An industrial data collection device similar to a PLC, designed for
location at a remote site, that communicates data to a host system by
using telemetry (such as radio, dial-up telephone, or leased lines).
The ability of a transducer to reproduce output readings when the same
measurement value is applied to it consecutively, under the same
conditions, and in the same direction. Repeatability is expressed as the
maximum difference between output readings.
The portion of natural gas remaining in a gaseous state after recovery
of certain components through gas processing.
The measure of the ability of a material to pass a current.
A relationship between a thermistors resistance and the temperature.
A metallic probe that measures temperature based upon its coefficient
of resistivity.
Passive component with a known resistance. The value of resistance is
usually shown by a set of colored bands on the body of the component.
The smallest significant number to which a measurement can be
determined. For example, a converter with 12-bit resolution can resolve
1 part in 4096.
A calculated value determined by analyzing a known substance under
precise conditions (temperature, pressure, carrier flow rate) which
equals the area of the peak divided by the weight or volume of the
injected substance. This calculated value is then used as a response
multiplier or offset for analyzing a "sample" of this same substance from
another source. In the case of Natural gas, each component will have
it's own Response Factor.
1) The length of time required for the output of a transducer to rise to a
specified percentage of its final value as a result of a step change of
input. 2) The time required by a sensor to reach 63.2% of a step
change in temperature under a specified set of conditions. Five time
constants are required for the sensor to stabilize at 600 of the step
change value.
This refers to a Totalflow procedure in which all the Station or
Configuration files are restored to the SDRIVE from the file located on
the laptop. This process is very helpful prior to doing a Cold Start when
you want to continue using the Configuration and Station files.
The ratio of inertial and viscous forces in a fluid defined by the formula
Re = rVD/µ, where: r = Density of fluid, µ = Viscosity in centipoise (CP),
V = Velocity, and D = Inside diameter of pipe.
See Radio Frequency Interference.
A flat cable in which the conductors are side by side rather than in a
bundle.
Natural gas which, based on its content of liquefiable hydrocarbons, is
suitable for processing in a gas plant for recovery of plant products.
