The radar level meter emits and receives extremely short microwaves with low power through an antenna system. Radar waves travel at the speed of light. The running time can be converted into level signals through electronic components. A special time extension method can ensure stable and accurate measurements in an extremely short period of time. Even in the presence of false reflections, the latest microprocessing techniques and software can accurately analyze the level echoes. By inputting the container size, the distance value above can be converted into a signal proportional to the level of the object. The instrument can be debugged empty. The application in solid-state measurement can use high-frequency sensors in the K-band. Due to the excellent focusing effect of the signal, the installation materials inside the silo or the adhesion of the silo wall will not affect the measurement.
导波雷达物位计
Guided wave radar level meter
导波雷达物位计的微波脉冲沿着一根缆、棒或包含一根棒的同轴套管运行,接触到被测介质后,微波脉冲被反射回来,并被电子部件接收,并分析计算其运行时间。微处理器识别物位回波,分析计算后将它转换成物位信号给出。由于测量原理简单,可以不带料调整,从而节省了大量调试费用。测量缆或棒可以截短,使之更加适应现场的应用。对于蒸汽不敏感,即使在烟雾、噪音、蒸汽很强烈的情况下
The microwave pulse of the guided wave radar level meter runs along a cable, rod, or coaxial sleeve containing a rod. When it comes into contact with the measured medium, the microwave pulse is reflected back and received by electronic components, and its operating time is analyzed and calculated. The microprocessor recognizes the level echo, analyzes and calculates it, and converts it into a level signal to provide. Due to the simple measurement principle, it can be adjusted without material, thus saving a lot of debugging costs. The measuring cable or rod can be shortened to make it more suitable for on-site applications. Not sensitive to steam, even in conditions of strong smoke, noise, and steam
