Description
The Signet 2551 Magmeter is an insertion-style magnetic fl ow sensor. The patented
sensor design is available in a variety of corrosion-resistant materials to provide long-
term reliability and minimal maintenance costs. Wetted material combinations include
PP/316 SS, PVDF/Hastelloy-C and PVDF/Titanium. The 2551 installs quickly and
securely into a wide selection of fl ow fi ttings to deliver accurate fl ow measurement in
pipe sizes ranging from DN15 to DN900 (½ in. to 36 in.).
Signet 2551 Magmeters are available with a frequency output or Digital (S
for use with the Signet 9900-1BC Batch Controller, 8900 Multi-Parameter Controller
or 9900 Transmitter, or with a 4 to 20 mA output for a direct input to a PLC, SCADA or
telemetry system.
All 2551 Magmeters feature empty pipe detection and LED-assisted diagnostics.
The Signet 3-0252 Confi guration Tool set-up tool is available to customize every
performance feature in the 2551 to adapt it to the specifi c application requirements.

    General Installation and Grounding Tips Sensor conditioning The Magmeter output signal may be unstable immediately after installation. Allowing the sensor to soak in a full pipe (or in any container of water) for 24 hours will stabilize the performance. • Very low conductivity fl uids may require a longer conditioning period. (The Magmeter will not operate properly in fl uids where the conductivity is less than 20 μS/cm.) Grounding The 2551 Magmeter is unaffected by moderate levels of electrical noise.
