The invention relates to a system and method for testing a turbulence sensor, and belongs to the technical field of turbulence detection. The system comprises an air pressure water tank, a water pump,an air compressor, a flowmeter, a water spraying column barrel and a water accumulation tank. The air pressure water tank is divided into a closed part and an open part. The water pump is arranged inthe open part and is connected with the closed part through a water pumping valve. The air compressor and the flowmeter are both connected with the closed part, another end of the flowmeter is connected with a bottom of the water spraying column barrel, a top of the water spraying column barrel is connected with the water accumulation tank, the water accumulation tank is divided into a main watertank and an auxiliary water tank which are concentrically arranged, the main water tank is connected with the open part through a water conveying pipeline, and the auxiliary water tank is provided with a fixing support for fixing a to-be-tested turbulence sensor. The testing system can effectively carry out turbulence experiments of the turbulence sensor and measure the magnitude of shearing force borne by the sensor at different water flow velocities, and therefore a powerful scheme and data support is provided for experiments of the sensor in an external field marine environment.
