เครื่องวัดอัตราการไหลของเหลวแบบสนามแม่เหล็กไฟฟ้า (Electromagnetic Flow Meter) DN10-DN150

• Measuring principle

Mag meter works based on Faraday's law, and measure conductive medium with conductivity more than 5 μs/cm and flow range from 0.2 to 15 m/s. An electromagnetic flow meter is a volumetric Flowmeter that measures the flow velocity of a liquid through a pipe. 

The measurement principle of magnetic flow meters can be described as follows: when the liquid goes through the pipe at the flow rate of v with a diameter D, within which a magnetic flux density of B is created by an exciting coil, the following electromotive E is generated in proportion to flow speed v:

E=K×B×V×D

Where:               E－Induced electromotive force                K－Meter constant                B－Magnetic induction density               V－Average flow speed in cross-section of measuring tube                D－Inner diameter of measuring tube

• Introduction

 SUP-LDG electromagnetic flowmeter is applicable for all conductive liquids. Typical applications are monitoring accurate measurements in liquid, metering and custody transfer. Can display both instantaneous and cumulative flow, and supports analog output, communication output and relay control functions.

Stainless steel flow meters have several features and advantages, including:

• Corrosion Resistance: Stainless steel flow meters are highly resistant to corrosion, making them ideal for use in harsh environments, such as chemical processing plants, oil and gas refineries, and wastewater treatment facilities.
• Accuracy: Stainless steel flow meters are known for their accuracy, providing reliable and consistent measurements of fluid flow.
• Durability: Stainless steel is a robust material, which makes these flow meters durable and long-lasting, even under high pressure and temperature conditions.
• Easy Maintenance: Stainless steel flow meters require minimal maintenance, which helps reduce downtime and operating costs.
• Hygienic: Stainless steel is non-porous and easy to clean, making it a suitable material for use in the food and beverage industry, pharmaceutical industry, and other industries that require high levels of hygiene.
• Wide Range of Applications: Stainless steel flow meters can be used to measure the flow of a wide range of liquids and gases, including water, chemicals, petroleum, and other fluids.

• Application

      Electromagnetic flowmeters have been used throughout industries for more than 60 years. These meters are applicable for all conductive liquids, such as: Domestic water, industrial water, raw water, ground water, urban sewage, industrial wastewater, the processed neutral pulp, pulp slurry, etc
