Premium radar level sensor supplier? 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.

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.

So what can be done about these difficulties? Under the condition of strong dust, on the one hand, the radar with high transmitting energy can be selected, on the other hand, the measurement software with continuous measurement algorithm of wave-loss waiting can be selected. When the radar encounters strong dust, it will not misjudge the measurement result even if the radar loses wave for a short time. After entering the state of continuous measurement algorithm, if the reflection wave of real material surface can be recognized within the set waiting time, the correct measurement value of material surface can be obtained. In the past, only a few foreign radars have this function. At present, there are also domestic radars with this function, and the practical application effect is very good.

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 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.

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.
