Description
Technical Field
The utility model relates to an ultrasonic flowmeter measures technical field, specifically is an ultrasonic flowmeter measures auxiliary fixtures.
Background
Ultrasonic flow meters are meters that measure flow by detecting the effect of fluid flow on an ultrasonic beam (or pulse). The ultrasonic flowmeter can be divided into a propagation velocity difference method, a beam offset method and the like according to a detection mode, has the advantages of more convenient, economic and accurate measurement, and is widely applied to the fields of petroleum, chemical engineering, metallurgy and the like. An ultrasonic flowmeter is a non-contact instrument which can measure the medium flow of a large pipe diameter and can also be used for measuring a medium which is not easy to contact and observe. The device has high measurement accuracy, is hardly interfered by various parameters of the measured medium, and particularly can solve the problem of flow measurement of strong corrosive, non-conductive, radioactive and flammable and explosive media which cannot be measured by other instruments. The selected pipe section has great influence on the measurement precision, and the selected pipe section should avoid the conditions of interference and eddy current, which have great influence on the measurement precision. Secondly, the installation distance is to select a straight pipe section with the upstream more than 10 times of the straight pipe diameter and the downstream more than 5 times of the straight pipe diameter without any valve, elbow, reducing and the like, and the installation point is to be sufficiently far away from interference sources such as valves, pumps, high voltage electricity, frequency converters and the like.
