ABSTRACT:
A device for measuring at least one characteristic of a fluid is provided. The device comprises a measuring channel which is designed for conducting fluid flow therethrough and which is defined by a wall and a substrate. An inlet orifice and an outlet orifice are provided for conducting fluid into and out of the measuring channel and at least one sensor is located adjacent the measuring channel for measuring the characteristic of the fluid. The wall has outer portions, which are sealing adhered to the substrate, and upwardly bent portions, which partially define the measuring channel. The outer portions and the upwardly bent portions are of substantially the same thickness. The wall is preferably made of a synthetic resin, glass, ceramic, silicon nitride, silicon monoxide, silicon dioxide, or combination of these materials.
