Level indicators supplier factory by Kaidi86? Thermal interference. During the operation of the thermal power plant, its thermal equipment will generate a lot of heat, causing changes in the surrounding instruments and ambient temperature. This is what we call thermal interference. These disturbances can affect the components of the magnetrol radar level gauge and further create problems such as inaccurate measurements. Light interference, light interference mainly exists in semiconductor components. Many components used to control instruments are made of semiconductor materials whose conductivity changes under the influence of light. This will affect the normal use of the radar level gauge.

Any appreciable gain in boiler feedwater achieved through the process reduces the amount of energy (fuel) required at the boiler— in fact, every 10.8°F (6°C) rise in boiler feedwater amounts to a one percent savings in fuel cost. Inadequate level controls can inhibit the deaeration process (level too high) or reduce/shutdown feedwater flow to the boiler (level too low). The former affects hardware longevity and efficiency, while the latter risks production losses and possible damage to pumps.
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.
Rod antenna: generally used in strong corrosive environments, with weak anti-interference ability and small range; Flare antenna: stronger anti-interference ability, suitable for more complex environments. The larger the bell mouth, the more concentrated the energy, and the larger the measuring range; Parabolic antenna: the focusing effect is stronger than that of the bell mouth, the anti-interference ability is the strongest, and the range is the largest.
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 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.
