Product Description

The inteligent electromagnetic flowmeter is an inductive instrument used for measuring the volumetric flowof conductive media, based on Faraday's law of electromagnetic induction. A pair of detecting electrodesare installed on the pipe wall, perpendicular to both the axis of the measuring pipe and the magnetic fieldlines. When the conductive liquid moves along the axis of the measuring pipe, it cuts through the magneticfield lines, generating an induced electromotive force. This induced voltage is detected by the electrodesand its magnitude is proportional to the flow rate.

This flowmeter can measure the volumetric flow of general conductive liquids as well as strongly corrosiveliquids such as strong acids and bases, and homogeneous liquid-solid two-phase suspensions like slurrymineral slurry, and pulp, it is widely used for flow measurement in industries such as petroleum, chemicalmetallurgy, textile, paper, environmental protection, food, as well as in municipal management, water con.servation, and river dredging.

Key Features:

 

1. Compact Integration: Combines both sensor and transmitter in a single unit, simplifying installation in space-constrained environments and highly demanding industrial settings.

2. Precision Performance: Equipped with advanced electromagnetic technology, the flowmeter ensures accurate flow measurements for conductive liquids across a wide range of applications.

3. Robust Design: The flowmeter is engineered to withstand harsh industrial environments, including exposure to chemical agents, temperature variations, and abrasive materials.

4. User-Friendly Interface: Features a digital display for easy monitoring and customizable settings, allowing operators to optimize performance in real-time.

5. Maintenance-Free: Designed with no moving parts, this flowmeter guarantees long-term reliability with minimal upkeep, making it an ideal choice for industries with stringent operational demands.

Product Selection Guide for Electromagnetic Flowmeters
 

1. Range Determination:

1. (1) Importance of Selection: Proper selection of the flowmeter is crucial for its application. Incorrect selection and installation account for two-thirds of all instrument failures. Pay special attention to the operating conditions.

2. (2) Material Selection: Choose the lining and electrode materials based on the fluid to be measured, including its highest temperature, normal operating temperature, and lowest temperature.

3. (3) Pipe Diameter Selection: Select the pipe diameter based on the maximum flow rate, normal flow rate, and minimum flow rate.

4. (4) Range Appropriateness: The flowmeter range should be greater than the expected maximum flow rate. The normal flow rate should be slightly more than 50% of the flowmeter's full scale.

5. (5) Maximum Working Pressure: Ensure the actual maximum working pressure is less than the rated working pressure of the flowmeter.

6. (6) Additional Features: Choose any additional functions and requirements as needed by the manufacturer's production specifications.

7. (7) Economic Flow Rates:

1. For clean water, the optimal flow rate is 1.5-3 m/s.

2. For solutions prone to crystallization, a higher flow rate of 3-4 m/s is recommended to prevent adhesion and sedimentation through self-cleaning.

3. For abrasive fluids like slurry, a lower flow rate of 1.0-2 m/s is advisable to reduce wear on the lining and electrodes.

4. Actual application rarely exceeds a flow rate of 7 m/s, and 10 m/s is even rarer. For flow rates below 0.3 m/s, a reduction pipe should be used to increase the flow rate.

8. (8) Split Type Considerations:

1. The distance between the sensor and the transmitter should be as short as possible.

2. Excessively long cables are prone to signal interference due to distributed capacitance, generally limiting the distance to less than 30 meters.

Applications:

This electromagnetic flowmeter is highly versatile, suited for corrosive fluids such as strong acids and alkalis, as well as liquid-solid suspensions like slurry and pulp. It is commonly used across industries including oil & gas, chemical processing, metallurgy, textiles, paper production, environmental protection, food processing, municipal management, and water resources management.
