Radar level sensor provider China: Radar level meter adopts non-contact measurement, and has the advantages of high measurement accuracy, not affected by process conditions, easy to install and easy to maintain, so it is widely used in offshore oil platforms in recent years. Today, we would like to take you through several actual cases in offshore oil platform to understand the reasons and solutions of the radar level meter’s measurement value jumping. The first case was an oil field where the radar level meter in the left crude tank jumped to full scale several times during production. A sealed metal cover was used to cover the main body of the sensor, and during the test, it was found by connecting the radar level transmitter that the closed metal cover would result in more false signals throughout the measurement range, and the overall noise line would rise.

Remote Accessibility – Industrial processes often span across intricate and complex facilities. IIoT radar sensors grant operators and engineers the ability to access data remotely eliminating the need for physical proximity to the sensor. This functionality simplifies troubleshooting, reduces response times to irregularities and minimizes periods of inactivity. Predictive Maintenance – One of the advantages of IIoT-enabled radar sensors is their capability to anticipate maintenance requirements. By analyzing data patterns these sensors can forecast when maintenance or calibration will be necessary, allowing for intervention before problems escalate. This predictive maintenance feature significantly improves equipment reliability and lifespan.

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.

Measuring principle of radar water level meter: The radar level gauge adopts the working mode of transmitting-reflecting-receiving. The electromagnetic wave emitted by the antenna is reflected by the surface of the measured object and then received by the antenna. After measuring the distance from the water surface to the radar antenna, the elevation of the water surface can be calculated according to the elevation of the radar antenna. The radar water level meter adopts pulse wave technology with low power consumption. It can be powered by two-wire 24 VDC, 485 interface output, or can be directly powered by 12 VDC, SDI-12 interface output, with high accuracy and wider application range.

Level Measurement Solutions for Deaerators: With proper level control and instrumentation, every part of the steam generation cycle can be managed for optimal efficiency. Deaerator Functions: The deaerator serves as an “open” type heat exchanger with its primary function being the removal of oxygen and other corrosive gases from the boiler feedwater. This is accomplished using steam, which can give up about 970 Btu per pound, to support the deaeration process as well as preheat boiler feedwater.

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.

Humidity interference, when the humidity increases, it will cause the insulator resistance to decrease, the dielectric constant to increase, the skeleton to be fluffy, and the resistance to increase, resulting in an increase in leakage current and changes in capacitance and inductance. Also, it softens the colloid and reduces measurement accuracy. Chemical interference, chemical interference usually refers to some corrosive gases, such as acids and alkalis. The long-term action of these gases will not only damage the instrument and internal components, but also conduct electricity with the metal, affecting the normal operation of the radar level transmitter.

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.

Product features: The gas display is red and the liquid display is green, the luminous display is clear, the observation is large, and the visual distance is long. The liquid level sensor can be clearly displayed by red and green light column, which is suitable for application in dark places and more eye-catching at night. The body is made of stainless steel, the level meter display device does not contact the medium in the container, and there is no leakage. Suitable for first, second and third class containers, suitable for containers containing flammable, toxic and corrosive media.
