AI Technical Summary
Technical Problem
Existing hydrogen dispenser inspection devices are uneconomical and inefficient as they require separate setups for dispensers with standard, large, and multiple nozzles, lacking a unified solution for various types of nozzles.
Method used
A single inspection device with multiple receptacles and nozzles, including standard and large-sized, capable of accommodating different nozzle types and reducing the number of flow meters, utilizing a control unit for integrated flow rate calculation.
Benefits of technology
Enables inspection of multiple types of hydrogen dispensers with varying nozzles using a single device, minimizing the need for multiple flow rate measuring devices and ensuring accurate measurement accuracy.

Abstract
To provide an inspection device of a gas dispenser capable of inspecting a plurality of kinds of gas dispensers having different kinds of nozzles by one device, and capable of reducing the number of flow rate measuring instruments for measuring a flow rate of gas.SOLUTION: The inspection device 21 includes a first receptacle 22A and a second receptacle 22B to which the nozzle 4 whose maximum flow amount is set to a first predetermined flow amount (small flow amount) is connected, and a third receptacle 22C to which the nozzle whose maximum flow amount is set to a second predetermined flow amount (large flow amount) is connected. A flow-rate measuring instrument 22A and a flow-rate measuring instrument 22B are respectively provided in a pipeline 24A and a pipeline 24B that respectively connect the first and second receptacles 25A and 25B to the first and second nozzles and. 23B 23A. The third receptacle 22C is connected to the upstream side of the flow-rate measuring instruments 25A and 25B of the pipe lines 24A and 24B via the upstream third pipe line 24C1 and the upstream connection pipe lines 34A and 34C.SELECTED DRAWING: Figure 2
