Product description
may be changed. With higher or lower pressure, corresponding measures must be taken (pressure
regulator, precision pressure regulator, available from Awite).
WARNING
The highest possible rated pressure is 100 mbar. In case of an error (e.g. precision pressure regulator
faulty), this must not be exceeded. This may result in leakage and consequent explosion. For higher
pressures, it is necessary to implement further safety measures as otherwise the safety of the gas
analysis system cannot be guaranteed.
4.4.6
Measuring gas, fresh air and exhaust air requirements
It has to be assured that no polluted flushing air or ambient air can be sucked in by the gas analysis
system and that the exhaust air hose remains free and unobstructed at all times.
CAUTION
Water, particles and dirt can clog pipes, sensors and valves. As a result, monitoring functions and thus
the measuring function can be impaired. Check the condensate traps daily.
When maintenance work is carried out on the gas pipe, the gas analysis system is to be switched off and
the ball valve at the measuring gas extraction point has to be closed.
WARNING
Work on the gas pipe may result in gas leakage. This creates a fire and explosion hazard. Switch off the
device during maintenance work and close the ball valve during gas sampling.
For AwiECO, the following applies: If there is a possibility of larger amounts of condensate in the
measuring gas pipe and if the condensate traps cannot be checked on a regular basis, an additional gas
cooler must be installed.
4.5
Hazards from gas
As the systems are used for the analysis of biogas and in a biogas system environment, the explosion
hazard has to be assessed prior to installation. A comprehensive risk assessment according to the
machinery directive is available from Awite. Technical data can be adapted to new technological advances
in the area of biogas by the manufacturer without any prior notice. Please contact Awite if you need
information about possible additions to this Instruction Manual and whether it is the current version.
