Silver Automation Instruments is a China magnetic flow meter supplier at low price cost also rugged quality. Mag meter for water, sewage, alkali，acid , milk, juice ,slurry flow measurement.
Overview
Magnetic flow meter provides many obvious merits over traditional flow measurement and instrumentation in wide applications. It take measurement of conductive liquid ,even fluids with particles ,such as paper pulp, industry sewage, residential waste water, milk, juice, aggressive chemical solutions and so on.
Magnetic inductive flow meter is made by the flow transmitter and flow sensor; it is a kind of velocity flow meter to detect liquid flow rate in a closed pipelines, and has no moving parts inside mag sensor, so little maintenance work is needed. The good point of inductive flow meter is that it can measure dirty liquid even will solids inside, such as slurry, grease, mud, also the .flow rate measurement is not affected by the liquid properties, such as temperature, viscosity ,and density.

Principle
Faraday’s Law of Electromagnetic Induction is used by magnetic flowmeters for determining the way liquid flows in a pipe. A magnetic field is produced in a mag flowmeter and routed into the liquid that flows through the pipe. According to Faraday’s Law, when a conductive liquid flows through the magnetic field, it causes electrodes found on the walls of the flow tubes to sense the voltage signal. With the fluid moving faster, there’s a more voltage generation in proportion to how the flowing liquid moves. To determine liquid flow, the voltage signal is processed by the electronic.
The mag meterr technology is different from other flowmeter technologies it that it produces signals which are flow-linear. For that reason, the magnetic flowmeters are associated with around 20:1 or are better without compromising accuracy. They are up to 23% of all the sold flowmeters. More details: [

Advantages and Disadvantages of magnetic flow meter.
Electromagnetic flowmeters, widely used in industrial applications, offer key benefits but also have some limitations.
A major advantage is their ability to measure conductive liquids—including corrosive, abrasive, or slurry fluids—with high accuracy and minimal pressure drop, as there are no moving parts or obstructions. They provide a linear output and are effective over a wide flow range. Additionally, they are highly durable with proper lining and electrode material selection.
However, a significant drawback is that they cannot measure non-conductive fluids, such as hydrocarbons, oil or steam. They also generally require a minimum conductivity threshold (typically >5 μS/cm) for reliable operation. Another challenge is their need for a fully filled pipe to ensure accurate readings.
The SHD magnetic flow meter ensures fast delivery, easy compatibility, and significant cost savings while delivering accurate and stable performance. Perfect for industrial applications requiring a budget-friendly replacement without compromising quality.

Industrial Applications of Magnetic Flowmeters: From Wastewater to Chemicals
The versatility of magnetic flow meters makes them indispensable across numerous industries. Their robust design is perfectly suited for challenging fluids and environments: Water & Wastewater: They are the industry standard for measuring raw sewage, sludge, treated effluent, and potable water during processing and custody transfer.
Chemical Processing: Their corrosion-resistant liners make them ideal for handling aggressive media, from acids like hydrochloric acid (HCl) to caustics such as sodium hydroxide (NaOH).
Mining & Pulp and Paper: They excel at measuring abrasive slurries, process water, and heavy media flows without wear or clogging.

Slurry Magnetic Flow Meter ] Food & Beverage: Sanitary models are used for measuring liquids like juices, milk, and process water, ensuring hygienic and reliable operations.
It is not proper to operate a magnetic flowmeter close to its electrical conductivity limit due to the risk of the flowmeter turning off. Keep space to change composition and conditions of operation which can change the liquid’s electrical conductivity.
Typical electromagnetic flowmeter applications are sized such that maximum flow velocity is around 2-3 meters each second. Differences in pressure constraints and/or conditions of processes may prevent the application of this over-all guideline. For instance, a larger magnetic flowmeter may be required for gravity-fed pipes to limit the pressure drop which allows the necessary amount of liquid to pass via the magnetic flowmeter with no backing up of the system of piping. This application will lead to a lower liquid velocity unlike a smaller flowmeter if operated at the same rate of flow in the larger flowmwter.
