Excellent level measuring instruments supplier factory: Radar level measurement represents a shift in the field of instrumentation. This state-of-the-art technology utilizes radar waves to determine levels of liquids or solids, in vessels. Unlike methods that require contact radar operates non invasively by emitting microwaves and carefully analyzing the reflected signals. The key radar level measurement principle here is time of flight measurement- accurately measuring the time it takes for a radar pulse to travel from a transmitter, bounce off the surface of the material and return to a receiver. This temporal data is then converted into an accurate level reading. See even more information on level measurement instrument.

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.

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.

If the radar level meter is unreasonably selected, the interference echo cannot be handled well, and the reliability of the instrument will be reduced. Therefore, the following factors should be considered when selecting a radar level meter: Conductivity and dielectric constant of the measured medium. The measured medium is a conductive liquid or a liquid with a dielectric constant above 4. Generally, a common radar is selected. Liquids with small dielectric constants (dielectric constants below 2) and some conductive solids often use precision radars or guided wave radars due to the large amount of interference echoes.

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.

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.

As one of the most professional magnetic level indicators manufacturers in China,Guangdong Kaidi Energy Technology Co., Ltd. provides customized solutions for a range of industrial automation process applications,such as mechanical float level indicator.We specialized in radar level gauge, fork type level switch,etc. These were implemented successfully, and KAIDI magnetic level gauge manufacturers products,such as radar level meter, magnetic level indicators, can be used in many different industries such as food & beverage, water, energy, pharmaceutical etc. Our Radar Level Meter has a range of up to 150 meters, frequency up to 120GHz and an accuracy of ±1mm, which can cope with various complex measurement conditions.

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 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.
