〗For accurate ship fuel consumption test and measurement, to realize management information integration of ship to shore, a fuel testing system was developed. Using the force control configuration software, the realtime monitoring platform was developed. The examination organization main movement parameters, structure parameters, the fuel performance parameters were selected; through the flow data collection, conversion and transmission function test, the reasonable analysis about the data precision of marine fuel oil detection was done to find out the effect to the flow rate. Results show that the pump speed has the greatest effect on the flow, the second is the fuel oil viscosity, the realtime performance of the system meets the job requirements of the ship.
