Measuring principle: Based on Faraday's law of electromagnetic induction, when the conductive liquid cuts the magnetic line of force movement in the magnetic field, it will generate induced potential in the conductor, and the flow rate of the liquid is calculated by measuring this induced potential.

Model specifications: common models such as MF350, etc. The specific model may vary depending on the manufacturer.

Technical Parameters

1. Measuring range: usually 0~5000m³/h, suitable for large flow rate liquid measurement.
2. Pipe diameter: 350mm, suitable for the installation of large caliber pipes.
3. Accuracy: ±0.5%, able to meet the needs of precise measurement.
4. Temperature range: Depending on the material and design, the working temperature range may vary, but it can generally work in the temperature range of -25℃~60℃ or wider.
5. Pressure range: The working pressure range is generally 0~4MPa, capable of withstanding certain pressure.

DN350 electromagnetic flowmeter is widely used in the following fields:

1. Industrial production: such as petrochemical, metallurgical, chemical and other industries flow measurement, can measure the flow of crude oil, natural gas, water and other media.
2. Water conservancy engineering: used in large-scale water conservancy projects, hydropower stations and other occasions of flow measurement, such as rivers, lakes, reservoirs and other liquid media measurement.
3. Environmental monitoring: In the field of environmental monitoring, it is used for flow measurement in wastewater treatment, atmospheric monitoring and other occasions to ensure compliant emissions.
4. Pipeline Conveyance: Ensure safe and stable conveyance in flow measurement in oil and gas pipelines and other applications.

Use and Maintenance

Installation requirements: DN350 electromagnetic flowmeter should be installed to meet the requirements of a certain straight pipe section to ensure measurement accuracy. At the same time, it should be avoided to be installed near the equipment with strong electromagnetic field to prevent interference.

Maintenance: Regular inspection and maintenance of the flowmeter, including checking whether the wiring is good, whether the environment around the instrument is clean and so on. For easy to stain the electrode or easy in the measuring pipe wall precipitation, scaling of the medium, should be made regularly for scaling, cleaning.
