Small-diameter ultrasonic flow meter having opposing transducers
A small-diameter ultrasonic flow meter having opposing transducers comprises a circuit box (4), an outer pipe layer (1), an inner pipe layer (2), and a transducer assembly (3). The circuit box (4) is provided at the outer pipe layer (1). The inner pipe layer (2) is formed integrally by injection molding. Transducer installation bases (23) are formed at ends of the inner pipe layer (2). Transducer assemblies (3) are installed at the installation bases (23). The transducer assemblies (3) are arranged in pairs. The inner pipe layer (2) is installed inside the outer pipe layer (1). The transducer assemblies (3) are arranged opposite to each other to perform transmission and reception operations, thereby reducing energy loss. A standard pipe can be used as the outer pipe layer (1), thereby reducing costs. The inner pipe layer (2) can be assembled quickly and conveniently, provides accurate positioning, and has good sealing performance. No water exists in the entire cavity, thereby effectively protecting connection wires of the transducer assemblies (3) from being soaked in water, and providing an allowance space for deformation of the inner pipe layer (2) and a minor expansion of water turning into ice so as to effectively prevent freezing.
