摘要：
A small and light-weight flowmeter realizes the compensation of a zero point drift. A mass flowmeter includes: a centrifugal force/centripetal force detection strain gauge adhered to a part acted upon by a centrifugal force or a centripetal force of fluid in a pipe line in which the fluid flows and a flow rate zero point drift compensation strain gauge adhered to a position different from that of the centrifugal force/centripetal force detection strain gauge. A pulse wave propagation time between the two points is used to compensate a zero point drift of a flow rate.
