The invention relates to an aircraft fuel liquid level fluidic sensor test system which comprises a test board. A control system and a fuel oil test system are mounted in the body of the test board. The fuel oil test system comprises an oil collecting tank and a pneumatic part, and a fluidic nozzle connector, a receiving nozzle connector and a cutting off nozzle connector are arranged on the inner side wall of the oil collecting tank. A turbine flow sensor and a fluidic nozzle pressure transmitter are arranged on an inlet pipeline of the fluidic nozzle connector, a receiving nozzle pressure transmitter is arranged on an outlet pipeline of the receiving nozzle connector, the turbine flow sensor is connected with a PLC impulse input interface of a control system, the fluidic nozzle pressure transmitter and the receiving nozzle pressure transmitter are both connected with the PLC of the control system, and a cutting off nozzle solenoid valve connected with the PLC of the control system is arranged on the inlet pipeline of the cutting off nozzle connector. The aircraft fuel liquid level fluidic sensor test system can be connected to a liquid level fluidic sensor with two interfaces or three interfaces, and carry out performance test of pressure, flow and the like on the liquid level fluidic sensor with the two interfaces or the three interfaces.
