1.working principle:

The magnetic flow transmitter is a flow meter that uses the electromagnetic principle to measure the flow of liquid fluid. The equipment involves no moving parts and is therefore very reliable and requires minimal maintenance. It can measure the flow of conductive liquids, including waste water, sewage, pulp, mud and dirty liquids, etc.

When a conductive liquid flows through the magnetic field generated by the emitter, an electric current is generated. According to Faraday’s principle, the induced voltage is proportional to the flow rate of the liquid. The transmitter converts this voltage into a 4-20mA output signal, which can be used to display and control the flow of liquid.

This type of flow transmitter offers several advantages over other flow measurement devices, including independence from fluid pressure, temperature, and viscosity. Since the device has no moving parts, it generates less wear and noise, resulting in a longer lifespan than other flow measurement technologies.

To sum up, the flow transmitter is a highly reliable and effective device for measuring the flow of conductive liquids using electromagnetic principles. It is especially suited for use in harsh industrial and process environments where precision and durability are critical. For these reasons, magnetic flow meters are a popular choice for industrial applications and are found in a range of industries including chemical processing, food and beverage, oil and gas, and wastewater treatment.

2.Applications:

Magnetic flow meters are widely used in various industries to measure the flow and volume of conductive liquids. These devices are commonly used in water and wastewater treatment plants, food and beverage production, chemical processing and many other industrial applications.

One advantage: the ability to accurately and reliably measure liquid flow even in harsh environments where traditional methods such as mechanical flow meters can be damaged or unreliable. These transmitters are also low maintenance, with no moving parts or obstructions to prevent fluid flow.

Another advantage: It is compatible with a wide range of fluids, including corrosive and abrasive fluids that can damage other types of flowmeters. The sensors can handle liquids of different viscosities as long as they are conductive.

A third advantage: It can improve operational efficiency by providing real-time data on fluid flow. This data can be used to optimize processes, reduce waste and improve overall productivity.

The fourth advantage is: it has a variety of output methods: pulse output, 4-20Ma output, MODBUS communication protocol, Hart protocol.

3. Classification:

※ Insertion type flow transmitter, which consists of a magnetic sensor inserted into the fluid. This type of transmitter is very suitable for use in large pipelines or open channels, with low cost of use, simple installation and high accuracy.

※ Integrated online flow transmitter, which is directly installed in the flow pipeline. This type of transmitter is best suited for applications with low flow rates or where the fluid is abrasive or corrosive. In-line flow transmitters are also typically more compact than insertion-type flow transmitters, making them easier to install and maintain.

※ Separate online flow transmitter, the sensor is installed in the pipeline, the converter and the sensor are separated (the standard configuration is 10*2 cable, but the cable length can be customized). This type is more suitable for installation in deep wells or sites with relatively high pipeline positions, especially in deep wells, and can be made with IP68 protection level, so that if there is water in the deep well, it will not affect the normal operation of the instrument.

6.Lining Options:

The selection of the lining of the electromagnetic flowmeter is very important: according to the characteristics of the measured liquid, such as the temperature of the medium, corrosiveness (PH value), the liquid contains impurities, etc., to select the most suitable lining material is to ensure that the flowmeter The working life is the key to measurement accuracy.
Available lining materials are as follows:
