Top rated Radar level transmitter factory: 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.

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.
Application conditions, application conditions generally include calm liquid level, slightly fluctuating surface, turbulent surface, with stirring, with foam and so on. The more complex the conditions, the more interference echoes, and the smaller the actual measured range. In a complex environment, a precision radar with strong ability to deal with interference echoes or an antenna with a larger size should be selected.
The electromagnetic wave emitted during measurement can pass through the vacuum, no transmission medium is required, and the anti-interference ability is strong, and it is not affected by temperature, wind, water vapor, water mist, rain, etc. It can be used for liquid level measurement of almost all liquids, and can be continuously measured on-line unattended. Large measurement range, high precision, mature technology and stable performance.
An important part of steam generation is the quality of the steam generated. Maintaining water quality in the boiler within design parameters ensures the highest quality steam possible while minimizing blowdown of the boiler, both of which improve energy and resource management. Continuous or manual blowdown of the boiler minimizes scale accumulation and corrosion resulting from impurities in the water. The blowdown provides a means of accommodating liquid and impurities from the boiler, with the latter facilitating energy recovery through the use of flash steam.
So what can be done about these difficulties? Under the condition of strong dust, on the one hand, the radar with high transmitting energy can be selected, on the other hand, the measurement software with continuous measurement algorithm of wave-loss waiting can be selected. When the radar encounters strong dust, it will not misjudge the measurement result even if the radar loses wave for a short time. After entering the state of continuous measurement algorithm, if the reflection wave of real material surface can be recognized within the set waiting time, the correct measurement value of material surface can be obtained. In the past, only a few foreign radars have this function. At present, there are also domestic radars with this function, and the practical application effect is very good.

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.
When the distance between the liquid level of the measured medium and the electromagnetic wave transmitter is less than 4m, the guided wave radar is selected. If the distance between the liquid level of the measured medium and the electromagnetic wave transmitter is greater than 4m and less than 35m, select the guided wave radar with the guided wave cable. When the distance between the liquid level of the measuring medium and the electromagnetic wave transmitter is greater than 35m, or when the liquid level of the measuring medium is high temperature, high viscosity or solid liquid level, the air-shooting radar should be selected.
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.
