The invention discloses a digital full functional water nozzle test system, which comprises a circulating energy station providing power for a test, a moisture console used for realizing moisture distribution, throttling and counting and a field simulation nozzle water content distribution test bed. The three parts are independent from one another and connected sequentially by pipeline interfaces; all metering devices adopt digital intelligent meters and collect corresponding data which can be input in a computer for processing; the structural styles of the flow distributor of the field simulation nozzle water content distribution test bed are grooves separated by parallel guide plates with the same width; and a transparent glass container below is used as a metering device. By using the system, the flow of a single nozzle and the relation between the spray angle and the flow distribution can be not only measured, also the test of the relation between the spray flow and the flow distribution can be carried out under the condition that a plurality of nozzles mutually interfere; the optimal design of the nozzle can be carried out secondarily, and the digital full functional water nozzle test system has the characteristics of high digitization degree and strong function.
