2551 and 2552 Magmeters

The setup capability of the 0250 is more complex with the magmeters than with other sensors. Read these instructions carefully before
attempting to modify a Magmeter.

Connect the Magmeter to the computer:

• Connect the Magmeter to the 3-0250 as illustrated.

• For 3-2551-11 models: The frequency/digital jumper MUST be in the Digital position.

• Connect the isolated 24 VDC power source to 4-20 mA model Magmeters.

• Connect the Signal Converter to any open USB port on the computer.

2551 and 2552 Magmeter Setup

1. Set the general information about the pipe and application preferences in the Application Settings fi elds.

Flow/Velocity Units (factory set: Meters)

• Select the engineering units from the list: meters, feet, cubic meters, liters, cu. ft., U.S. gallons, Imp. gallons.

Timebase (factory set: Seconds)

• Set the timebase preference: seconds, minutes, hours, days

Pipe ID (Inside Diameter) (factory set: 44.0)

• Enter the inside diameter of the pipe.

ID Units: (factory set: millimeters)

• Select inches or mm for the dimensions of the pipe.

K-Factor (factory set: 65.7667)

• K-factors are published as "pulses per gallon" and "pulses per liter" in the Magmeter manual.

• Click the "?" to open a copy of the manual (manual fi le must be placed in the same directory as the 3-0250.exe application fi le).

K-factor units (factory set: pulses/liter)

• Select pulses/gallon or pulses/liter.

2. Set the 4-20 mA span (If applicable)

4 mA Setpoint (factory set: 0 m/s)

• Enter the fl ow rate where the Loop output must equal 4 mA.

20 mA Setpoint (factory set: 5 m/s)

• Enter the fl ow rate where the Loop output must equal 20 mA.

3. Set the Performance Settings to best accomodate the unique conditions in the pipe.

Averaging Time (Factory set:14 s)

• Set the time the Magmeter will use as the averaging period. Example: 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 fl ow in the pipe
is erratic.

Quick Response Sensitivity (Factory set: 25)

• Set the percentage of change in the fl ow rate required to allow the Magmeter to override the AVERAGING and jump

to a new fl ow rate immediately. (2551 maximum range is 10 m/s)
A detailed explanation of Averaging and Sensitivity functions is provided on Page 5.

Noise Rejection Frequency (Factory set: 60 Hz)

• Select 50 Hz or 60 Hz according to local AC power specifi cations.

Low Flow Cut-off (Factory set: 0.05 m/s)

• Set the fl ow rate where all Magmeter outputs will be forced to zero.

(When the fl ow rate drops below this value, the frequency output will be 0 Hz. and the current output will be 4 mA.)

4. Click "Write" to copy the new settings into the Magmeter.

• To repeat the same settings in another Magmeter, disconnect the Magmeter and connect the second Magmeter.
Note: For 4-20 mA models, remove 24 VDC power before rewiring.)

• Click "Write" again.
Note: All settings are lost when you exit the program. If the settings will be used again, click "SAVE". Name the fi le and save it on

the computer hard drive.

Magmeter Averaging and Sensitivity Settings

Because ideal fl ow conditions are often impossible to acheive, the fl ow rate is often erratic, which in turn causes any control features
(ie; relays, 4-20 mA loops, etc.) that are associated with the fl ow rate to also be erratic.

The best solution to these problems is to correct any piping defi ciency 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 defi ciencies. They are called "Performance Settings"
and can be modifi ed 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 fl ow 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 fl ow rate required to allow the Magmeter to override the AVERAGING and jump to a new fl ow
rate immediately. (maximum range is 10 m/s)

The pictures below illustrate the effect of these settings.

No AVERAGING, no SENSITIVITY

With AVERAGING set to 0 (zero) the SENSITIVITY is ineffective,
and the fl ow rate may be very unstable. This will cause the output
signals to respond erratically.

AVERAGING Only

With AVERAGING set to 60 seconds and SENSITIVITY set to
100%, the fl ow rate is stabilized, but a sharp change in fl ow 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 fl ow rate is stabilized, but the sudden shift in fl ow is refl ected
very quickly.

Datalogger Operation

The 0250 can serve as a fi eld data logger that downloads data directly into a *.csv (Comma Separated Value) fi le.
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 fi les in *.csv format. The maximum number of records allowed for this type of fi le is 65535.
If the logging interval is 60 seconds, the largest fi le 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 fi le 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-fi le session the Begin Monitor and Save Log functions are disabled,
while the Pause and End Log functions are enabled.
