注意事项:测量范围从波束触及罐低的那一点开始计算,但在特殊情况下,若罐低为凹型或锥形,当物位低于此点时无法进行测量。 Note for radar level gauge : the measurement range is calculated from the point where the beam touches the tank low, but in special cases, if the tank low is concave or conical, the measurement cannot be performed when the level is below this point. If the medium has a low dielectric constant, when the tank is at a low liquid level, the tank can be seen low. At this time, in order to ensure the measurement accuracy, it is recommended to set the zero point at a low height of C. It is theoretically possible to measure the position of the antenna tip, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100 mm from the antenna tip. For overflow protection, a safety distance can be defined to be attached to the dead zone. The minimum measurement range is related to the antenna. Depending on the concentration, the foam can both absorb microwaves and reflect them, but it can be measured under certain conditions.

,我们已经使伺服技术的性能、精确性和可靠性达到完美,我们看到了雷达测量的更大潜力。 Although in radar level gauges , we have perfected the performance, accuracy and reliability of servo technology, we see greater potential for radar measurement. We are developing new software to increase the reliability of the equipment, which will also expand its application in more occasions. "Our goal is to achieve the optimal application of storage tank volume measurement," said the radar level gauge. "Even in the future, for radar technology, we will no longer see the" universal "device, the application process, In other words, the mechanical and physical environment will determine which measurement method is best. Radar level gauges explain that undirected microwave (radar) and guided microwave (TDR) can meet these needs well. In addition to pure technological developments, attention will also be paid to equipment handling and operation. The radar level gauge's professional application antenna Including parabolic antenna designed for liquid with poor reflection performance. The temperature range of this parabolic antenna is: -40 ℃ ~ + 200 ℃; the pressure range is from vacuum to 3bar.

Radar level gauge installation: The recommended distance is from the wall to the outer wall of the short tube; the tank diameter is 1/6 of the tank diameter, and the minimum distance is 200mm; it cannot be installed above the inlet; if the distance between the meter and the tank wall cannot be maintained , The medium on the tank wall will stick to cause false echoes, and false echo storage should be performed when debugging the instrument. Radar level gauges for solid and liquid media are suitable for a variety of complex measurements, such as small dielectric constant media, large temperature and pressure changes, corrosive conditions, fly ash and other media, and volatile corrosive liquid media.
