Device for measuring the flow velocity of a medium.

摘要

Flow measuring device with on a chip (18), four flat sensing resistors (R1, R3, R3 min , R4 min ) connected into two bridge configurations (1, 2), parallelly disposed but shifted over 90 DEG with respect to each other, each respective bridge output (9, 10, 11, 12) connected to the respective inputs of a differential amplifier (A1, A2) with the outputs (13, 14) of said amplifiers (A1, A2) connected to the inputs of a third differential amplifier (A3).
