1.
Do not remove from pressurized lines! Do not remove safety ring from sensor. Unit may become a
dangerous projectile if safety devices are disabled.
2.
Do not open wiring access plate in humid environment. Moisture in terminal area may cause
instrument failure.
3.
In EDIT mode, all the output functions of the +GF+ SIGNET 2550 Insertion Magmeter are still
active, so the control process is uninterrupted.
4.
The +GF+ SIGNET 2550 Insertion Magmeter weighs 11 lbs. Care must be taken to properly
support the unit with straps and/or bracing when necessary.

Description
The latest in bipolar pulsed DC technology and the best features of an insertion sensor are packed into the +GF+ SIGNET 2550
Insertion Magmeter. Simple installation, easy maintenance, and state-of-the-art microprocessor technology make the 2550 the best
alternative to traditional full-line magmeters. The 2550 is based on the Faraday principle, and provides current frequency output signals
proportional to the flow rate. The system incorporates automatic temperature compensation, resulting in outputs that are accurate
within
±
2% of actual flow rate. The bipolar electronic design and the 10000 M
Ω
input impedance reduce galvanic formation on the
electrodes and minimize coating problems. The isolated current output provides an universal signal to recorders, valves, process
control and data acquisition devices. The open collector frequency output is compatible with all powered flow controllers.
