One of the most commonly used flow measuring device is the magnetic flow_meter also known as electromagnetic flow_meter and referred to as'mag meter'.It is one of the modern innovations that incorporates electronic devices and does not have any moving parts.It is the perfect solution for wastewater applications or other dirty water based liquid and also where low maintenance and low pressure drop are required.This device will not work with distilled water,hydrocarbons and other non-aqueous solutions.The physical principle behind the operation of electromagnetic flow-meter is based upon Faraday's law of electromagnetic induction.
Types of Electromagnetic Flow Meters
There are different types of magnetic flow_meters designed to meet different industrial requirements.Some are simple and cost effective,while a few are sophisticated and expensive.However,your selection should not be based on price and technology,rather it should depend upon the setup you have.Some of the different magnetic flow_meter types include the in line magnetic meter that has superior noise immunity and ceramic detection tubes.These meters offer precise flow measurements and are available in different pipe sizes.Insertion style electromagnetic flow_meters are the latest in bipolar pulsed dc technology and include the best hi-tech features.They are known for their low cost maintenance and long term reliability features.Another type of meter is the low flow magnetic meter which is designed for electrically conductive fluids and chemicals of varying viscosities.
How to Buy an Electromagnetic Flow Meter?
Some of the most important factors that you need to consider while buying an electromagnetic flow_meter are.Determine whether the fluid is water based or conductive,whether it is slurry or abrasive,whether you want remote display or integral,whether you want a digital or an analogue output,check the minimum and maximum flow rate of the device,identify the minimum and maximum process pressure and temperature,determine whether the fluid is chemically compatible with the measuring devices'wetted parts,determine the pipe size and determine whether the pipe is always full or rarely full.
How to Choose an Online Supplier?
It is much easier to buy electromagnetic flow_meters from online stores as there are plenty of suppliers with a trusted online presence.However,when you have made the decision to buy an expensive and complex device like the electromagnetic flow meter you need to buy it from a store that also offers additional services such as installation,application assistance,technical training and field service.If your intention is to buy from a supplier who is located in another country,then make sure that the supplier has a good network of agencies who can offer these services to you in the place where you are located.Even if you are choosing a supplier from another country,make sure that the pricing is competitive enough.
