• If connecting the 2551 Magmeter to a fl ow instrument from another
manufacturer, 5 to 24 VDC power must be provided to the 2551.
• A 10 KΩ pull-up resistor (not supplied) must also be connected
between terminals 1 and 2.
Calibration and Software Confi 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.

: 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
