To improve the system response, a by-pass can be added to increase
the sample flow rate to the analyzer by a factor of ten. A by-pass provides
a sample flow path around the analyzer of 2 - 18 SCFH. typically.
CALIBRATION GAS:
3000 series analyzer requirements for units with Auto-Cal options
are as follows:
The customer must supply control valves (or restrictors) for any SPAN
or ZERO gas source which is attached to the Auto-Cal ports. The valve
should be adjusted to the same flow rate as the sample gas. When restrictors
are used, the gas pressure must be adjusted to achieve the proper flow rate.
OPERATION WITHOUT A RESTRICTOR DEVICE:
Operation without a restrictor device is not recommend as
mentioned above. A 3000TA without any flow restrictor device was
tested on 11-19-97. This results in a flow rate of 2.4 SLPM @ 1 PSIG.
This is a cv of 0.023 for the standard sample system.
REFERENCE: FLOW_1.XLS & FLOW_2.XLS for information on
flow rates at various pressures.
