ABSTRACT:
A flowmeter element is used for measuring a mass flow rate of fluid, and includes a semiconductor board, an ultrasonic unit and a pressure detecting unit. The ultrasonic unit performs at least one of sending ultrasonic wave and receiving ultrasonic wave. The pressure detecting unit detects a pressure of the fluid. The ultrasonic unit and the pressure detecting unit are integrally disposed on the semiconductor board.
