The Signet 2551 Magmeter is an insertion style
magnetic fl ow sensor that features no moving parts.
The patented* sensor design is available in corrosion-
resistant materials to provide long-term reliability with
minimal maintenance costs. Material options include
PP with stainless steel, PVDF with Hastelloy-C, or PVDF
with Titanium. Utilizing the comprehensive line of Signet
installation fi ttings, sensor alignment and insertion depth
is automatic. These versatile, simple-to-install sensors
deliver accurate fl ow measurement over a wide dynamic
range in pipe sizes ranging from DN15 to DN900 (1⁄2 to
36 inches), satisfying the requirements of many diverse
applications.
Signet 2551 Magmeters off er many output options
of frequency/digital (S 3 L) or 4 to 20 mA which are
available on both the blind and display versions. The
frequency or digital (S 3 L) sensor output can be used
with Signet’s extensive line of fl ow instruments while
the 4 to 20 mA output can be used for a direct input to
PLCs, chart recorders, etc. Both the 4 to 20 mA output
and digital (S 3 L) sensor interface is available for long
distance signal transmission. An additional benefi t is the
empty pipe detection which features a zero fl ow output
when the sensors are not completely wetted. Also, the
frequency output is bi-directional while the 4 to 20 mA
output can be set for uni- or bi-directional fl ow using the
display or the 3-0252 Confi guration Tool which connects
to PCs for programming capabilities.
In addition, the display version of the 2551 Magmeter
is available with relays and features permanent and
resettable totalizer values, which can be stored and seen
on the display. Also, the display contains multi-languages
with English, Spanish, German, French, Italian and
Portuguese menu options.
