Abstract：The intelligent balanced flowmeter consists of a throttle orifice plate and an intelligent transmitting apparatus. As a new differential pressure type flowmeter，it’s based on law of conservation of energy，and used multi?鄄holes orifice with integrated structure to makes fluid throttled and balanced. The applied practice in energy management system indicated that it has the advantages of low pressure loss，high accuracy，wide rangeability，low installation requirement and little possibility of blockage.
