Premium Radar level measurement wholesale manufacturer: When the cover above the closed metal cover is opened, the false signal disappears, the overall noise line decreases, and the echo curve decreases. After analysis, it is determined that the closed metal cover is the main cause of false signals, the radar level meter antenna is made of plastic, and the radar waves emitted by the antenna leak into the external environment. The closed metal shield is used to cover the instrument, and the leaked radar wave signal is received by the antenna after several reflections inside the shield, generating a false level. Therefore, the metal shield was modified to a ring-shaped non-sealed shield at a later stage, and the radar level meter jump was significantly reduced.

Robustness in Challenging Environments- Industrial environments can be unpredictable with fluctuations in temperature, pressure and the composition of gases and vapors within vessels. Radar level sensors are specifically designed to perform under such conditions ensuring consistent accuracy regardless of external factors. Ability to Handle Different Product Characteristics- Regardless of changes in density, conductivity or dielectric constant radar level sensors maintain their accuracy. This versatility allows them to effectively measure a range of substances, from liquids to powdery solids.
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.
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.
The performance of any level technology relative to instrument induced errors, calibration nuances, and vulnerabilities to process dynamics can have an immediate and adverse impact on fuel consumption. Seamless response to changes in demand and reducing maintenance associated with the instrumentation or damage to hardware are residual benefits that have their own financial ramifications; these aspects should also be considered when implementing any technology. In addition to the “open” or deaerating feedwater heater, the more common shell and tube heat exchangers/condensers can be found in larger scale steam generation cycles where their costs are offset by gains in thermal efficiency. The effectiveness of a shell and tube heat exchanger in transferring energy is contingent, barring hardware anomalies, on accurate level control.
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.

The interference comes not only from the outside, but also from the inside of the radar level gauge, such as interference caused by wires, inductance and capacitance between the power transformer and electronic components. In addition, the internal components can also generate noise interference. Today, most radar level gauges have also begun to be improved, using high-frequency microwave technology, which greatly improves the performance of the level gauge and reduces interference.
For the continuous measurement of corrosive, high viscosity, flammable and toxic liquids, liquid-liquid interface and solid-liquid interface that are difficult to measure by ordinary liquid level meter , ultrasonic level meter should be selected, but should not be used in occasions with large liquid level fluctuations . Ultrasonic level meter are suitable for measuring media that can fully reflect and transmit sound waves, but should not be used in vacuum. The ultrasonic flow meter should not be used in process equipment where internal obstacles affect the propagation of sound waves.
The influence of dust accumulation on the transmitter head of the radar level meter, due to the large amount of dust in the working condition of the radar level meter, the dust is easy to adhere, and affected by the ambient temperature, the dust is wet and easy to agglomerate, and the dielectric constant will become larger and adhered The transmitter head and the wall of the bell mouth of the radar level meter affect the accuracy and stability of the radar measurement.
