Introduction of Electromagnetic Flow Meter for Large Pipe

An electromagnetic flow meter for large pipes can be used with display, recording instruments, integrators or regulators to detect, integrate, adjust and control the flow. It is not suitable for the measurement of non-conductive liquids, gases and steam. It is used to measure the flow of almost all electrically conductive liquids, as well as mud, paste and slurry. The premise is that the measured medium must have at least a certain small conductivity. Temperature, pressure, viscosity and density have no effect on the measurement results. As long as the appropriate pipe lining material and electrode material are selected, it can also be used to measure corrosive media. Solid particles in the medium will not affect the measurement results.electromagnetic flow meter

Applications of Electromagnetic Flow Meter for Large Pipe

An electromagnetic flow meter for large pipe is mainly used to measure the volume flow of large-flow conductive liquids.

Water supply system:  An electromagnetic flow meter for a large pipe is installed on the water supply pipeline. It can monitor the flow of water supply in real time to ensure the stable operation of the water supply system.

Drainage system: used to monitor the flow of sewage in urban drainage pipes. It helps relevant departments to grasp the drainage situation and respond to extreme weather such as heavy rain in a timely manner.

Sewage treatment plant: It can accurately monitor the flow of sewage and provide data support for the adjustment and control of sewage treatment processes. It can ensure that the sewage treatment effect meets environmental protection requirements.

Chemical production: used to measure the flow of conductive liquids such as various acids, alkali, and salt solutions in the chemical production process. Such as sulfuric acid, sodium hydroxide, hydrochloride acid, etc. It helps companies grasp the material consumption in the production process.

Slurry transportation: Electromagnetic flow meters for large pipe flow meters are used to measure the flow of slurry. Such as iron ore slurry, copper slurry, etc. It ensures the stability of the slurry transportation process and provides guarantees for subsequent mineral processing and smelting processes.

Liquid food production: It is used to measure the flow of liquid food in the production process. Such as juice, milk, beverages, etc. It ensures the hygiene of the production process and product quality, and meets food safety requirements.

Pulp transportation: An Electromagnetic flow meter for large pipe is used to measure the flow of pulp and help control the delivery volume of pulp. It ensures the stability and quality of paper production.

Sugar liquid transportation: It is used to measure the flow of sugar liquid in the sugar-making process, such as sugarcane juice, syrup, etc., to provide data support for the control and optimization of the sugar-making process.

What is the Difference between a Turbine Flow Meter and an Electromagnetic Flow Meter?

Sino-Inst has more than 20 years of instrument measurement experience. Based on our experience, we have sorted out the differences between turbine flowmeter and electromagnetic flowmeter.

  1. Working principle

The turbine flow meter rotates the turbine by impacting the turbine blades with fluid, and the speed of the turbine changes with the flow rate.

The electromagnetic flowmeter works based on Faraday’s law of electromagnetic induction. When a conductive fluid flows through a magnetic field perpendicular to the flow direction, an electromotive force is induced in the conductor, and its magnitude is proportional to the flow rate of the fluid.

  1. Measuring medium

The turbine flowmeter cannot measure conductive liquids, liquids with high viscosity and liquids with many impurities. It is mostly used to measure oils.

The electrical flowmeter can measure conductive liquids, liquids with high viscosity and liquids containing impurities. It can measure slurries, pastey, acid and alkali corrosive liquids.

  1. Composition material

The turbine flowmeter uses stainless steel or PE to measure corrosive liquids.

The electromagnetic flowmeter uses a custom lining material. As long as the medium is compatible with the custom lining material. Then the electromagnetic flowmeter can measure other corrosive media.
