Radar level measurement wholesale manufacturer today: The second case is that, in order to ensure the fluidity of crude oil, offshore oil platforms usually use hot medium oil heating pipes to heat the crude oil to ensure that it is stored within a certain temperature range. As the crude oil in the lower tank contains a small amount of water, some of the bottom water will precipitate out of the bilge water after standing, and the water vapor will evaporate during the continuous heating process. The water vapor condenses on the antenna at the top of the tank to form water droplets, causing a strong false signal at the top. Therefore, false signals are suppressed within 0~0.25m and the suppression line is set to 120dB to avoid false signals caused by water vapor condensation and level jumps at the top. In response to this situation, after on-site analysis and research tests decided to do a good job of pre-dewatering treatment, the water content of the crude oil in the lower tank is controlled at less than 0.5%, the heating temperature of the crude oil tank is controlled so that the crude oil in the tank is lower than 65 ℃, and the instrumentation is covered with thermal insulation materials on the outside, etc. Through the above measures, the phenomenon of level jumping caused by the formation of condensation at the antenna of the radar liquid level meter is eliminated.

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.
Power supply and output signal, the power supply has 220 V A C, 24 VDC, and the two-wire or four-wire system can be selected according to the needs. Output signal 4 ~ 20 mA DC or digital signal, select the appropriate model according to the needs. The above are all factors that need to be considered when selecting a radar level transmitter. The essence of the details is a serious attitude and a scientific spirit. I hope that every user can choose a suitable radar level meter.
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.
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.

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.
Under many operating conditions, ultrasonic level meter and radar level meter are commonly used. Some users are very entangled in the choice of these two level meter and do not know how to choose. Today, let’s talk about the principles and selection principles of these two types of level meter . Principle and selection principle of ultrasonic level meter. Working principle: The ultrasonic pulse probe emits a beam of ultrasonic pulses to the measured medium, and the sound wave is reflected by the liquid surface. The distance between the liquid levels is measured by measuring the time difference between the emission and reflection of the sound waves. Since the ultrasonic level gauge is not a liquid, it can be used to measure corrosive, non-volatile and non-foaming places.
