Product catalog summary

Introduction
The MFE600 Intelligent Electromagnetic Flowmeter is a precision instrument for industrial applications such as petroleum, chemical, and water management. It offers advanced technology for reliable performance, user-friendly interface, and easy maintenance.

Working Principle
The flowmeter uses Faraday's Law of Electromagnetic Induction to measure flow rate by detecting the induced electromotive force in a conductive liquid. The formula is E = K×B×V×D, where E is the induced force, K is the instrument constant, B is magnetic flux density, V is velocity, and D is the pipe diameter.

Wire Connections
Instructions for integrated and separated wire connections, detailing terminal symbols and functions.

Model Selection and Specifications
Model selection should be done by a technician familiar with site conditions. Specifications include instrument type, pipe diameter, electrode material, lining material, pressure, temperature, protection level, and more.

Installation Guidelines
Guidelines for selecting between integrated and separated types, sensor diameter selection, and maintaining flow velocity. Discusses straight pipeline lengths and pressure loss impact.

Installation Considerations
Proper installation direction to prevent bubbles near electrodes. Flowmeter must operate in full pipe conditions, with adequate space to prevent vibration and stress.

Fluid Conductivity and Sealant Use
Avoid installation where fluid conductivity is uneven. Chemicals should be injected downstream, and sealants should not cover electrode surfaces.

Electrode Material Selection
Choose electrode material based on medium corrosivity, with higher corrosion resistance than pipeline material. Coupon tests recommended for complex media.

The product has backlight and wide temperature-ranged Chinese LCD display. With fully practical function, visual display, easy operation, it saves troubles for on-site installation operation and maintenance. MFE600 can be widely used in industrial fields such as petroleum, chemical, metallurgy, water supply and drainage, steel, coal, paper, food, textile, environmental protection and other municipal administration, water conservancy construction field etc. Working Principle The working principle of Electromagnetic Flowmeter is based on Faraday's Law of Electromagnetic Induction, that is, when the conductive liquid flows through the electromagnetic flowmeter, the induced electromotive force will be produced in the liquid conductor, and the induced electromotive force is directly proportional to the velocity of conductive liquid, magnetic flux density and width of conductor (interior diameter of flowmeter). Such induced electromotive force is detected by a pair of electrodes on the tube wall of the flowmeter, and the rate of flow can be acquired by mathematical operation. The equation of induced electromotive force is as follows: E = K× V× B× D E: Induced electromotive force B: Magnetic flux density D: Interior diameter of measuring pipe http: //www.microsensor.cn Add: No.18,Yingda Road Baoji,P.R.China, Tel: +86 917 3600739/3600832
