Depending on where you work and what terminology is used, the magnetic flow meter may also be called an electromagnetic flow meter. The Rosemount magnetic flow meter is found in a wide range of industries and applications, and it is an ideal option for many different operations due to its dependability, reliability and long duty cycle.
Important Reasons to Choose a Mag Meter
The Rosemount magnetic flow meter is a bi-directional meter, which means it can measure the flow of the media through the system in both directions. As this is not possible with many of the other flowmeter designs, it can be a cost-effective choice when media must flow through the system bi-directionally.
In addition to this important difference, the magnetic flow meters are also a good option in applications where there are either very low volume flow or very high volume flow rates. This wide scope of flow rate volumes means these meters can be used in oil and gas refineries, wastewater processing facilities as well as in production and process applications.
The Measurement Process
The Rosemount magnetic flow meter is designed to be an in-line meter with the sensors placed within the pipe and directly in the media. The transmitter for the flow meter is positioned above the meter, translating the induced voltage measurements into data.
The flow meter generates a magnetic field in the pipe, and the media in the pipe moves through this consistent field. As the conductive media flows through the field, there is a voltage signal that is generated, which increases as the speed of the media increases.
Without any interior parts and components to obstruct the flow, the mag meter is highly accurate. They are limited to use with conductive types of media, but they are an ideal choice when there is aggressive, corrosive or abrasive types of media.
