Using the Smart Interface Software Basic Features
The Sierra Smart Mass Flow Meter does not require any adjustment
to be operational. If changes are needed, it’s a good idea to make a
backup file of the current configuration before entering any new pa-
rameters (see page 18). It is important to note that any changes
made to the flow meter settings take immediate effect. Make sure
that the flow meter is not actively monitoring or reporting flow to
any master control system during programming. This software is
intended as a set up program only and should not be used to con-
tinuously monitor flow.
When you are ready to begin, you may use Smart Interface software
main screen to:
• read system variables
• re-range the meter
• enter a new correction factor
• change the zero flow cut off value
• enter high and low alarm trip points
• change the alarm deadband value
• select a new speed of response
You may select the Advanced Options button (page 16) to save
Smart settings to disk, upload data to the currently connected flow
meter or adjust the zero and span analog outputs.
You may select the Validation button (page 19) to reset the totalizer,
view calibration data or perform the flow meter validation procedures.
Smart mass flow meters have a second flow range, Range 2.
(Calibration is optional for Range 2.) The Range Indicator on the
lower left of the screen indicates the currently selected range. Make
certain to check which range is active before making any changes to
the user full scale, alarms, K-factor or totalizer reset. To select
Range 2, jumper RNG2 with GND on the meter terminal block.
Remove the jumper to return to Range 1. It is not necessary to re-
start the software when changing ranges. To install a permanent
range selection contact switch, see the wiring instructions given in
the flow meter manual.
