The structure of DCFL3000A series electromagnetic flow meter


Electromagnetic flow meters are used to measure the flow of conductive media. They are widely used in chemical industry, chemical fiber, papermaking, mining and metallurgy, urban water supply and drainage, environmental protection, water conservancy, steel, petroleum, pharmaceuticals and other industrial fields. It can measure various acids, alkalis, and salts. Solution, production water, lime milk, sewage and various slurries. 

 The structure of DCFL3000A series electromagnetic flow meter

The DCFL3000A series electromagnetic flow meter is an intelligent flow meter with high performance and high reliability. It adopts mature technology, applies high-quality materials, breaks through technical difficulties, and improves product performance indicators. The maximum measurement range can reach DN2200, which can provide customers with Safe and reliable solution.


The structure of the flow meter

The structure of the electromagnetic flow meter is mainly composed of sensors and converters. The sensors include measuring catheters, coils, electrodes, shells, linings, etc.

The structure of DCFL3000A series electromagnetic flow meter


1 measuring catheter

The function of the conduit is to let the measured conductive liquid pass through.

The conduit must be made of non-magnetic materials, such as stainless steel, ceramic, plastic, etc.

Catheter is the flow path of the medium

The pipe bears the rated working pressure


2 coil and magnetic circuit

In order to generate the induced electromotive force, a magnetic field is required, and the coil and the magnetic circuit are mainly used to generate the magnetic field.

When the temperature is different, the temperature resistance grade of the enameled wire of the coil is also different. When the highest temperature is lower than 120℃, it is E-level, if the highest temperature is 180℃, it is H-level. At the same time, note that the lining material should also be compatible with the temperature.。


3 electrodes

Its function is to draw out the induced electric potential signal proportional to the measurement. Electrodes are generally made of non-magnetic stainless steel and are required to be flush with the lining so that the passage of fluid is not obstructed. Its installation position should be in the vertical direction of the pipeline to prevent sediment from accumulating on it and affecting the measurement accuracy.

4 lining

On the inner side of the measuring pipe and the flange sealing surface, there is a complete electrical insulating lining. It directly contacts the liquid to be measured, and its function is to increase the corrosion resistance of the measuring tube and prevent the induced potential from being short-circuited by the metal measuring tube wall. The lining materials are mostly corrosion-resistant, high-temperature, and wear-resistant polytetrafluoroethylene plastics, ceramics, etc.

5.Shell and side ring

It is made of ferromagnetic material and is the outer cover of the excitation coil of the distribution system, and isolates the interference of the external magnetic field.

The shell and side ring are used to protect the coil and electrodes from the environment.

The shell and side ring are used to shield the external magnetic field.

Some calibers and models of housing are part of the magnetic circuit.


6 converter

The induced potential signal generated by the liquid flow is very weak and is greatly affected by various interference factors. The function of the converter is to amplify and convert the induced potential signal into a unified standard signal and suppress the main interference signal. Its task is to amplify and convert the induced potential signal Ex detected by the electrode into a unified standard DC signal.

Converter components: power supply circuit, host circuit, front circuit, display circuit, I/O output current, excitation current circuit, communication interface circuit, etc.

    Case application I The anti-corrosion radar level meter DCRD1000A5&DCRD1000C5 was successfully applied to a chemical project in Inner Mongolia Since Acid-base solutions are extremely corrosive in industrial production measurement applications, the wetted materials of equipment must be anti-corrosion materials. Our high-frequency radar level meter DCRD1000A5 and guided wave radar level gauge DCRD1000C5 are special models for corrosive conditions. Radar antennas are made of PTFE with good anti-corrosion performance, which has good sealing performance, strong corrosion resistance and stable measurement results.Any inquiry about the radar level meter, welcome to contact us at any time.

    The  Features of DCRD1000C series of Guided Wave Radar Level meter (GWR)The guided wave radar level meter is an excellent level meter with advanced technology, excellent workmanship and high precision. When the guided wave radar level meter is working, an electromagnetic pulse signal is emitted, which is transmitted to the liquid level and returned at a constant speed through a probe or a steel cable, thereby simply and accurately calculating the liquid level height.Guided wave radar level meter are currently used in a wide variety of tank containers. It is used to measure the liquid level or level of medium such as aqueous medium, acidic medium, alkaline medium, oil medium, and particles.The guided wave radar level meter (DCRD1000C series) independently developed by Xi'an Dechuan...

    Air purge+Nuzzle ,  Universal joint:The necessary adjunct when measuring the level of bulk solid in silos bins and tanks.When radar level meter measure the level of solid medium, such as grains, cement powders, solid particles,  the solid material  will form a stockpile or hopper in the silo when feeding  or undloading. Then the antenna of the radar level meter need to perpendicularly alignment to the medium surface,  if the material is uneven,  and the heap angle is large then the universal joint flange is needed to adjust the horn angle to aim the charge level.(Due to the inclination of the solid surface it will cause the problem of  echo decay or even the signal loss.)When measuring the bulk solids, there will bring very heavy dust.  we add an air...
