中文摘要：

按照智能化、精度高、通用性强、性价比高的技术要求，针对槽道流量计提出采用硬件电路和软件优化算法相结合的方式对各检测流体的压力、温度、密度、压缩系数、黏性系数及可膨胀系数等参数进行相应补偿，使其适用于常用流体的测量，且精度大幅提升，可达0．3％～0．5％左右，从而在复杂现场构建一个多参数高精度的可靠性流量检测平台。

英文摘要：

In accordance with the requirement of intelligence, high precision, high universality, as well as high performanceprice ratio, the channel flowmeter was compensated by pressure, temperature, density, compressibility, swell factor, viscosity coefficient of fluids from the hardware and software aspects. Its universality was improved, and its precision has been substanlially upgraded to 0. 3% - 0. 5%. Thus a reliable flow collection platform with multi-parameters and high-precision performance is constituted that can be applied in complex field.
