Title:
FLOW MEASURING INSTRUMENT
Document Type and Number:
Japanese Patent JP3473598
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a flow rate measuring instrument that can measure flow rates with high accuracy by offsetting error components caused by flow rate calculation.
SOLUTION: This flow rate measuring instrument is provided with at least one set of vibrators 11 which are installed on a fluid pipeline 10 and transmit and receive ultrasonic signals, a transmitting means 12 which oscillates a prescribed frequency, and at least one set of transmitting means 15 which are positioned between the vibrators 11 and transmitting means 12 and transmit signals to the vibrators 11. This measuring instrument is enabled to perform high-accuracy flow rate measurement by offsetting the error components caused by flow rate calculation by making the characteristics of the transmitting means 15 equal to each other.
