Top rated level indicator for tank manufacturer? 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.

For more accurate measurement in deaerators, magnetrol guided wave radar (GWR) is a preferred option. Since its performance and accuracy are not contingent on the specific gravity and/or inference, it can provide reliable measurements in all situations, including the difficult and turbulent process conditions of deaerators and feedwater heaters. In addition, GWR does not require external inputs or calibration to achieve specified performance. This effectively eliminates the introduction of errors during the calibration process or from external sources, i.e., pressure and temperature. With this high level of accuracy, operators can trust that their deaerators will be well controlled.
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.
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.

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.
When the distance between the liquid level of the measured medium and the electromagnetic wave transmitter is less than 4m, the guided wave radar is selected. If the distance between the liquid level of the measured medium and the electromagnetic wave transmitter is greater than 4m and less than 35m, select the guided wave radar with the guided wave cable. When the distance between the liquid level of the measuring medium and the electromagnetic wave transmitter is greater than 35m, or when the liquid level of the measuring medium is high temperature, high viscosity or solid liquid level, the air-shooting radar should be selected.
