GF Signet 2552 Metal Magmeter Flow Sensor - Manual (Page 8)

8 2552 Magmeter
• The 2552 outputs an open collector frequency signal that
can be connected to any powered Signet fl ow meter. (Models
5075, 5500, 5600, 8550, 8900.)
• DC power is provided to the 2552 Magmeter by all Signet
fl ow instruments. No additional power is required.
• If connecting the 2552 Magmeter to a fl ow instrument from
another manufacturer, 5 to 24 VDC power must be provided
to the 2552. A 10 K
Ω pull up resistor must also be connected
between the +V (Black) and the Freq. Out (Red) wires.
• ALWAYS connect AUX power on the 8550 to provide power
for the 2552 output signal.

• The 2552 receives 5 VDC power from the 8900.
No additional power is required.
6.3 Wiring the 2552-XX-12 Magmeter with 4 to 20 mA Loop Output
The 2552 Magmeter is a traditional 2-wire passive 4 to 20 mA loop transmitter.
•
External loop power (21.6 to 26.4 VDC, 22.1 mA maximum)
is required. (See Power Requirements on pg. 1)
The maximum loop resistance the Magmeter can
accomodate is 300 Ω.
The cable length from the Magmeter to the loop monitor
cannot exceed 300 m (1000 ft).
• All 2552 Magmeters are shipped from the factory with the 4
to 20 mA output scaled for 0 to 5 m/s (0 to 16.4 ft/s). If this
operating range is suitable, no adjustments are necessary.
The calibration charts in this manual list the 20 mA setpoint
for each pipe size. Use this information to program the 4 to
20 mA range of the loop device (PLC, Datalogger, recorder,
etc.).
