Abstract
FIELD: measurement technology. SUBSTANCE: invention refers to graduation of measurement devices determining flow of gas or liquid with the aid of ultrasound. Device is portable, mobile one which operation does not depend on presence of external vibrations and changes of ambient temperature. It is attended and moved by one specialist in the field. In compliance with formula of invention electroacoustic converters of flowmeter to be graduated are attached to unit manufactured from hard sound-conducting material providing for stable acoustic contact between these converters. Such unit may be manufactured in the form of prism from acrylic plastic. Proposed design of unit ensures high stability of time of propagation of sound in device for graduation of ultrasound flowmeters. It is possible to sink lower boundary of graduated limit of measurements up to 6.5 cu.m/h and below without installation of additional electroacoustic converters thanks to increased stability of graduation process. EFFECT: expanded measurement range and stability.
