Requirements
Insert the flue gas probe in the flue and connect to the instrument.
The measurement of the flue gas temperature is made by the thermocouple
at the tip of the flue gas probe. The probe pipe protects the thermocouple,
but has openings to allow the stream of flue gas to envelope the
thermocouple.
Positioning the flue gas probe in the flue gas stream
The thermocouple must always be exposed to the stream of flue gas to allow
an exact measurement of the flue gas temperature and thereby a precise
determination of the flue gas losses. It must not be screened by a web of the
probe pipe.
Thermocouple tip
The tip of the thermocouple must not touch the guard! If necessary, bend the
tip of the thermocouple accordingly.
