Introduction
Principle & Structure
The radar level meter antenna emits a very short pulse with very low energy. This pulse propagates in space at the speed of light. When it encounters the surface of the measured medium, part of its energy is reflected back and received by the same antenna. The time interval between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium. The radar level meter adopts a special correlation demodulation technology, which can accurately identify the time interval between the transmitted pulse and the received pulse, so as to further calculate the distance from the antenna to the surface of the measured medium.
Features
● The beam angle is small and the energy is concentrated, which has more flexibility for the selection of the radar installation position. It has stronger anti-interference ability, which greatly improves the measurement accuracy and stability.
● The antenna size is small, which is convenient for radar installation on site, and has better adaptability to the measurement of small tanks and special tanks.
application
Suitable for measuring solid particles, slurries, water, oil flow medium corrosive liquids, slurries: for example: process reaction storage tanks, acid-base storage tanks, solid storage tanks, small oil storage tanks and other storage containers or process containers, process conditions Complex liquids and solids: such as crude oil, light oil storage tanks, volatile liquid storage tanks, liquid reaction tanks, lime, coal, etc. Mainly used in petroleum, chemical, metallurgy, food, cement, coal and other industries
The measurement blind area is small, which maximizes the measurement range of the radar.
The wavelength is shorter, and the measurement effect is better for the level of powder, particles, etc.
Transmit pulse signal, radar level meter transmit power is extremely low, can be installed in various metal and non-metal containers, no harm to human body and environment.
It adopts advanced microprocessor and unique echo processing technology and algorithm.
It can be applied to various complex working conditions.
