How Magnetic Flow Meters Work

by:Yober     2020-06-01
A magnetic flow meter is technically referred to as an electromagnetic flow meter. These would be the third most usual type of flow mirielle. The other two meters which more common than the magnetic type are good displacement and differential pressure flow m. Commonly, the magnetic meter is known as mag meter. These types of meters operate according to Faraday's law of electromagnetic induction. According to Faraday's law, as the conductor moves through the magnetic field the voltage is stimulated. The liquid flowing through the magnetic field serves as a conductor.As for the magnetic field that created through energized coils that are located on the exterior of the flow tube. When it comes to selecting magnetic flow meters, certain considerations are very important. This entails things just as mounting type, pipe diameter, end fittings, performance specifications, special features, and output options. Other important considerations are the opportunity to monitor media temperature and meter liquids with suspended solids. In general, these varieties of meters differ in accordance to their mounting type and pipe diameter. The available options for mounting always be the non-invasive, insertion type, and in-line. As for the pipe diameter, this refers back to the process pipe, which would be tracked.An in-line flow meter is directly installed throughout the process range. Usually, in order for these kind of installation to occur it should be installed on the straight pipe. On the other hand, the insertion-type devices do not need to be set up on a straight line for a pipe. In most cases, the insertion-type devices require a threaded hole within applying pipe. When it comes to non-invasive electromagnetic flow meters, they shouldn't have a significance about direct-mounting while in the process stream. Additionally, they can be used within the closed piping systems. Involving magnetic flow meter end fittings include: * Clamp * Compression * Flanged * Plain End * Socket Weld * Union * Threaded * Tube End * Hose Nipple The external clamp-on flow meters are non-invasive and use compression fittings in order to tighten them compared to a joint so one of these do not leak. Generally cases, flanges are square or circular and are connected by welding or bolting. As for the plain-end devices, they could be inserted in the end within the connecting water pipe. The interface and electrical output are the two types of options for magnetic flow meters. The available options for electrical output are switch output, frequency, analog voltage and recently available. The options available for the interface are fieldbus, network, digital, and serial. In most cases, a National pipe thread (NPT) is used in combination with threaded motifs. Generally, hose-nipple fittings or tube-end fittings being used with shorter pieces of pipe are generally male threaded. Magnetic flow meters differ in affect on their prime features. Some of them have the capability to measure temperature, level, or density and regularly have features with regard to example visual or audible alarms, in addition to other epidermis features. Magnetic flow meters are also available for sanitary applications also.
