TAKING A PRESSURE READING
NEVER ATTEMPT TO TAKE A PRESSURE READING WITHOUT
KNOWING THE MAXIMUM PRESSURE THAT MIGHT BE
PRESENT, THIS INSTUREMENT’S PRESSURE TRANSDUCER
IS RATED AT 2 PSI.
A flue draught measurement can be made at any time.
Connect the standard probe to pressure sensor inlet and the probe in the
flue, the pressure reading will be displayed. To perform a combustion
test and display draught at the same time a special probe is required,
contact Kane International or an Authorised Distributor for details.
TAKING A FLOW READING
In the UNITS menu set the pressure units to metres/sec (m/sec), these
are the only units available for the flow measurements.
This also sets the pressure display to Pascal (Pa), there is a range limit
for the Pitot calculation of 15Pa to 4600Pa (0.15mbar to 46mbar).
For the most accurate flow measurement the flue gas temperature
should also be measured, if a flue temperature probe is not fitted then
the internal ambient measurement is used. Flue temperature must be
between -10°C to +650°C.
REGULAR CHECKS DURING SAMPLING
Care must be taken at all times not to exceed the analyser’s operating
specifications, in particular ensure the following:-
•
Do not exceed the maximum temperature of the flue probe.
•
The analyser internal temperature does not exceed normal
operating range, typically 0-50°C.
•
DO NOT PLACE THE ANALYSER ON A HOT SURFACE.
•
The water trap is vertical at all times, water condenses in the probe
line and can quickly fill the water trap when the probe is moved.
Take care and watch the water trap closely.
•
The in-line particle filter is clean and does not become blocked.
