Signet 3-2551-P0-12 Magmeter Flow Sensor, No Display, for pipe sizes from 0.5 to 4 in.

The GF 2551 Magmeter is an insertion style magnetic ?ow sensor that features no moving parts and an integral display.

The 2551 Magmeter measures the flow rate in a full pipe by monitoring the voltage produced when the (conductive) fluid moves through a magnetic field. Output options include a traditional frequency signal, a serial data (Digital (S3L)) output, and a 4 - 20 mA output.
