Abstract: 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.

Abstract translation: 一个小而轻的流量计实现了零点漂移的补偿。 质量流量计包括：离心力/向心力检测应变计，其粘附在通过流体流动的管道中的离心力或流体向心力作用的部分上，并且流量零点漂移补偿应变计粘附 到与离心力/向心不同的位置，力检测应变仪。 使用两点之间的脉搏波传播时间来补偿流量的零点漂移。
