为了适应高流速时在水文缆道上测深的要求,我们经多年研究设计试制了一种用微处理机控制和进行信息处理的CJ83型超声波测深仪。该仪器与一般的数字显示式测深仪有着完全不同的工作方式,能在很强的水下噪声干扰环境中施测水深。1983年以来,我们使用该仪器多次在流速高达5～6米/秒的河道中进行了测深,最高在6.07米/秒流速时测到了水深,取得了大量实测对比资料。现将情况介绍于下:
In order to meet the requirements of sounding on the hydrological cableway at high flow rates, we have tried and tested a type CJ83 ultrasonic depth sounder controlled by microprocessors and performing information processing for many years. The instrument and the general digital display depth sounder has a completely different way of working, in a strong underwater noise in the environment of water depth. Since 1983, we have used this instrument to conduct several times of sounding in rivers with a velocity of 5 ~ 6 m / s. The water depth has been measured up to 6.07 m / s, and a large amount of measured data has been obtained. Now the situation introduced in the next:
