed primarily of butanes and
natural gasoline.
Term used when calibrating. Amounts to offset the actual measurement
taken. On a LevelMaster, it refers to adjusting the measurement of the
float level to agree with a calibrated measurement. On an RTD
(Resistant Thermal Detector), it refers to adjusting the measurement of
the temperature to agree with a calibrated temperature. This figure
maybe either a positive or negative figure.
A very low-level DC current generated by the panel meter and
superimposed on the signal. This current may introduce a measurable
offset across a very high source impedance.
System based on the number 2. The binary digits are 0 and 1.
A code for representing decimal digits in a binary format.
