Hot-wire type flowmeter

摘要

A hot-wire type flowmeter for measuring a flow rate of a fluid in a passage comprises a pair of support pins extending in parallel with an axis of the passage and an electrical resistor supported between the support pins in the passage. The resistor includes a pipe made of an electrically insulating material, a resistor wire wound on the pipe, and a pair of lead wires. The lead wires are secured to opposite end portions of the pipe and extend in opposite directions and in parallel to each other. The resistor is supported by the support pins through the lead wires.
