Georg Fischer Signet Magmeter ORCA Flow Sensor Type 2551 32551P042

The Georg Fischer Signet ORCA Type 2551 Magmeter Flow Sensor (32551P042)

is a high-precision insertion-style electromagnetic flow sensor designed for accurate measurement of conductive liquids in industrial applications. It is part of the widely used Signet 2551 series, known for reliability, durability, and low maintenance.

This sensor operates on the electromagnetic (magmeter) principle, where the flow of conductive liquid generates a voltage proportional to flow velocity. Because it has no moving parts, it offers long service life and minimal wear, even in harsh environments.

The ORCA variant integrates advanced sensing technology and is constructed using corrosion-resistant materials such as polypropylene and stainless steel, making it suitable for aggressive fluids and demanding industrial conditions.

It is designed for easy installation into pipelines and supports automatic alignment through compatible fittings. The sensor provides stable and repeatable flow measurements across a wide range of applications, from water treatment to chemical processing.
