Gas sampling and gas conditioning technology 4-1.1-ME

NOTE!

Adjust the flow meter FM1 to a flow rate above the demanded alarm value.

Because of breaking the outlet dew point (5°C) the total flow rate should not

pass the specified maximum value (see 2.).

The minimum flow rate is determined by the sample gas pump. This re-

quires the following minimum values:

N3 KPE: approx. 60l/h;

N9 KPE: approx. 200l/h;

If the flow rate remains under the minimum value the pump membrane can

be premature destroyed by over pressure !

17.2 CHECK/CALIBRATION

 turn switch to ‘Check’ (LED yellow); is available as contact outlet;

 turn switch to ‘Test gas’ (LED yellow);

 turn switch to ‘Zero gas’ (LED yellow);

After this calibration or checking the measuring range with zero gas can happen.

 turn switch to ‘Span gas’ (LED yellow);

Now calibration or checking the measuring range with span gas can be started.

For returning to the measuring mode:

 turn switch to ‘Sample gas’ (LED yellow);

If the analyser has reached the measuring range:

 turn switch to ‘Measure’ (LED yellow).
