                                     Mag Flow Meter With Carbon Steel DN800 Rubber Liner PN10 Flanges

1. Introduction

MLF electromagnetic flowmeter is based on Faraday's law of electromagnetic induction and consists of sensors and converters. Used to measure the conductivity of a liquid or solid. Generally, its conductivity should be greater than 5μS/cm (the conductivity of tap water, raw water is about 100~500μS/cm). it can also be used to measure various media such as acid, alkali, brine, pulp or pulp and other medium. But these medium can not contain a large number of magnetic substances and bubbles.

MLF electromagnetic flowmeter is an instrument to measure liquid fluidity. Widely used in metallurgy, chemical, paper, environmental protection, petroleum, textile, food, urban management, water plants and other industries of flow measurement.

9. 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.
