Baumer – PF55S

Flow Sensor

Brand : Baumer

The Baumer PF55S Flow Meter is a compact industrial electromagnetic flow sensor designed for precise measurement of volume, flow velocity and media temperature in liquid process applications. Built for industrial environments with robust construction and minimal pressure loss due to its continuous, constriction‑free measuring tube, the PF55S delivers stable and repeatable measurements of flow rates and thermal data, ideal for process control, batching, mixing and resource optimization. It supports media with sufficient conductivity and handles high flow velocities up to 10 m/s, making it suitable for general industrial fluids such as water, chemicals and conductive liquids.

The PF55S is designed for straightforward inline installation with standard process connection options and features reliable electrical interfaces including analog and digital outputs for easy integration with controllers, PLCs and automation systems. Its compact footprint, rugged build quality and compatibility with various pipe diameters make it a versatile choice for industrial flow monitoring projects where accuracy, long‑term stability and low maintenance are required.
