Measurement concept of GasLab Q2

3.3 System setup

A typical setup consists of a sample line from the gas pipeline to the analyzer. The measurement
is made rapidly and continuously. A gas stream is fed to the measuring device from the pipeline,
measured and fed into the exhaust tube. If the pipeline pressure is higher than the maximum inlet
pressure of the Q2, a pressure reduction must be set before the gas inlet for process gas.
The operational calibration gas is normally located close to the Q2. It is supplied by a 10 l cylinder
with a pressure reducer and provides the measuring accuracy. This gas supplies last for several
years of service, and the calibration gas is also available in other sizes of cylinders upon request.
The exhaust tubing should be laid separately, details see chapter 5.3.5. In general, all tubing and
components should be assembled as fixed gear. The power supply and the communication cables
should be connected and installed as usual in an industrial environment. The following diagram
