Level indicators provider today? Working principle: Tube in the liquid level meter has a magnetic float, float design, according to the proportion of medium float magnet steel and container liquid level at the same level, wholesale liquid level gauge in a semiconductor magnetel liquid level gauge sensor LED display scale, and orderly arranged from top to bottom, and LED module corresponding to the magnetic field magnetic sensor, the magnetic semiconductor, triggering the corresponding digital circuit, liquid level above the red LED display, The LED below the liquid level gauge is displayed in green, the red in gas phase, and the green in liquid phase. The red-green junction is the actual liquid level in the container. Discover extra details on level switch.
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.
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.
For radar level gauges, there are many reasons for interference and many sources of interference. We analyze from four aspects: internal, external, AC and DC. Celestial and celestial interference, first of all, what is celestial interference? Celestial objects refer to the sun or other stars, therefore, celestial interference refers to the interference of their electromagnetic waves on the radar level gauge. We are very unfamiliar with Tiandian. The so-called Tiandian is usually understood as the interference of the signal of the magnetrol radar level gauge caused by the ionization of the atmosphere, lightning, or the electromagnetic waves generated by natural phenomena such as volcanoes and earthquakes.
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.
So what are the installation technical requirements for radar water level meters? The installation of the radar water level meter must be vertical to the object to be measured; there should be no obstructions between the measured object and the radar water level meter, otherwise it will affect the reflection of radar waves, that is, affect the measurement accuracy; the center of the radar water level meter is far from the shore of the water body. The distance must be greater than the radius of the transmitting beam, otherwise the measurement accuracy will also be affected; the installation cantilever bracket of the radar water level meter must be firm, and cannot be shaken up and down; in order to protect the radar water level meter, the water level meter can be installed on the cantilever bracket. Iron box, put the radar water level meter probe.
