Level measurement instrument supplier factory by Kaidi86: Temperature Compensation- Precision in Any Environment Another advancement in guided radar level measurement technology is the incorporation of mechanisms that compensate for temperature variations. Temperature fluctuations in microwave module circuits can lead to inaccuracies in measuring levels. To tackle this challenge, radar level measurement systems have implemented creative solutions. A crucial aspect of these advancements involves allocating a portion of the radar transmission pulse as a reference pulse. This reference pulse serves as a benchmark for comparing measurements enabling temperature calibration. When temperature changes occur the radar sensor can adjust its measurements accordingly ensuring that environmental conditions have no impact on accuracy. This temperature compensation feature is particularly valuable in applications where significant temperature shifts are common. Industries dealing with temperatures or processes prone to variations, such as petrochemical or food manufacturing sectors, rely on precise measurements. Radar sensors equipped with temperature compensation mechanisms rise to the occasion by delivering reliable results despite changing conditions.

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.
KD-UZC-E type magnetic-sensitive electronic two-color level meter is made of high-quality stainless steel and imported electronic components. The display part adopts high-brightness LED two-color light-emitting tube, which forms a columnar display screen. The level of the measured liquid level is displayed through the red and green changes of the LED light column. High display brightness, long visual distance, clear ruler, large display Angle, adjustable brightness, the product is more visual, intelligent and other characteristics.
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.
What are the characteristics of radar water level meter? All measuring components are designed in an integrated manner, and there is no mechanical wear during measurement. Because the measurement is a non-contact measurement, it is not affected by the physical properties such as the density and concentration of the water body, it is not easy to be washed away by floods, has a long service life and is easy to maintain. The advantages of the radar level transmitter are obvious. The editor warmly reminds that to choose the right one, it is still necessary to meet your own situation.
Level Measurement Considerations: Taking advantage of a specific technology’s ability to reliably address the level measurement in either of these vessels, especially the blowdown flash tank, in a plug-and-play type installation and commissioning format is an easy way to ensure optimal performance. This forgoes calibration, external hardware or inputs. Estimates of up to 49 percent of the energy can be recovered through the use of flash steam routed to heat exchangers or the deaerator to preheat boiler makeup water or support the deaeration process, respectively. In addition, better level control technology at the boiler side eliminates energy losses resulting from unnecessary blowdown to prevent carryover conditions.

Secondly, in cement production, material level measurement encountered another difficulty is strong dust interference, especially pneumatic conveying powder silo, dust flying when feeding, low visibility, laser level meter and high energy ultrasonic level meter can not be measured, although radar level meter at this time can receive part of the surface echo. But the echo signal was also weakened. In addition, due to the uneven surface of the radar echo is refracted, will also lead to the existence of radar echo; In addition, there are some conditions from the bottom to the bin inflation, so that the material surface loose, material level measurement is more difficult.

The installation of the liquid level gauge should be away from the inlet, outlet, eddy current or protrusions on the inner wall to avoid the interference of electromagnetic waves and affect the measurement. When installing the guided wave radar, make sure that the diameter of the short pipe at the flange connection is greater than the height of the short pipe, otherwise the cable will contact the short pipe wall due to shaking, and the liquid level cannot be measured accurately. How to choose a model, in the final analysis, you still need to understand your own working conditions and the characteristics of different instruments, and judge whether the two match, so that you can get twice the result with half the effort.Want to know about ultrasonic flow meter advantages and disadvantages, click here.
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.
