古大雷达液位计在罐区的应用现状

Application Status of Large Radar Level Gauge in Tank Farm

随着仪表技术的发展,罐区液面测量逐渐由机械式测量向智能化仪表发展,在罐区使用最普遍的智能化仪表是雷达液位计,利用回波测距原理进行测量液位。其中,古大雷达液位计是国内技术比较领先的液位计,其工作方式是经变送器天线发射出脉冲微波信号,迅速在空间里传播,传播过程中遇到被测介质表面,其部分脉冲微波信号被反射回来,被雷达变送器天线所接收。利用发射的脉冲微波与接收脉冲微波的时间间隔与变送器天线到被测介质表面的距离成正比来进行液面测量,是国内最早使用26GHZ脉冲微波测量的物位计。

With the development of instrumentation technology,the liquid level measurement in the tank area gradually develops from the mechanical measurement to the intelligent instrument.The most commonly used intelligent instrument in the tank farm area is the radar liquid level meter.The measuring liquid Bit.Among them,the ancient radar level gauge is the leading domestic technology level gauge,the work is transmitted by the transmitter antenna pulse microwave signal,the rapid spread in space,the media encountered in the process of measuring the surface of the media,its Some of the pulsed microwave signals are reflected back and received by the radar transmitter antenna.The use of pulse microwave transmitter and receiver pulse microwave time interval and the transmitter antenna to the surface of the measured medium is proportional to the liquid level measurement is the earliest use of26GHZ pulse microwave measurement level gauge.
