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.
See Gas Chromatograph.
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.

The heating value measured in a calorimeter when the water produced
during the combustion process is condensed to a liquid state. The heat
of condensation of the water is included in the total measured heat.
