The Signet 2551 Magmeter is an insertion style magnetic flow sensor that features no moving parts. All versions are constructed of corrosion-resistant materials to provide long-term reliability with minimal maintenance costs. Utilizing the comprehensive line of Signet installation fittings, sensor alignment and insertion depth are automatic. These versatile, simple-to-install sensors deliver accurate flow measurement over a wide dynamic range in pipe sizes ranging from DN15 to DN200 (0.5 to 8 inches), satisfying the requirements of many diverse applications. Signet 2551 Magmeters offer a variety of output options for use with Signet flow instrumentation using a frequency or digital (S3L) output. The blind transmitter (4 to 20 mA output) or digital sensor interface is available for long distance ** transmission. Flow velocity measurement is compensated for temperature via an integrated temperature sensor.
