Electromagnetic Flowmeter Flange Type

Introduction

Flange electromagnetic flowmeter is a flowmeter that tests flow based on Faraday’s law of electromagnetic induction. Flange electromagnetic flowmeter has been used worldwide for more than half a century. The advantages of flange electromagnetic flowmeter are extremely small pressure loss and a large measurable flow range. The ratio of maximum flow to minimum flow is generally above 10:1. The applicable industrial pipe diameter range is wide, up to 3m. The output signal and the measured flow are linear, with high accuracy. It can measure the flow of acid, alkali salt solution, water, sewage, corrosive liquid, mud, ore pulp, pulp and other fluids with conductivity ≥5μs/cm.

Advantages
Advantages and Disadvantages of Flange Electromagnetic Flowmeter:
The main advantage of flange electromagnetic flowmeter is that it has no moving parts, no pressure loss, and extremely low maintenance cost.
The flange electromagnetic flowmeter has a wide range of calibers, from DN15 to DN3000mm, and can measure flow in both directions. The electromagnetic flowmeter has built-in self-diagnosis function, supports data logging/Bluetooth function and multiple output signals.

Compared with other liquid flowmeters, the limitation of flange electromagnetic flowmeter is that it can only be used for conductive liquids. For non-conductive or low-conductive liquids, such as petroleum products, organic solvents, it cannot be used. If there is a strong magnetic field in the surrounding environment, the flange electromagnetic flowmeter will be affected.

Application

Flange electromagnetic flowmeter installation requirements：
Flange electromagnetic flowmeters are widely used in process flow measurement and control of industrial and agricultural production enterprises such as iron and steel metallurgy, water supply and drainage, Water conservancy and irrigation, water treatment, sewage treatment stations (environmental sewage control, chemical sewage, electroplating sewage), paper mills (pulp), mud, petrochemicals, medicine, food, etc.
In the iron and steel metallurgical industry, it is often used for cooling water flow control of continuous casting steel, continuous rolling steel, and steelmaking electric furnaces;
In the field of public utility water supply and drainage, it is often used for finished water and raw water transportation and metering in water plants, and lightning protection functions can be customized, which can be used in areas prone to lightning strikes;
In the pulping process of the papermaking industry, electromagnetic flowmeters involve the flow measurement of pulping, water, acid, and alkali;
In the coal industry, it is used for coal washing metering and pipeline pressure water transportation of coal sludge;
In the food and beverage industry, it is used for filling metering of beer and beverages; in the chemical and petrochemical industries, it is used to measure the flow of corrosive liquids such as acids and alkalis.
