Title:
PHYSICAL AMOUNT MEASUREMENT APPARATUS
Document Type and Number:
Japanese Patent JP2023092039
Kind Code:
A
Abstract:
To provide a physical amount measurement apparatus which can suppress a failure of a sensor module and a data logger even when the temperature of fluid in a well is very high.SOLUTION: A physical amount measurement apparatus 1 comprises: a first storage container 2 which includes an outer container 21 and an inner container 22 that is stored in the outer container 21 and has the heat insulation property; a sensor module 5 which is stored in the inner container 22 and detects a physical amount of measurement object fluid; an introduction pipe 3 which is arranged so as to penetrate the outer container 21 and the inner container 22 and introduces the measurement object fluid to the sensor module; a data logger 6 which receives and records a detection signal detected by the sensor module 5; and a first weight 7 which is attached to the outer container 21 and is configured to dissolve at a desired position in the well. The first storage container 2 is configured to sink due to the weight of the first weight 7 to the desired position in the well and float in the well when the first weight 7 dissolves.SELECTED DRAWING: Figure 3
