Title:
FLOW RATE MEASUREMENT DEVICE, GAS METER PROVIDED WITH FLOW RATE MEASUREMENT DEVICE, AND FLOW RATE MEASUREMENT DEVICE UNIT FOR GAS METER
Document Type and Number:
WIPO Patent Application WO/2019/054030
Kind Code:
A1
Abstract:
This flow rate measurement device provides a technology that makes it possible to more accurately measure and output a flow rate according to the purpose of use. A flow rate measurement device (1) detects the flow rate of a fluid to be measured flowing in a main flow path (2) and is provided with: a heating unit (113) that heats the fluid to be measured; a plurality of temperature detection units (111, 112) that are disposed with the heating unit interposed therebetween in the flow direction of the fluid to be measured and that detect the temperatures of the fluid to be measured; and a conversion unit (133) that converts the difference between the outputs of the plurality of temperature detection units to the heat flow rate or heat amount of the fluid to be measured flowing in the main flow path.
