Premium flow meter provider: In daily life and industrial production and operation, often need to understand the liquid level in the container. Part of the situation is due to the tank is too large, people are not convenient to enter and tanks and other container materials are not permeable and other factors, this time the need for relevant instrumentation to help, then you know, liquid level measurement are where the instrumentation? It is reported that the instrumentation to measure the liquid level is called liquid level meter. Liquid level meter for the level of a kind of instrumentation. Types of liquid level meters are tuning fork vibration type, magnetic floating type, pressure type, ultrasonic, sonar wave, magnetic flap, radar and so on. See extra information at flow meter manufacturer.
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.
An important part of steam generation is the quality of the steam generated. Maintaining water quality in the boiler within design parameters ensures the highest quality steam possible while minimizing blowdown of the boiler, both of which improve energy and resource management. Continuous or manual blowdown of the boiler minimizes scale accumulation and corrosion resulting from impurities in the water. The blowdown provides a means of accommodating liquid and impurities from the boiler, with the latter facilitating energy recovery through the use of flash steam.
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.

In the measurement circuit of the radar level gauge, when there is additional DC current and voltage, it is DC interference. In severe cases, the measuring instrument will not work properly. The sources of DC interference are as follows: AC interference can be divided into line-to-line interference and ground interference. Inter-line interference refers to the AC voltage between the output ends of the radar level gauge (compensation line) under external influence. This interference is also known as lateral, common mode or common mode interference. Generally speaking, the line-to-line interference voltage can reach several millivolts or even tens of millivolts.
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.
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.
For the ultrasonic instrument that continuously measures the liquid level, when the temperature of the liquid to be measured changes greatly, the change of the propagation speed of the sound wave should be compensated. The connecting cable between the detector and the converter should take anti-electromagnetic interference measures. The structure of the ultrasonic level sensor should be determined according to the process requirements and on-site working conditions.
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.
