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.
