Level gauge supplier factory 2022? 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.

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.
Measurement accuracy, the accuracy of ordinary radar is generally ±10mm, and the accuracy of precision radar is ±3mm. Selection according to the actual needs of production. Range, according to actual needs, choose the antenna size. Note that the actual range is reduced in complex environments. Antenna type and antenna size, the larger the antenna size, the larger the measured range and the stronger the anti-interference ability. The antenna types of radar level gauge are rod type, bell mouth type, paraboloid and so on.
The electromagnetic wave emitted during measurement can pass through the vacuum, no transmission medium is required, and the anti-interference ability is strong, and it is not affected by temperature, wind, water vapor, water mist, rain, etc. It can be used for liquid level measurement of almost all liquids, and can be continuously measured on-line unattended. Large measurement range, high precision, mature technology and stable performance.

There is AC interference and the voltage is high. For example, for the radar level meter used in the production line, the power supply requirement is 24VDC (typical value), but in the on-site measurement, it is found that the power supply is displayed as 27.2V, which is significantly higher than 24VDC, resulting in a large measurement result and even a radar level meter. crash phenomenon. The installation position of the radar level meter is incorrect, which leads to deviations in the measurement. For example, the accumulation of aggregates in the transfer bin is a “mountain”-shaped cone, but only one radar level meter is installed near the discharge port of the return belt. , the installation position is too close to the discharge opening of the return belt, and at the same time, it is too far from the discharge opening of the feeding belt on both sides. Just below the radar level meter is the drop point of the return belt. If the distance is too close, the aggregate in the falling process will interfere with the radar level meter and form false reflections.
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.
