Ensure that operating pressure, temperature, and gas flow available are
within specifications.
Note
The sample take-out point may have an initial regulator to decrease
pressure in the sample line and increase the response of the system. If this is
the case, it should be set in the 5–10 bar G range, depending on the sample
line length to ensure 5 bar A at the input to the Sarasota SG901 system.

For the basic system, the operating pressure should be within the range of
the pressure transmitter (0.3–3.45 bar) and at least 0.4 bar above the
exhaust pressure. Ideally, the pressure should be close to 4 bar to minimize
pressure measurement errors.
For the dry and wet gas systems, the inlet pressure should be set according
to any factory acceptance test (FAT) documents, or close to 4 bar A to
minimize measurement errors. However, in some cases, the pressure may
deliberately set lower than this for operational reasons.
Note
Read any FAT records fully.

Set the flow rate so that the minimum flow rate meets the sample delay
requirements of the overall system. The higher the flow rate, the lower the
delay time. However, as the flow is increased, the waste exhaust gas volume
increases. A flow rate of 5 L/min is suggested as an initial value.
For details on commissioning the selected density converter, refer to the
user guide provided with it. Generally, the density converter should be set
to perform following tasks:

Calculate density with VOS correction (VibDim) calibration constants

Calculate density at reference conditions

Calculate SG / MW
