Ultrasound meter for determining the flow rate of a flowing medium

摘要

Ultrasonic flowmeter for measuring the flow rate of a flowing liquid or gas has a housing (1) that encloses a measuring section along which a differential time of flight measurement can be made using at least an ultrasonic transducer (2) and a ultrasound mirror (5) for guiding the sound beam. Fluid flow guiding elements are provided in the area of the mirror surface to optimize the fluid flow over the mirror surface. Independent claims are also included for the following:- (a) an ultrasound meter with an ultrasound deflection mirror holder (8) manufactured from two halves separated in a direction parallel to the longitudinal axis of the meter and; (b) an ultrasound meter with an ultrasound deflection mirror holder, mirror and measurement pipe that can be removed and inserted as a unit in the meter.
