1.特点以前在生产上使用的超声波流量计,其配管口径均在300mm 以上,所使用的流体温度在0～40℃之间,适用于比较大的口径和较低温度。近年来可望能在原子能设备的高温冷却水流量测量上得到实用,在小口径管路测量上也能达到同一般流量计同样的精确度,并且耐高温。其主要技术规格见表1。 1. Features Used in the production of ultrasonic flowmeter, the pipe diameter are more than 300mm, the fluid temperature used between 0 ~ 40 ℃, suitable for larger diameter and lower temperature. In recent years, it is expected to be practical in the measurement of the high temperature cooling water flow of atomic energy equipment, and the same accuracy as that of the ordinary flowmeter can be achieved in the measurement of small-diameter pipes, and the high temperature resistance is also achieved. The main technical specifications in Table 1.
