To provide a flow rate measuring system easy in maintenance or correction of its instruments while keeping a heat insulation performance necessary for flow measuring equipment.
The flow rate measuring system is interposed in a low-temperature liquified gas transfer path (2) for transferring low-temperature liquified gas in a liquid status from a supply storage tank (1) of the low-temperature liquified gas into a liquid-receiving reservoir. The system is stored in a cold chamber (7) of a vacuum heat insulation structure composed of a supercooling processing device (4) for performing supercooling processing the low-temperature liquified gas during transfer, a flow meter (5), and a flow control unit (6) together with pipes to be able to open/close. The supercooling processing device (4) is composed of an immersion vessel (8) and a heat-exchanging part (9) housed inside the immersion vessel (8). A branching path (10) branching from the low-temperature liquified gas transfer path (2) in the cold chamber (7) is communicated inside the immersion vessel (8) of the supercooling processing device (4).
