Embodiment
The utility model provides a kind of two-channel ultrasonic flowmeter pedestal, including base body 1, the inside of base body
With gas passage 2, gas passage is typically in a diameter of DN25mm ~ 200mm of cylindrical, preferably gas passage.Pedestal sheet
Body is provided at both ends with ring flange 3, and ring flange is the basis that base body is connected with pipeline, and installation sealing is provided with ring flange
The pad groove 4 and bolt hole of circle；Ring flange is typically also configured with pipeline, both are coordinated by bolt is connected and sealed.
Two groups are provided with base body and is used to installing the mounting holes 5 of ultrasonic probe, mounting hole 5 is directly and gas passage
2 communicate, and the ultrasonic probe of installation flushes with the inwall of gas passage.It is preferred that the front and back set on base body is all provided with
It is equipped with two mounting holes, the angle of ultrasonic probe and base axis is 35 degree ~ 55 degree, and upper and lower offset distance is 2.5mm ~ 10mm, partially
