Level measuring devices manufacturer from China: Advanced Radar Level Measurement: The constant progress of innovation continues to push the limits of radar level measurement, propelling this technology into areas of capability and pertinence. As industries undergo transformations and integrate the Industrial Internet of Things (IIoT) into their operational processes radar devices have evolved to meet these changing demands. Integration with IIoT- Leading the Way to Industry 4.0 One of the transformative developments in radar level measurement is the seamless integration of Industrial Internet of Things (IIoT) capabilities into radar devices. These radar sensors equipped with IIoT features have become important components in Industry 4.0 initiatives ushering in an era where data driven excellence prevails in operations.

In the measurement circuit of the radar level gauge, when there is additional DC current and voltage, it is DC interference. In severe cases, the measuring instrument will not work properly. The sources of DC interference are as follows: AC interference can be divided into line-to-line interference and ground interference. Inter-line interference refers to the AC voltage between the output ends of the radar level gauge (compensation line) under external influence. This interference is also known as lateral, common mode or common mode interference. Generally speaking, the line-to-line interference voltage can reach several millivolts or even tens of millivolts.
There is AC interference and the voltage is high. For example, for the radar level meter used in the production line, the power supply requirement is 24VDC (typical value), but in the on-site measurement, it is found that the power supply is displayed as 27.2V, which is significantly higher than 24VDC, resulting in a large measurement result and even a radar level meter. crash phenomenon. The installation position of the radar level meter is incorrect, which leads to deviations in the measurement. For example, the accumulation of aggregates in the transfer bin is a “mountain”-shaped cone, but only one radar level meter is installed near the discharge port of the return belt. , the installation position is too close to the discharge opening of the return belt, and at the same time, it is too far from the discharge opening of the feeding belt on both sides. Just below the radar level meter is the drop point of the return belt. If the distance is too close, the aggregate in the falling process will interfere with the radar level meter and form false reflections.
Rod antenna: generally used in strong corrosive environments, with weak anti-interference ability and small range; Flare antenna: stronger anti-interference ability, suitable for more complex environments. The larger the bell mouth, the more concentrated the energy, and the larger the measuring range; Parabolic antenna: the focusing effect is stronger than that of the bell mouth, the anti-interference ability is the strongest, and the range is the largest.
The key components are made of high-quality materials, which have strong corrosion resistance and can adapt to highly corrosive environments. Low power consumption, can use solar power to supply power, no need to build water level wells, adapt to various geographical environments, no impact on water flow, and more convenient installation and maintenance. The parameter setting is convenient, and the false echo from the liquid surface to the antenna can be automatically identified by the software carried by itself to eliminate the interference.
The performance of any level technology relative to instrument induced errors, calibration nuances, and vulnerabilities to process dynamics can have an immediate and adverse impact on fuel consumption. Seamless response to changes in demand and reducing maintenance associated with the instrumentation or damage to hardware are residual benefits that have their own financial ramifications; these aspects should also be considered when implementing any technology. In addition to the “open” or deaerating feedwater heater, the more common shell and tube heat exchangers/condensers can be found in larger scale steam generation cycles where their costs are offset by gains in thermal efficiency. The effectiveness of a shell and tube heat exchanger in transferring energy is contingent, barring hardware anomalies, on accurate level control.

In the process of cement production, material level detection and material level alarm control play an important role from mining and crushing to storage and packing of finished cement. But because of the complex working conditions of cement plant, radar level meter has no small difficulty in measuring. Today, I would like to talk with you about specific difficulties and solutions. First cement plant material for measurement in the dust under the condition of particularly large, especially some pneumatic feed bin, involves the kinds of materials, material particle size is differ, dielectric constant is different also, such as broken limestone, raw meal, clinker, fly ash, coal, cement, the level of the bunker, it is very difficult to accurately measure Especially fly ash bin with low dielectric constant.

Working principle: Working principle of radar level gauge: UHF electromagnetic waves are transmitted to the liquid level of the container under test through the cable or antenna. When the electromagnetic wave touches the liquid level and is reflected back, the instrument detects the time difference between the initial wave and the echo, thereby calculating the liquid level height. Select guided wave radar or airborne radar according to the dielectric constant and measurement length of the measured medium.
The third case is that, during the commissioning stage of a platform construction, when the liquid level is higher than 3800mm, the radar level meter of the dirty oil tank will frequently jump to 0mm, which leads to the shutdown of the fourth-stage production unit. After on-site inspection, the power supply voltage of the radar level meter transmitter is only 9.5V, which is lower than the working power supply voltage of the radar level meter. By further searching for the cause of the failure, found that when the high liquid level, the voltage at the power supply is 23.7V, the safety gate output drops to 9.7V, judged as a safety gate transmitter failure. After replacing the safety grid, the voltage returns to normal, the cabin radar level meter in the test to rule out the problem.
