WATER FLOW CURRENT SENSOR

摘要

PROBLEM TO BE SOLVED: To improve measurement reproducibility in a water flow current sensor provided with the heating part and a plurality of temperature measurement elements arranged around the heating part, by reducing irregularity of a water temperature distribution around a sensor caused by convection of water due to heat in a heating part. SOLUTION: In a rod 6 arranged around the heating part 14 and provided with a built-in thermistor 17, an upper part 6c of an inside rod 6a is bent so as to be brought into contact with the side wall face of the heating part 14.
