Embodiment Construction

[0048] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0049] see Figure 1 to Figure 9 , an embodiment of an eight-channel ultrasonic flowmeter sensor, including a pipeline 1, the pipeline 1 is provided with two transducer mounts 2 along the axial direction, and the two transducer mounts are spaced apart from each other and arranged symmetrically. Eight mounting holes 21 are provided on the energy device mounting base, and each mounting hole communicates with the inner cavity of the pipeline. The eight mounting holes of the first transducer mounting base are two The axis lines of the two opposite installation holes are located on the same straight line, forming eight straight-through sound channels 3 respectively. The axis lines of each through-type sound channel intersect with the pipeline axis line at the same point, and The included angle between the axis line of the straight-through sound channel and the ax...

Abstract

The invention relates to an ultrasonic flow meter sensor with eight sound channels. The sensor comprises a pipeline, wherein two transducer mounting seats are axially mounted on the pipeline symmetrically at an interval, eight mounting holes are formed in each transducer mounting seat and communicated with the cavity of the pipeline, every two of the eight mounting holes of the first transducer mounting seat and every two of the eight mounting holes of the second transducer mounting seat are opposite, axes of the two pairs of opposite mounting holes are located on a same straight line to form eight through type sound channels, the axis of each through type sound channel and the axis of the pipeline are crossed at a same point and at an included angle of 36 degrees, an ultrasonic transducer is mounted in each mounting hole, every two pairs of ultrasonic transducers of the sixteen ultrasonic transducers are opposite to form eight groups of direct type ultrasonic transducers, and flanges are mounted at two ends of the pipeline respectively. The energy intensity and the flexibility are high, and the technical requirements on the transducers are low.

Description

technical field [0001] The invention relates to a flowmeter sensor, in particular to an eight-channel ultrasonic flowmeter sensor. Background technique [0002] Ultrasonic flowmeter (USF for short) is a measuring instrument that uses the propagation characteristics of ultrasonic waves in fluids to measure flow. Compared with traditional mechanical flowmeters and electromagnetic flowmeters, it has high measurement accuracy, strong adaptability to pipe diameter, non-contact fluid, convenient use, easy digital management, etc. It is widely used in electric power, petroleum, chemical industry, especially water supply system is widely used. [0003] The ultrasonic flowmeter is composed of a flowmeter body, an ultrasonic transducer and its installation parts, a signal processing unit and a flow computer. The ultrasonic transducer is made of piezoelectric elements such as cast ferrite lead. Fluid volume flow is measured by detecting the effect of fluid on an ultrasound beam (or p...
