Top level measurement instruments 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. Read additional information on level measuring instruments.
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.
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.
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.
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.

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.
Mechanical interference, the so-called mechanical interference, means that some components inside the radar level sensor will also vibrate due to the large-scale vibration or impact of the external machine, and even undergo displacement and deformation, which may also cause the pointer of the instrument head to loosen and cause measurement. error. In this case, we usually use spacers, shock springs, etc. to cushion the shock.
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.
