Generally a location at which gas changes ownership, from one party to
another, neither of which is the ultimate consumer. It should be noted,
however, that the gas may change from one system to another at this
point without changing ownership. Also referred to as city gate station,
town border station, or delivery point.
The act of operating extensive low-pressure gas lines which aggregate
the production of several separate gas wells into one larger receipt
point into an interstate pipeline.
Agreement between a producer and a gathering system operator
specifying the terms and conditions for entry of the producer's gas into
the gathering system.
A pipeline, usually of small diameter, used in gathering gas from the
field to a central point.
A compressor station at which gas is gathered from wells by means of
suction because pressure is not sufficient to produce the desired rate of
flow into a transmission or distribution system.
The gathering pipelines plus any pumps, tanks, or additional equipment
used to move oil or gas from the wellhead to the main pipeline for
delivery to a processing facility or consumer.
A measure of the ratio of the relative change of resistance to the
relative change in length of a piezoresistive strain gage.
Absolute pressure minus local atmospheric pressure.
Instrument for measuring the relative pressure of a fluid. Types include
gauge, absolute, and differential.
This refers to a manual method of measuring the level of a liquid in a
tank. These measurements may be used to calibrate float levels.

The NGC8200's GC module is comprised of three parts: columns,
chromatographic valve and GC module circuit board. The valve controls
the flow of gas within the system. The columns perform the separation
of the gas into component parts for analysis. The GC module circuit
board contains the sensors for the carrier pressure regulators, the
sample pressure sensor and the thermal conductivity detectors (TCD's)
which detect the different gas components as they leave the GC
columns. It also contains an EEPROM or FLASH memory for storage of
calibration and characterization information of the module and its
sensors.
The GC Module is comprised of 3 parts; Columns, Valves and
Electronic Interface. The Valves control flow of gas within the system.
The Columns perform the separation of the gas into component parts
for analysis. The Electronic Interface contains pressure and
temperature sensors to monitor and detect the different gas
components as they leave the GC Columns.
