Abstract
A temperature-sensitive mass flowmeter includes a detecting element, a signal receiving element, and a signal processing element. The detecting element includes a first sensing element and a second sensing element. The first sensing element and the second sensing element are each a nanotube composite wire. The carbon nanotube composite wire includes a carbon nanotube wire and a metal layer. The carbon nanotube wire includes a plurality of carbon nanotubes spirally arranged along an axial direction of the carbon nanotube wire and the metal layer is coated on a surface of the carbon nanotube wire.
