Why can radio frequency level gauges be widely used?Microwave Radar Module sales

　　With the needs of social development, more and more measuring instruments are available. And the most leading position should be the radio frequency position counter.

　　The principle of the radio frequency position counter is to use high frequency radio frequency to accurately measure the specific height of the liquid. The principle is like a bat at night, emitting radio frequency, and an object will reflect the radio frequency back, so as to transmit to the bat there is an obstacle in front of it. Pay attention to avoiding information. The designer uses this principle to measure the height of the water surface. At this time, the water surface is like an obstacle on the path of a bat. The radio frequency is reflected to the instrument, and the distance can be measured to accurately get the height of the water level. From this point of view, the principle is actually Much simpler.

　　Although the principle seems to be so "tall", its advantage is that the operation of the radio frequency position counter is very simple and the reading is very convenient. And its later maintenance is easy to use. It is also very simple to clean, has a long service life, and can perform long-term and high-frequency data measurement after purchase. At the same time, its receiver is very sensitive and can accurately receive the radio frequency reflected from a distance for accurate readings. Therefore, its investment is relatively low.

　　However, the radio frequency position counter is not a perfect instrument, and its work will also be affected by certain specific conditions. Its measurement is prone to blind areas, and the size of the blind area is proportional to the measured distance. The measurement distance is small, the blind area is small, and the measurement distance is large, and the blind area is large. And if the dust concentration in the air is greater during the measurement, the greater the impact on the measurement, because the dust has a great interference to the sound wave, which will seriously affect the radio frequency reception of the radio frequency position counter.

　　In particular, the measurement personnel need to pay attention to that when measuring the height of the liquid level, if there are obstacles under the liquid level, the measured value will be affected, and even the data will be lost during the measurement. Therefore, the surveyor must first check whether there are obstacles under the liquid level before taking the measurement.
