Zusammenfassung:	A ray transceiving system of an underwater flowmeter includes a flowmeter body. A fluid metering channel, a transmitting window, and a probing window are arranged on the flowmeter body in a penetrating mode. The transmitting window and the probing window are respectively in communication with the fluid metering channel, and each of the transmitting window and the probing window is provided with a titanium alloy isolation seat and a beryllium pad. Titanium alloy which is relatively easy to process and form is used to seal the fluid metering channel, the titanium alloy and the beryllium pad are combined to bear pressure, and the beryllium pad is used to reduce absorption of gamma rays. A deduction metering method of the underwater flowmeter partially deducts the gamma count rate distortion caused by the Compton scattering effect in the algorithm, and calculates the content of each phase in a three-phase mixed flow to improve the metering accuracy of the three-phase content of oil, gas, and water.
