Ultrasonic flow meter

Abstract

An ultrasonic flow meter is suitable for installation on a pipe fitting. The ultrasonic flow meter includes a clamping unit and a flow meter body. The clamping unit is used for installation on the pipe fitting and includes a base plate and a top seat disposed on the base plate. The base plate and the top seat together define a receiving channel for accommodating the pipe fitting. The top seat has a top mounting surface and a top opening located on the top mounting surface and communicating with the receiving channel. The flow meter body is disposed on the top mounting surface of the top seat of the clamping unit and partially extends into the receiving channel from the top opening. The flow meter body has two measuring protrusions extending into the receiving channel and abutting the pipe fitting.

Claims

1. An ultrasonic flow meter suitable for installation in a pipe fitting, the ultrasonic flow meter comprising: a clamping unit for installation in the pipe fitting, the clamping unit including a base plate and a top seat disposed on the base plate, the base plate and the top seat defining a receiving channel for receiving the pipe fitting, the top seat having a top mounting surface and a top opening located on the top mounting surface and communicating with the receiving channel; a flow meter body disposed on the top mounting surface of the top seat of the clamping unit and partially extending into the receiving channel from the top opening, the flow meter body having two measuring protrusions extending into the receiving channel and adjacent to the pipe fitting, wherein... The base plate has a plurality of first fixing parts, and the top seat has a plurality of fixing structures corresponding to the first fixing parts and positioned below the top mounting surface. Each fixing structure has a second fixing part, and the first fixing parts and the second fixing parts of the fixing structures are assembled and connected through a plurality of fasteners.

2. The ultrasonic flow meter as described in claim 1, wherein, The top seat also has a top plate having the top mounting surface, and two side plates extending downward from the top plate and connecting the fixing structures, each side plate having a clearance notch for avoiding the pipe and located between adjacent fixing structures.

3. The ultrasonic flow meter as described in claim 1, wherein, The flow meter body includes a measurement module and a main control and display module stacked on top of the measurement module. The measurement module is disposed on the top mounting surface of the top seat of the clamp unit and partially extends into the receiving channel from the top opening. The measurement module has two measurement protrusions that extend into the receiving channel and are adjacent to the pipe fitting.

4. The ultrasonic flow meter as described in claim 1, wherein, The top plate also has a top plate having the top mounting surface, a front plate and a rear plate extending downward from the top plate, and two positioning protrusions formed on the front plate and the rear plate respectively. The bottom plate also has two positioning recesses for correspondingly accommodating the two positioning protrusions.

5. The ultrasonic flow meter as described in claim 4, wherein, Each of the positioning recesses has two side positioning surfaces and an inner positioning surface connected between the two side positioning surfaces.

6. The ultrasonic flow meter as described in claim 5, wherein, The clamping unit also includes two soft pads respectively disposed in the two positioning recesses of the base plate. Each soft pad has two first covering portions covering the plate surface of the base plate, and a second covering portion connecting the two first covering portions and covering the inner positioning surface of the corresponding positioning recess. The second covering portion is used for the corresponding positioning protrusion to fit tightly against it.

7. The ultrasonic flow meter as described in claim 1, wherein, Both the base plate and the top seat are formed from metal sheets through a stamping process.
