The utility model relates to a device for measuring the flow of a cryogenic medium by adopting a throttling device, which comprises a process pipeline in which a liquid cryogenic medium flows; the throttling device is arranged on the process pipeline; the first pipeline is connected with an output port of the throttling device; the root valve is arranged on the first pipeline and is close to the throttling device; the second pipeline is connected to the first pipeline and extends upwards; and the differential pressure transmitter is connected to the end part of the second pipeline and is positioned above the throttling device. According to the utility model, the differential pressure transmitter is arranged above the throttling device to measure the cryogenic medium in a complete gasification state, so that the fluctuation, error and failure of flow measurement of the liquid cryogenic medium are eliminated on the premise of not replacing the measurement mode; the device disclosed by the utility model is simpl
