The Burkert 8045 electromagnetic flow meter is a Burkert insertion flow meter suitable for pipe diameters from 1/2 to 16 inches. Burkert 8045 electromagnetic flow meter are as follows: The piezoelectric element is often made into a circular thin plate that vibrates along its thickness.

The diameter of the thin plate is more than 10 times the thickness to ensure the directionality of the vibration.

The piezoelectric element material is mostly lead zirconate titanate. To ensure that the ultrasonic wave is injected into the fluid at a suitable angle, the element needs to be inserted into the acoustic wedge to form the transducer (also known as a Burkert probe).

Introduction: Type 8045 - Insertion Electromagnetic Induction Flow Meter.

The 8045 Burkert electromagnetic flow meter consists of an electronic module with a backlit display, operation buttons, and a PVDF or stainless steel sensor. Suitable for neutral and mildly corrosive liquids with conductivity greater than 20 μS/cm, DN06-DN400.

Equipped with a 4-20mA signal output port and a digital output port (pulse output by default).

Some versions offer two relay output ports and one digital input port. Flow rate is calculated by two independent accumulators. Available interfaces: - G2” interface for PVDF sensors - G2” or clamp interface for stainless steel sensors.

The stainless steel sensor version is suitable for high-pressure (PN16) and high-temperature applications (110°C).

The C22 alloy electrode version is suitable for corrosive liquids (chemicals) and seawater applications. Burkert electromagnetic flowmeters are frequently used in current process industries due to their many advantages, such as corrosion resistance and wear resistance. However, strict adherence to usage rules is crucial during the use of electromagnetic flowmeters.

Improper operation or improper installation will inevitably lead to inaccurate measurement results, negatively impacting the entire measurement process. Therefore, this article analyzes the factors influencing measurement errors of electromagnetic flowmeters and seeks effective solutions.

When measuring, the temperature, density, and external pressure of the test substance do not affect the Burkert electromagnetic flowmeter. Furthermore, the internal components of the flowmeter are resistant to various obstructions, wear, and corrosion, leading to its increasingly widespread use in numerous industries such as chemical, pharmaceutical, and power.

On the other hand, when using the 8041 and 8045 models of the Burkert electromagnetic flowmeter (00449673 00449671), improper measurement methods will inevitably lead to errors in the entire measurement process, negatively impacting the measurement results.

Therefore, this paper will study the factors affecting the error of electromagnetic flowmeters and propose several solutions based on these factors.

I. Factors Affecting Measurement Error of Burkert Electromagnetic Flowmeters (I) The Influence of the Test Liquid The first factor is the influence of the test liquid on the measurement.

If the liquid cannot fill the entire measuring tube or contains abnormalities, the back pressure of the entire test tube will be insufficient. Inaccurate installation of the flowmeter sensor can also cause measurement errors.

The measurement error will dynamically change with the amount of air bubbles and the movement of the liquid within the tube.

If the gas flow inside the flowmeter is stratified or wavy, it will introduce more significant errors into the measurement results, meaning the measured value will not match the actual result. be blocked by the gas phase, resulting in output fluctuations.

Furthermore, if the liquid in the measuring tube becomes increasingly insufficient, it will also cause severe output fluctuations;.

In severe cases, the electrode may even be exposed above the liquid surface, resulting in an overfilling output. Secondly, the presence of powdery or particulate solids in the measuring tube of the Burkert electromagnetic flowmeter can lead to a solid phase phenomenon in the liquid.

This phenomenon can cause slurry noise, electrode contamination, and lining wear, ultimately resulting in inaccurate measurement results. Finally, the presence of liquid crystallization can also cause significant errors in the measurement results of Burkert electromagnetic flowmeters, and such flowmeters should be used with caution.

Some easily crystallizing chemicals will produce normal measurement results at normal temperatures. Generally, the conduits used for liquid transfer are equipped with heat preservation functions, so liquids generally do not crystallize.

However, the flow meter sensor's conduit lacks this function, so when the liquid temperature drops in the conduit, it easily forms a crystal on the inside. Choosing other flow meter models will also present this problem.

Therefore, when no better option is available, an annular electromagnetic flow meter should be selected, and the insulation function of its upstream pipeline should be strengthened to ensure that the entire pipeline system is easy to disassemble and to easily resolve the crystallization phenomenon.

(II) Inappropriate Electromagnetic Flow Meter Selection: The electrodes and lining materials of the Burkert electromagnetic flow meter are in direct contact with the liquid being measured.

The electrode and lining materials should be selected according to the characteristics of the liquid being measured, such as corrosiveness and abrasiveness, as well as the operating temperature. Improper selection will cause problems such as rapid adhesion, corrosion, scaling, wear, and lining deformation, leading to measurement errors.

Therefore, this should be given high priority during equipment selection. Additionally, if the conductivity of the measured liquid is close to the lower limit, reading fluctuations may also occur.

Because the lower limit value specified in the manufacturer's instrument specifications is the lowest value that can be measured under various favorable operating conditions, and actual conditions are unlikely to be ideal, we have encountered situations where low-concentration distilled water or deionized water, whose conductivity is close to.

the lower limit value of 5 specified in the specifications of the split-type electromagnetic flowmeter, still exhibits output fluctuations during use.

It is generally believed that the lower limit value of conductivity that can be measured stably is 1 to 2 orders of magnitude higher. It is recommended to consult the relevant manual to clarify the conductivity of the liquid being measured before using the product.

(III) Electromagnetic Interference The electromagnetic interference of Burkert electromagnetic flowmeters can be divided into two main categories according to the transmission path: conducted interference, which mainly refers to the interference signals generated by electronic equipment interfering with each other through conductive media or common power lines; and radiated interference, which.

refers to to the interference signals generated by electronic equipment being transmitted to another electrical network or electronic equipment through space.

From the perspective of the interfered sensor, interference coupling can be divided into two main categories: conducted coupling and radiated coupling. When a signal requires a long transmission line, it is easily interfered with during transmission, causing distortion or loss of signal quality.

The interference mainly includes electromagnetic induction interference from the surrounding electromagnetic field; and crosstalk between transmission lines caused by distributed capacitance and mutual inductance when two or more signal lines of different strengths are close together.

II. Strategies for solving measurement errors in Burkert electromagnetic flowmeters: (I) Reducing the influence of air bubbles on measurement: When the measurement result fluctuates, immediately cut off the excitation circuit current of the magnetic field.

If the instrument still displays an unstable reading, it indicates that the error is mostly due to air bubbles. After confirming that a large number of air bubbles are affecting the measurement results of the electromagnetic flowmeter, relevant solutions need to be found.

If it is determined that the large number of air bubbles are caused by the installation location, such as the Burkert electromagnetic flowmeter being installed at a high point in the pipeline system and storing gas or external air intake causing the flowmeter to shake, changing the installation location is.

the most effective solution.

However, in many applications, the diameter is large or the installation location is not easy to change.

It is recommended to install a gas collection bag and exhaust valve upstream of the Burkert electromagnetic flowmeter to remove excess gas, reduce the factors affecting the measurement results, and ensure the accuracy of the measurement.

(II) Zeroing the sensor: To eliminate the orthogonal interference generated by electromagnetic interference, two wires are connected to the two ends of the potentiometer at one electrode. The lead wire on the other electrode and the middle end of the potentiometer are connected to the inlet section of the converter.

At this time, two closed loops are formed, generating their own induced electromotive force and current. The two currents are applied to the input resistor of the converter through the middle end of the potentiometer. At this time, the directions of the two currents are opposite.

Before use, adjust the position of the contact point at the middle end of the potentiometer so that the two currents are equal in magnitude and can cancel each other out.

a suitable Burkert electromagnetic flowmeter model: Based on the principle of a conductor cutting magnetic lines of force, the faster the conductor cuts, the stronger the signal.

To ensure measurement accuracy, we generally select a flow velocity of not less than 0.5 m/s (generally, the economical flow velocity is 1-3 m/s). Correct selection can also save users investment.

According to the working principle of the electromagnetic flowmeter, the medium must be a conductor, therefore, the conductivity must be not less than 5 µS/cm. Too low a conductivity will cause the electromagnetic flowmeter to malfunction.

Select the correct lining material based on the temperature, acidity, alkalinity, and corrosiveness of the medium.

Both the electrodes and the lining are in contact with the medium, so the correct electrode material for the German Burkert electromagnetic flowmeter must be selected based on the acidity, alkalinity, and corrosiveness of the medium.
