| 摘要 | PURPOSE:To inject an extremely small quantity of flow accurately by controlling the pressure difference from an injection liquid source as the condition of liquid dripping regardless of the pressure of liquid to be injected. CONSTITUTION:A drop pipe 12 communicating with the injection liquid source 5, a detector 21 which detects a drop from the drop pipe 12, and an injection pipe 20 which injects a detected and metered injection liquid into the liquid 1 to be injected are provided. The pressure difference between the injection liquid source 5 and injected liquid 1 is held constant regardless of the pressure of the injected liquid 1 so that the injection liquid flowing out of the drop pipe 12 forms liquid drops all the time, and the number of drops is counted to calculates the quantity of injection liquid. | ||||||
