加长 U 形管是根据连通器的原理制作的,它测量的数据精度比较高,设备简单,操作方便,在石油大容器检定方面,能解决标定水平与测量倾斜度的问题。一、检定水泥油罐方面目前不但各石油炼厂修建了一些万吨以上的大水泥油罐,各县各公社也修建了些千吨以下的水泥油罐(俗称土油罐),随着农业要全面实行机械化。所以测量水泥油罐的容量工作日益广泛。根据上海石油采购供应站、上海炼油厂、上海市计量局共同
The longer U-shaped tube is made according to the principle of the communicator. The data of the U-shaped tube has higher accuracy, simple equipment and convenient operation. It can solve the problem of calibration level and measurement inclination in the verification of large-scale oil containers. First, the verification of cement tanks Currently not only the construction of some of the oil refinery tons of large cement tanks, counties and communes also built some thousand tons of cement tank (commonly known as soil tank), with agriculture To fully implement mechanization. Therefore, measuring the capacity of cement tanks is increasingly widespread. According to Shanghai Petroleum Procurement Supply Station, Shanghai Refining Factory, Shanghai Bureau of Metrology together
