| 摘要 | PURPOSE:To measure a minute flow rate highly accurately over the broad range of the flow rate, by the constitution, wherein the fall of a liquid droplet is detected, and the dropped liquid is made to flow through a thin pipe as a continuous stream. CONSTITUTION:A liquid enters a dropping pipe 2, which is provided at the upper part of a measuring container 1. The liquid receives a specified surface tension at an outer opening part 21 and falls as a specified droplet 3. The droplet is detected by the conduction between electrodes 41 and 42. The liquid reaches a concave part 8 of a flowout pipe part 6, which can be attached and detached freely, through the electrode 42. The liquid becomes a continuous stream, whose flow rate is the same as the flow rate of the liquid entering the dropping pipe 2, through a thin pipe 11 and flows out. Since the droplet 3 is kept in constant conditions all the time, the minute flow rate is measured highly accurately. | ||||||
