Endress + Hauser Promag 33F Flowmeter

The Endress+Hauser Promag 33F is a compact electromagnetic flowmeter designed for accurate measurement of electrically conductive liquids in chemical processing, water treatment, industrial manufacturing, and process control applications. The Promag 33F combines a robust flow sensor with an integrated transmitter, providing reliable flow measurement with no moving parts, minimal maintenance, and virtually no pressure loss. It is particularly suited for corrosive liquids and high-temperature process media.

Function

The Promag 33F operates using Faraday's Law of Electromagnetic Induction. As a conductive liquid flows through the magnetic field generated by the sensor, a voltage proportional to the flow velocity is induced and measured by the transmitter. This provides highly accurate flow measurement without mechanical wear, restrictions, or moving components in the flow path.
