Section 3 Operation
Operating Procedure
After the flowmeter has been properly installed in the process, it is ready for
operation. In most cases, particularly in high flow (> 100 slpm) and/or high
pressure (> 150 psig) applications it is recommended to slowly initiate flow in
order to reduce servere pressure surges. Where possible, use a bypass pip-
ing arrangement to bring flow smoothly on-line. When starting pumps to sup
-
ply the flowmeter, use an isolation valve between the pump and the flowmeter
in order to prevent pressure surges.
Features
Note: Not all features are available on all instruments.
SLAMf Series Standard
The Brooks SLAMf is a full-featured digital MFC. The Brooks SLAMf performs
much like a traditional analog MFC, but with improved accuracy, step re-
sponse and valve control. The analog interface matches that of Brooks' popu-
lar analog MFCs so it can be retrofitted into tools using analog MFCs. Other
versions of the SLAMf Series can provide a variety of digital protocols.
The Brooks SLAMf
is capable of storing up to 6 different sets of gas calibra-
tion data. Each set includes a calibration curve, PID controller settings, valve
performance data, and information about the calibration conditions. The
Brooks SLAMf can contain calibrations for different gases or for the same gas
at multiple conditions (pressures, full-scale flow rates).
Calibrations will appear in the calibration table in the same order as they ap-
peared on the customer order, unless otherwise specified. The first listed gas
will appear as calibration #1 the second as calibration #2 and so on. Note that
unless specified otherwise on the customer order any unit containing a single
calibration will have that calibration stored in calibration position 1.
