摘要
介绍能够测定空气质量流量,且可自动补偿温度及压力变化对空气流量影响,测量精度高的热膜式气体质量流量计的原理、构造和性能。这种流量计可以满足各种发动机进气流量测量,特别是排放测试的需要。
Elaboration has been made on the design concept, construction and characteristic of a thermal type gas massflowmeter, which has the advantage of being capable of testing air mass flow and automatically counterpoising the effect oftemperature and pressure variations on air flow, and features high testing accuracy. The thermal flowmeter of this designcan satisfy the intake air flow measurement of various engines, and meet the requirement of exhaust emission test in particular.
