Product Description

Product Description

 

In the realm of industrial process control, accurate flow measurement is fundamental for ensuring efficient operations, optimizing resource utilization, and maintaining product quality. The Endress+Hauser Proline Promag W 300 Electromagnetic Flowmeter stands as a cutting - edge solution in this domain, offering unparalleled precision and reliability. Endress+Hauser, a global leader in industrial measurement and automation technology, has engineered the Promag W 300 to meet the diverse and demanding requirements of modern industries, from water and wastewater treatment to chemical processing and food and beverage production.

 

Measuring Principle

At the heart of the Promag W 300 is the electromagnetic principle of flow measurement. This principle is based on Faraday's law of electromagnetic induction, which states that when a conductor moves through a magnetic field, an electromotive force (EMF) is induced. In the case of the Promag W 300, the conductive liquid flowing through the flowmeter acts as the conductor, and the flowmeter generates a magnetic field perpendicular to the direction of flow.

 

Flow Measurement Range

The Promag W 300 offers a wide flow measurement range, making it suitable for a variety of applications. It can measure flow rates from as low as 0.1 m/s to as high as 15 m/s, depending on the size of the flowmeter and the specific application requirements. This wide range allows the flowmeter to be used in applications such as water treatment plants, where low - flow rates need to be measured accurately for dosing and control purposes, as well as in industrial pipelines, where high - flow rates are common.

Conductivity Range

The Promag W 300 is designed to measure the flow of conductive liquids. It can accurately measure liquids with a conductivity range of ≥5 μS/cm, making it suitable for a wide variety of liquids, including water, wastewater, and many chemical solutions. However, for liquids with lower conductivity, special versions of the flowmeter are available that can measure conductivity down to 0.5 μS/cm.
