Title:
FLOW MEASURING DEVICE, GAS METER HAVING FLOW MEASURING DEVICE, AND FLOW MEASURING DEVICE UNIT FOR GAS METER
Document Type and Number:
Japanese Patent JP2019052962
Kind Code:
A
Abstract:
To provide a flow measuring device capable of more accurately measuring and outputting the flow corresponding to intended purposes.SOLUTION: A flow measuring device for detecting the flow of a measuring object fluid flowing in a main flow path comprises a heating part for heating the measuring object fluid, a plurality of temperature detection parts for detecting the temperature of the measuring object fluid, disposed opposite to the heating part across the flow direction of the measuring object fluid, and a conversion part for converting the difference in the output of the temperature detection parts into the heat flow or heat of the measuring object fluid flowing in the main flow path.SELECTED DRAWING: Figure 17
