Teledyne t100h 9.2.2.3. Sample Flow Calculation

Theory Of Operation Teledyne API - T100H Addendum to T100 Operation Manual)

9.2.2.3. Sample Flow Calculation

Unlike the T100, which uses a thermal-mass flow sensor to directly measure the gas flow though the instrument,

the T100H calculates the gas as follows.

 The ratio of the two pressures is measured and used to validate critical flow. If the ratio is not correct (<

2:1) the SAMPLE FLOW WARN message is activated. Also, the value of the SAMP FL test function is

set to XXXX.

If the pressure ratio between the two sensors is valid ( 2:1), the instrument calculates the flow based on sample

gas pressure level (PRES) and is viewable via the front panel as the SAMP FL test function.
