AVERAGING Only
With AVERAGING set to 60 seconds and SENSITIVITY set to
100%, the flow rate is stabilized, but a sharp change in flow rate
is not represented for 60 seconds or longer. This can cause
system problems if one of the operating setpoints falls within this
range.
AVERAGING and SENSITIVITY
With AVERAGING at 60 seconds and SENSITIVITY set to 25%,
the flow rate is stabilized, but the sudden shift in flow is reflected
very quickly.
No AVERAGING, no SENSITIVITY
With AVERAGING set to 0 (zero) the SENSITIVITY is ineffective,
and the flow rate may be very unstable. This will cause the output
signals to respond erratically.

Magmeter Averaging and Sensitivity Settings
Because ideal flow conditions are often impossible to acheive, the flow rate is often erratic, which in turn causes any control features
(ie; relays, 4-20 mA loops, etc.) that are associated with the flow rate to also be erratic.
The best solution to these problems is to correct any piping deficiency that causes the instability. This may involve longer straight runs
upstream, reducing the pipe size to maintain a full pipe at all times, and other installation changes. In many situations, however, these
measures are simply not possible.
The Magmeter provides several tools that are designed to "work around" these deficiencies. They are called "Performance Settings"
and can be modified only through the 3-0250 Setup Tool. The noise rejection and the Low Flow Cutoff settings are self-explanatory. The
Averaging and the Sensitivity features should be studied before making adjustments.
Averaging Time in Seconds (Factory set: 14 seconds)
• Set the time the Magmeter will use as the averaging period.
With averaging at 14 seconds, each display is an average of the previous 14 seconds input.
Use higher averaging times to smooth the display and current output where the flow in the pipe is erratic.
Quick Response Sensitivity (Factory set: 25% of Maximum Range, or 2.5 m/s)
• Set the percentage of change in the flow rate required to allow the Magmeter to override the AVERAGING and jump to a new flow
rate immediately. (maximum range is 10 m/s)
The pictures below illustrate the effect of these settings.

Datalogger Operation
The 0250 can serve as a field data logger that downloads data directly into a *.csv (Comma Separated Value) file.
Note: The 0250 does NOT have internal memory to store data. It must be connected to a computer to use the datalog function.
• Select the sensor type, click on "Read".
• Click Monitor/Verify Sensor to open a datalog setup window.
• Enter the Logging Interval. This value represents the time between log records.
The minimum interval is 1 second, and the maximum interval is 86400 seconds (24 hours). Example: If the Log Interval is set to
60 seconds, the 0250 will record the temperature once every minute.
• The 0250 saves data files in *.csv format. The maximum number of records allowed for this type of file is 65535.
If the logging interval is 60 seconds, the largest file possible is 65535 records, or 1092 hours of continuous recorded data.
• To initiate a log session click Begin Monitor or Begin Log to File.
Begin Monitor
• This function starts monitoring the sensor output and displays values on a graph, but does not store the data permanently. During
the monitoring session the Begin Log to File and Save Log functions are disabled, while the Pause and End Log functions are
enabled. Save Log enables a monitoring session to be saved immediately after End log is clicked.
Begin Log to File
• This function prompts the user to create a file on a computer drive before it starts monitoring. The system then begins recording the
sensor output and display values on a graph. During a Log-to-file session the Begin Monitor and Save Log functions are disabled,
while the Pause and End Log functions are enabled.
