是一种微波物位计，它是微波(雷达)定位技术的一种运用。 Intelligent radar level gauge is a microwave level gauge, which is an application of microwave (radar) positioning technology. It transmits energy waves through a device that can transmit energy waves (generally pulse signals). The energy waves are transmitted in the waveguide. The energy waves are reflected by obstacles. The reflected energy waves are transmitted by the waveguide to the receiving device. The receiving device receives the reflected signal. The change in level is determined according to the time difference of the measured energy wave motion process. Microwave signal is processed by the electronic device, into electrical signals associated with the final position thereof.
Due to the use of advanced microprocessor and unique EchoDiscovery echo processing technology, the radar level gauge can be applied to a variety of complex working conditions. The "false echo learning" function enables the meter to correctly confirm the true echo and obtain accurate measurement results under the conditions of multiple false echoes. A variety of process connection methods and antenna types make CCRD800 series radar level gauges suitable for a variety of complex working conditions and applications. Such as: measurement of high temperature, high pressure and small dielectric constant medium. Using pulse working mode, the radar level meter's transmitting power is extremely low. The maximum pulse energy of the general pulse energy wave is about 1mW (average power is about 1μW). It can be installed in various metal and non-metallic containers. No harm.

的介绍，目前来说，对于智能雷达物位计已经不陌生了，其测量原理如下:发射能量很低的极短的微波脉冲通过天线系统发射并接收。 In fact, according to the previous introduction of the smart radar level meter , at present, it is no stranger to the smart radar level meter. The measurement principle is as follows: extremely short microwave pulses with very low transmission energy are transmitted and received through the antenna system. Radar waves travel at the speed of light. The running time can be converted into a level signal by electronic components. A special time extension method ensures stable and accurate measurements in a very short time.
Application medium of smart radar level meter:
1. It adopts the measurement method of microwave pulse, and can work normally in the range of industrial frequency band. The beam energy is low, and it can be installed in various metal, non-metal containers or pipes without harming human body and the environment. 2. The intelligent radar level gauge is suitable for non-contact continuous measurement of the level of liquids, slurries and particulate materials, and where the temperature and pressure change are large, and there are inert gases and volatilities.
Knowing the basic knowledge of the above intelligent radar level gauge is very useful for its practical operation ...
