The lifting cap directs the vapour to flow horizontally into the liquid, thus providing better mixing than is possible in sieve trays.
被掀起的泡罩将蒸气水平引入液层，从而提供比筛板塔盘更佳的汽液混合效果。
Connected with flow transducer outputting impulsive signal, it can measure the instant flow, accumulative flow, mass flow of the liquid, the gas or the vapour.
可以与多种脉冲信号输出的流量变送器配套使用，精确地测量液体、气体和蒸汽等流体介质的瞬时流量、累积流量和质量流量。
It can measure the flow rate of all sorts of vapours, and use on line compensation of pressure and temperature to measure vapour.
可测量各种气体的流量，测量蒸汽可用压力、温度在线补偿。
The Model AS-2 is designed to check velocity and direction of air flow continuously with a smoke tube (No. 301) which reacts with vapour in the air and generates white smoke.
该型号AS - 2的目的是检查速度和方向的空气流动的烟管（301）的反应与空气中的蒸汽并产生白烟不断。
