Flow error
Condensation in the flowmeter
• Disconnect gas analyzer from the gas conditioning system.
• Dry the flow meter by heating it and blowing it with compressed air.
• Check the operation of the upstream sample gas cooler.
Inadequate gas supply
• Connect the flow meter, ball chamber or pressure gauge directly to the
gas supply pump and measure the pressure or vacuum.
• Check the pump and change the membrane if necessary.
• Check the disposable filter and replace (see page 314) if necessary.
• Check the solenoid valve(s) and replace if necessary.
