Experiment and analysis of movable weir for flow measurement indicate that the modular limit of movable weir is relatively high. And the accuracy of theoretical discharge calculated is satisfied.

The test results have proved that the flow rate widely varied and the pump efficiency is high when the pump outlet line structure was altered and the outlet pressure was controlled in a special limit.

Using a small flow number atomizer may obviously improve the lean ignition limit of the high density fuel, but the ignition velocity-pressure limit and the rich ignition limit are shrunk.
