Radar level sensor supplier by kaidi86.com? 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.

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.

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.

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.

Ground interference refers to one of the two output ends of the radar level gauge (or compensation line), and its AC voltage to the ground is called the ground interference voltage. This disturbance is also known as longitudinal, in-line mode or in-line state disturbance. Generally speaking, the interference voltage to ground can reach several volts or even more than 100 volts. The above is the interference of the radar level gauge we discussed. When we install or use the radar level gauge, we can also determine whether your use environment will cause these interferences to the level gauge according to the above situation. If these conditions exist, anti-interference measures must be taken to ensure that the level gauge can serve you better.

Product features: Large display range, wide range of use, suitable for low temperature, medium temperature, high pressure occasions. It can be matched with remote transmitter output 4-20MADC standard signal to realize remote display of liquid level guage. It can also be matched with liquid level switch to realize liquid level control. Generally speaking, the material level feedback is inaccurate and untimely, which is very prone to explosion events, and there is a greater safety risk. Therefore, the requirements for the radar level meter are very high, but the radar level meter often has abnormal material level jumps or falls, or even crashes, resulting in large errors in material level measurement, which brings trouble to production and sales.
