MASS FLOWMETER

摘要

A mass flowmeter having zero-point drift compensation using a small, lightweight flowmeter is provided. A strain gauge for detecting centrifugal force or centripetal force is attached in a location where centrifugal force or centripetal force of a fluid acts inside a conduit in which a fluid flows through the interior, and a strain gauge for zero-point drift compensation of a flow rate is attached in a position different from the strain gauge for detecting centrifugal force or centripetal force. The mass flowmeter compensates zero-point drift of a flow rate using the pulse wave propagation time between two these two points.
