Level indicator for tank supplier factory China? 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. Discover more information at level indicator for tank.
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.
Application conditions, application conditions generally include calm liquid level, slightly fluctuating surface, turbulent surface, with stirring, with foam and so on. The more complex the conditions, the more interference echoes, and the smaller the actual measured range. In a complex environment, a precision radar with strong ability to deal with interference echoes or an antenna with a larger size should be selected.
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.
Under many operating conditions, ultrasonic level meter and radar level meter are commonly used. Some users are very entangled in the choice of these two level meter and do not know how to choose. Today, let’s talk about the principles and selection principles of these two types of level meter . Principle and selection principle of ultrasonic level meter. Working principle: The ultrasonic pulse probe emits a beam of ultrasonic pulses to the measured medium, and the sound wave is reflected by the liquid surface. The distance between the liquid levels is measured by measuring the time difference between the emission and reflection of the sound waves. Since the ultrasonic level gauge is not a liquid, it can be used to measure corrosive, non-volatile and non-foaming places.
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.
