PHYSICAL AMOUNT MEASUREMENT APPARATUS
Document Type and Number:
Japanese Patent JP2023092040
Kind Code:
A
Abstract:
To provide a physical amount measurement apparatus which can increase the design flexibility.SOLUTION: A physical amount measurement apparatus 1 comprises: a buoyancy module 2 which is configured such that buoyancy acts thereon in a well; a sensor module 5 which detects a physical amount of measurement object fluid; a sampling module 4 which can collect the measurement object fluid; a storage container 3 which stores a data logger 6 that receives and records a detection signal detected by the sensor module 5; a weight 7 which is configured to dissolve at a desired position in the well; and a connection member 8 which connects the buoyancy module 2, the storage container 3 and the weight 7 with each other. The storage container 3 is configured to sink due to the weight of the weight 7 to the desired position in the well and float in the well due to the buoyancy acting on the buoyancy module 2 when the weight 7 dissolves.SELECTED DRAWING: Figure 2
