HOT WIRE TYPE AIR FLOWMETER

摘要

PURPOSE:To obtain a hot wire type air flow meter capable of shortening the time required in the disassembling of a product and enhanced in recycle properties by the constitution using a snape-fitting connector in the connection of a body and a module case containing a drive circuit. CONSTITUTION:A hot wire type air flowmeter is constituted of a body 1 constituting the passage of a sucked air flow rate 8, the hot wire 3 measuring said air flow rate, a cold wire 4 measuring the circumferential temp. at the time of the measurement of the air flow rate and a module case containing the drive circuit driving the wires 3, 4. A snap-fitting connector 5 is used in the connection of the body 1 and the module case 2. The connector 5 is formed by the integral molding with a resinous pin, the body or the module case 2.
