GF Signet 3-2551-P0-22 2551 Magmeter Flow Sensor, 1/2'' to 4'' Pipe, 4-20 mA, with Display and Relays

The Signet 2551 Magmeter is an insertion style magnetic flow sensor that feature 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 fittings, sensor alignment and insertion depth is automatic. These versatile, simple to install sensor deliver accurate flow measurement over a wide dynamic range in pipe sizes ranging from 1/2" to 36", satisfying the requirements of many diverse applications.

Signet 2551 Magmeters offer many output options of frequency/digital (S3L) or 4 to 20 mA which are available on both the blind and display versions. The frequency or digital sensor output can be used with Signet's extensive line of flow instruments while the 4 to 20 mA output can be used for a direct input into PLCs, chart recorders, etc. Both the 4 to 20 mA output and the digital sensor interface is available for long distance signal transmission. An additional benefit is the empty pipe detection which features a zero flow output when the sensors are not completely wetted.

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.
