摘要 |
A flow measuring apparatus includes a resistance layer for detecting a flow rate within a passage and an additional resistance layer for burning off deposits formed by suspended particles the like, and both of the resistance layers are formed on only one substrate. When suspended particles are deposited on the substrate to form deposits thereon, the deposits are burned off and removed from the substrate by supplying power to the additional resistance layer.
