发明名称 MEASURING DEVICE AND MEASUREMENT METHOD USING SAME
摘要 PROBLEM TO BE SOLVED: To provide a measuring device and a measurement method using this which enable measurement of volume or the like of a sample, such using aggregate, and is also capable of the measurement of an air amount within the sample, such as fresh concrete, using a simple operation. SOLUTION: The measuring device comprises a cylindrical vessel 2 which the sample and water of a predetermined amount are thrown in, respectively, and a measuring instrument 3 mounting on an upper part of the cylindrical vessel 2. The measuring instrument 3 consists of an indicator needle which indicates a measured value, a float 38 which floats on the water over the sample and measures a water level, and a transmission mechanism which converts a vertical movement of the float 38 into a movement of the indicator needle. The amount of air is measured by throwing in, in the cylindrical vessel 2, a predetermined amount of the sample and water, respectively, the measuring instrument 3 is mounted on the upper part of the cylindrical vessel 2, then the measured value is read out by the indicator needle.
