FLOW RATE MEASURING TOOL FOR CHEMICAL DEVICE

PURPOSE:To obtain a flow rate measuring tool which can perform measurement and adjustment of a flow rate within a pipe by a chemical device etc. in a short time, efficiently, and accurately under an improved working environment by a small number of workers. CONSTITUTION:A title item consists of a tubular cylinder container 1a where a graduation 1b is marked on a pipe wall and at least an outer wall 1d near an upper-edge opening 1c is adhered to an inner wall or a tip part of a pipe whose flow rate is to be measured. It is recommended that the cylinder container 1a is made of glass, plastic, etc., and a grip 1e is mounted to the cylinder container 1a. By inserting a flow rate measuring tool into the upper-edge opening of the pipe whose flow rate is to be measured, a liquid which flows into the pipe whose flow rate is to be measured can be sampled without any leakage, thus achieving an accurate measurement of flow rate simply by operation from an upper side of the pipe whose flow rate is to be measured and at the same time enabling a flow-rate adjusting operation to be performed from an upper side so that these operations can be performed in a short time, efficiently, and accurately under an improved environment.
