Radar level sensor manufacturer China: 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.

Unveiling the Benefits – The popularity of radar level measurement has significantly increased due to its range of advantages. Let’s explore these benefits, which have solidified radar’s position as the choice in industries- Accurate and Non-Contact Measurement- One of the key attractions of radar level measurement is its non-contact approach. Unlike methods that require interaction between sensors and materials radar sensors use electromagnetic waves to measure levels and capture reflected signals. This contactless method minimizes the sensor tear, leading to greater lifespans and reduced maintenance costs.
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.
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.

See extra information at https://www.kaidi86.com/. The Magnetic Level Gauge all use vacuum tube technology, with a lifespan of 3-5 years, and protection grade is up to IP68, not easy to fade.
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.
