Overview of Smart Flow Meter Features
Dual Range or Dual Gas Calibration
If your meter is configured with a second factory calibrated flow
range, use an external contact switch to select the desired range.
Adjustable User Full Scale
Select from 50% to 100% of the factory full scale setting (factory
full scale is normally set to 125% of the user-specified maximum
flow rate). This adjustment is made for each flow range.
Alarm Settings
Program high and low or window alarm limits independently for
each flow range. (The solid state contacts are optically isolated.)
Adjust Alarm Deadband
You may enter an alarm deadband value that accommodates your
alarm settings.
Flow Totalizer
The flow totalizer counts only the currently selected range. When
ranges are switched the value of the non-selected range is stored in
memory.
Time Response Delay
Select from a low response for faster tracking to a high response
for a smoother output.
K-Factor
Use the K-factor feature to compensate for flow profile disturbances
or specific application conditions. The K-factor is a multiplication
factor applied to the linearized flow signal. You may set the K-factor
individually for each flow range.
Zero and Span Outputs
Validate and adjust the settings to ensure the 4-20 mA, 0-5 VDC or
optional 0-10 VDC output circuits are within specification.
Enable and Set Zero Flow Cut-off
This allows you to adjust the low-flow sensitivity which eliminates
false readings caused by leaky valves or convection effects in the pipe.
Read and Print the Factory Configuration
Useful for ISO 9000 compliance and other quality audits.
