BY-PASS:
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. The
customer must supply a control valves (or restrictors) for any SPAN or ZERO
gas source which is attached to the Auto-Cal ports. The valve should be ad-
justed 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 3010TB 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 sys.
REFERENCE: FLOW_1.XLS & FLOW_2.XLS for information on
flow rates at various pressures.
