摘要： A flow rate sensor is disclosed, comprising a flow rate calculation part that calculates a flow rate of a fluid based on an expression using Xd/Xu that satisfies an expression at least in a certain range of the flow rate when an output of a constant temperature control circuit corresponding to an upstream resistor is defined as Vu, an output of a constant temperature control circuit corresponding to a downstream resistor is defined as Vd, and the flow rate is defined as and the flow rate calculation part corrects the zero point output as being an output when the flow rate is zero by using a zero offset function (OFS) defined as a function of Vu+VdXd/Xu.
摘要翻译：公开了一种流量传感器，包括：流量计算部，其基于使用Xd / Xu的表达式计算流体的流量，所述表达在满足表达式时至少在一定的流量范围内，当恒定温度的输出将与上游电阻对应的控制电路定义为Vu，将与下游电阻对应的恒温控制电路的输出定义为Vd，将流量定义为流量计算部，将零点输出校正为通过使用定义为Vu + VdXd / Xu的函数的零偏移函数（OFS），流量为零时的输出。
