Best rated flow meter measuring devices factory: In this paper, there are three situations that lead to the radar level meter measurement value jump, respectively, closed metal cover, condensation on the antenna, power supply power supply is insufficient. In fact, the radar level meter measurement value jump belongs to a relatively common problem, leading to the emergence of this problem for a number of reasons, the emergence of problems in a timely manner to find the cause and solve the problem is the most important. Liquid level is the height of the liquid level in a sealed container (pool) or an open container (pool). In addition, liquid level measurement is divided into two categories: continuous measurement and level measurement. Read additional info at flow instrumentation.
Advanced Radar Level Measurement: The constant progress of innovation continues to push the limits of radar level measurement, propelling this technology into areas of capability and pertinence. As industries undergo transformations and integrate the Industrial Internet of Things (IIoT) into their operational processes radar devices have evolved to meet these changing demands. Integration with IIoT- Leading the Way to Industry 4.0 One of the transformative developments in radar level measurement is the seamless integration of Industrial Internet of Things (IIoT) capabilities into radar devices. These radar sensors equipped with IIoT features have become important components in Industry 4.0 initiatives ushering in an era where data driven excellence prevails in operations.
Power supply and output signal, the power supply has 220 V A C, 24 VDC, and the two-wire or four-wire system can be selected according to the needs. Output signal 4 ~ 20 mA DC or digital signal, select the appropriate model according to the needs. The above are all factors that need to be considered when selecting a radar level transmitter. The essence of the details is a serious attitude and a scientific spirit. I hope that every user can choose a suitable radar level meter.
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.
Any appreciable gain in boiler feedwater achieved through the process reduces the amount of energy (fuel) required at the boiler— in fact, every 10.8°F (6°C) rise in boiler feedwater amounts to a one percent savings in fuel cost. Inadequate level controls can inhibit the deaeration process (level too high) or reduce/shutdown feedwater flow to the boiler (level too low). The former affects hardware longevity and efficiency, while the latter risks production losses and possible damage to pumps.
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.

In the measurement circuit of the radar level gauge, when there is additional DC current and voltage, it is DC interference. In severe cases, the measuring instrument will not work properly. The sources of DC interference are as follows: AC interference can be divided into line-to-line interference and ground interference. Inter-line interference refers to the AC voltage between the output ends of the radar level gauge (compensation line) under external influence. This interference is also known as lateral, common mode or common mode interference. Generally speaking, the line-to-line interference voltage can reach several millivolts or even tens of millivolts.
Working principle: Working principle of radar level gauge: UHF electromagnetic waves are transmitted to the liquid level of the container under test through the cable or antenna. When the electromagnetic wave touches the liquid level and is reflected back, the instrument detects the time difference between the initial wave and the echo, thereby calculating the liquid level height. Select guided wave radar or airborne radar according to the dielectric constant and measurement length of the measured medium.
