User guide

6 2551 Magmeter
• When the blue jumper illustrated here is placed over both pins, the
2551-XX-11 outputs an open collector frequency signal that can be
connected to any powered Signet  ow meter (models 5600, 8900,
9900).
• 5 VDC power is provided to the 2551 Magmeter by all Signet  ow
instruments. No additional power is required.
• The frequency output will be displayed as positive  ow
regardless of the  ow direction.
• When the blue jumper illustrated here is removed (or placed over
one pin for storage) the 2551-XX-11 outputs a Digital (S
3
L) signal
compatible with the Signet 8900 and 9900.
• The 2551 receives 5 VDC power from the 8900 or 9900. No
additional power is required.
• The 8900 will display 0 (Zero)  ow rate during periods of
reverse  ow. The 9900 will display negative numbers to
indicate reverse  ow.
• The maximum cable length from the 2551 to the 8900 or 9900
depends on the 8900 or 9900 con guration. Refer to the 8900 or
9900 manual for complete information.

9. Calibration and Software Con guration
No calibration is necessary to begin using the 2551. The application and performance settings are pre-set to meet the requirements of
most applications.
The 2551 application and performance settings can be customized using the Signet 3-0250 USB to Digital (S
3
L) Con guration/
Diagnostic Tool and software. Refer to the Signet 3-0250 USB-to-S
3
L Con guration/Diagnostic Tool manual for details to adjust the
following parameters:
• 4 to 20 mA span: Factory setting is 0 to 5 m/s. Can be customized to any range.
• Noise Rejection Filter: Factory set for 60 Hz. Can be changed to 50 Hz.
• Low Flow Cutoff: Factory setting is 0.05 m/s. Can be customized to any velocity.
• Averaging Time: Factory setting is 14 seconds. Can be customized from 0.1 seconds to 100 seconds.
• Sensitivity: Factory setting is 25% of full scale. Can be customized to any % of full scale.
If connecting the 2551 Magmeter to a  ow instrument from
another manufacturer, 5 to 24 VDC power must be provided to
the 2551. A 10 K pull-up resistor (not supplied) must also be
connected between terminals 1 and 2.
