Excellent Radar level sensor provider: 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.

Effective Echo Management- Pulse radar technology generates echoes at certain time intervals. This feature enables radar sensors to handle echoes and distinguish echoes. A common occurrence in complex process vessels and solid material silos. This capability greatly enhances the accuracy of measurements in situations where traditional methods may struggle. The versatility and dependability of radar level measurement make it suitable for a range of applications. Here are some important areas where radar sensors excel- Process Tanks-In industries, radar level sensors are deployed to monitor levels in process tanks. Whether its chemicals, petroleum products or water treatment facilities radar sensors provide real time data to optimize process control. Storage Tanks- Large scale storage tanks require precise level monitoring to efficiently manage inventory and prevent overfilling or underfilling. Radar sensors are the trusted choice for maintaining inventory balance.
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.
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 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.
In addition, some silos in cement plants are very high, such as homogenizing silos of 50cm. It takes time and energy to board high silos to debug radar, so it is recommended to choose HART handheld operators that can be debugged remotely in the central control room. In the central control room, the range and other basic parameters can be set, and the radar echo waveform can be observed, and the waveform can be used for remote diagnosis and debugging, greatly reducing the on-site work intensity of the staff, to avoid the risk of climbing operation. The smart radar level gauge commonly used at present also has a function similar to “driving recorder”, that is, when the material surface mutation occurs on the scene, it can capture the radar echo waveform at that time, which is very useful for debugging the silo under complex conditions.

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.
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.
