How to use a pitot tube (optional)
The BIOGAS 5000 gas analyzer enables the site engineer to take gas measurements
using a pitot tube. The pitot tube is used for gas extraction systems and the pressure
readings are taken in mbar. Gas flow is calculated in the analyser in m
3
/hr (metres
cubed per hour).
Fitting a pitot tube to the analyzer:
1)
It is important to seat the pitot tube into the monitoring point with the tip facing
into the gas flow. The pitot tube should also be housed half way down the
monitoring pipe. (Please refer to the anemometer instructions, which detail how to
calculate the pipe diameter correctly).
2)
Make sure that the sample tubing attached to the pitot tube fits correctly.
3)
Attach the sample tube from the top connection of the pitot tube to the ‘blue port’
(the differential port) on the analyzer making sure that the gas port connector
secure into place.
4)
Attach the sample tube from the side of the pitot tube to the ‘white port’ (inlet
port/static pressure port) on the analyzer making sure that the gas port connector
secures into place.
5)
House the pitot gland correctly onto the monitoring point.
6)
Make sure the water trap filter is fitted as close as possible to the pitot tube. Make
sure that the water trap filter is clean and dry.
