特徴とする請求項第１項に記載の流速制御装置。[Claims for Utility Model Registration] 1. A flow rate control device that controls the flow rate of fluid supplied using a pump and flowing into a predetermined pipe diameter section, which temporarily retains the fluid between the pump and the pipe section to control the flow rate. A buffer container for buffering, a pressure detection means for detecting the pressure inside the buffer container, and a control section for controlling the power supply of the pump on and off based on the signal of the pressure detection means are provided, and the pressure inside the buffer container is set to a predetermined value or more. 1. A flow rate control device that turns off the pump power when the buffer temperature reaches 100 mm and causes the fluid to flow using the pressure inside the buffer container. 2. The flow rate control device according to claim 1, wherein the volume of the buffer container is variable.
