6.2.3.1. Flue Gas, Flue Gas + m/s, Flue Gas + Δp, Program for all
analyzer boxes, Exhaust Gas before + after catalyst
The flue gas menus (Measurement Type) are the central
measuring menus, which – in addition to the readings measured
with this function – contain the readings of all measurements
performed (if selected in the menu Measurement view). All
readings can also be saved in or printed out from these menus.
The flue gas menus can always be selected, irrespective of the
plugged in sensors.
Measuring functions of the flue gas menu:
• The measurement type Flue Gas can be used to perform a flue
gas measurement.
• The measurement type Program for all analyzer boxes can
be used for i.e. a bus system, in which several flue gas
analyzers are interconnected. A measuring program can
thereby be defined and transferred to all analyzer boxes.
• The measurement type Exhaust Gas before + after cat
enables synchronous measuring of exhaust gas concentration
before and after the catalyst. For this flue gas menu two
measuring boxes are required, which are linked via the testo
data bus. The readings of both analyzer boxes are displayed
parallel in the display of the control unit to provide a quick
overview over the condition of the catalyst.
• With measurement type Flue Gas + m/s a flue gas
measurement can be performed in parallel to a flow
measurement (+ volume / mass flow calculation) via a Pitot tube
(the connecting cable for the thermocouple of the straight Pitot
tube must thereby not be connected to the sensor socket of the
instrument).
• The measurement type Flue Gas + ∆P can be used to perform
a flue gas measurement with parallel differential pressure
measurement.
After measurements with high concentrations and after
longer measurements the instrument should be rinsed with
fresh air, so that the sensors can be regenerated again.
