G.2 Measurements
G.2.1 Flue gas, Flue gas + m/s, Flue gas + ∆p2
The
Flue gas + m/s
"Pressure/flow speed measurement" option.
The flue gas menus are the central measurement menus in which - in addition to the
readings measured with this function - the readings of all measurements carried out are
displayed (if this is selected in the
printed out from these menus.
The flue gas menus are always available, regardless of which sensors are connected.
Measuring functions of the three flue gas menus:
· The function enables flue gas to be measured.
Flue gas
· The
Flue gas + m/s
(+ air/mass flow calculation) by means of a Pitot tube (the connection cable for the
Pitot tube thermocouple should not be connected to the instrument probe socket).·
The Flue gas + ∆ ∆ p2
pressure measurement.
After measurements with high concentrations and longer measurements, the instru-
ment should be rinsed with fresh air in order to enable the measuring cells to regener-
ate, see Chapter Recommended rinsing times, p. 57.
For flow speed and differential pressure measurement:
Before beginning measurement, configure the location settings (shape and surface
area of cross-section, parameters), see chapter Location , p. 24.
Do not measure for longer than 5 min, as the drift of the pressure sensor means that
the readings could be outside the tolerance limits.
