                                    Digital Food Grade Milk Refrigerant Electromagnetic Flowmeter Sanitary Grade Mag Flow Meter

1. Introduction

MLF electromagnetic flow meter, composed of sensor and converter, works based on Faraday’s law of electromagnetic induction law. It is used to measure electrical conductivity of liquid or solid. Generally, the electrical conductivity should be over 5υS/cm(electrical conductivity of tap water, raw water is about 100～500υS/cm),It can also be used to measure various media like acid, alkali, saline solution, paper pulp or pulp and so on. But these media can’t contain a lot of magnetic materials and bubbles.

MLF electromagnetic flow meter is a kind of instrument which is used for measuring the flow conductivity liquid. The meter is widely used in flow measuring of Metallurgy, Chemical Industry, Paper Industry,Environmental Protection, Oil Industry, Textile Industry, Food Industry and City Administration, Water Works,etc.

8. Advantages & Disadvantages

There are numerous benefits to using electromagnetic flowmeters to perform fluid flow measurements. They are generally non-invasive and have no moving parts, reducing the risk of breakdowns and the frequency of repairs. A decrease in flowmeter pressure is also usually no greater than that of an equivalent pipe length, reducing the piping costs. Some of the other major advantages provided by magnetic flowmeters include:

• Power usage is relatively low, with electrical power requirements as low as 15 watts for some models.
• They are mechanically obstructionless and can be equipped with abrasion-resistant liners, making them effective for measuring slurries and other erosive fluids.
• They are capable of dealing with most kinds of acids and bases, as well as water and water-based solutions, due to lining materials that are both insulators and have corrosion resistance.
• Relatively small amounts of electrode metals are needed for magnetic flowmeters.
• They can measure both very low flows and very high volume flow rates, with a minimum diameter of roughly 0.125 inches and a maximum volume of up to 10 cubic feet.
• They can usually measure multidirectional flow, either upstream or downstream.

Despite these advantages, magnetic flowmeters also present certain difficulties for flow rate measurement. These flowmeters are only effective on conductive fluids, and materials such as unmixed hydrocarbons and gases cannot be measured. However, magnetic materials themselves may also present problems, as hydrodynamic effects can alter the normal flow pattern and disturb the velocity rate enough to interfere with operations. Depending on their size and capacity, magnetic flowmeters can be relatively heavy, and those with higher corrosion and abrasion resistance can be expensive.
