Flowmeter
First Claim
1. A flowmeter comprising:
- a pair of fluid pipes forming a flow path for allowing a measurement fluid to flow therethrough, having a substantially equal shape and equal size with each other, and arranged to be substantially mirror-symmetric and parallel;
an oscillator including a coil and a magnetic substance for oscillating the fluid pipes;
a plurality of detectors disposed to be spaced apart from each other along the flow path of the fluid pipes and including a coil and a magnetic substance for detecting a state of vibration of the fluid pipes; and
a calculator that calculates a mass flow rate of the measurement fluid that passes through the flow path of the fluid pipes based on each vibration that is detected by the plurality of detectors,the flowmeter further comprising;
a supporting base to which an end portion of each of the fluid pipes is mounted and which supports each of the fluid pipes in a manner capable of being vibrated; and
a frame fixed to the supporting base,wherein the frame is integrally formed with a mounting portion disposed between the pair of fluid pipes and having a thickness that does not interfere with the pair of fluid pipes, a reinforcing portion disposed at an outer circumference of the mounting portion and enhancing a rigidity of the mounting portion, and a fixing portion for being fixed to the supporting base,the reinforcing portion has an outer wall portion that protrudes at least to one side of a thickness direction of the mounting portion, and substantially continuously surrounds an outer circumference of the fluid pipes, andpenetrating portions for disposing the coils corresponding to the respective magnetic substances mounted on the fluid pipe are formed in the mounting portion.

Abstract
A flow meter of Coriolis type includes a supporting base that supports a pair of fluid pipes in a manner capable of being vibrated, and a frame fixed to the supporting base. The frame is integrally formed with a mounting portion disposed between the fluid pipes and having a thickness that does not interfere with the fluid pipes, a reinforcing portion disposed at the outer circumference of the mounting portion and enhancing the rigidity of the mounting portion, and a fixing portion for being fixed to the supporting base. The reinforcing portion has an outer wall portion that protrudes at least to one side of the thickness direction of the mounting portion, and substantially continuously surrounds the outer circumference of the fluid pipes. Penetrating portions for disposing the coils corresponding to respective magnetic substances mounted on the fluid pipe are formed in the mounting portion.
