[0028] like Figures 1 to 4 As shown, an easy-to-install external clamp-on ultrasonic flow meter is characterized by: a flow meter body 1 and a fixed bracket 2, wherein a sliding assembly 3 is provided on the fixed bracket 2, the sliding assembly 3 includes a first sliding device 301 and a second sliding device 302, and a fixing steel strip 201 is provided on both sides of the fixed bracket 2 for connecting to the pipe device being measured; a bracket guide rail groove 202 is provided on the fixed bracket 2 for the first sliding device 301 and the second sliding device 302 to slide in the horizontal direction; and a measuring scale 4 is also provided on the upper part of the first sliding device 301 and the second sliding device 302 for measuring the distance between them.

[0029] The first sliding device 301 includes a sliding support 3011 and a movable pressure rod 3012. The movable pressure rod is located at the upper middle position of the sliding support 3011 and is fixedly connected through a fixing through hole. A compression spring 3013 is installed at the lower part of the movable pressure rod 3012. One side of the compression spring 3013 is connected to a connecting plate 3014. A measuring sensor 3015 is installed at the lower part of the connecting plate 3014. The flowmeter body 1 is also provided with a connecting wire hole 101, which is connected to the inside of the measuring sensor 3015 for easy reading of flow measurement data. The two protrusions on both sides of the sliding support 3011 are inserted into the bracket guide rail groove 202. The two sides of the bracket guide rail groove 202 are symmetrically and parallelly arranged.

[0030] The measuring scale 4 is provided with a scale through hole 401, which is parallel to the bracket guide rail slide groove 202 in the horizontal direction. The measuring scale 4 is provided with a scale on one side to facilitate the measurement of the relative position distance between the first sliding device 301 and the second sliding device 302.

[0031] The fixed bracket 2 has steel strip mounting grooves 204 on both horizontal ends. These grooves are used to securely mount the steel strip 201, preventing it from slipping horizontally from within the grooves. A slide rail 203 is provided on the upper part of the bracket guide rail groove 202. The upper surface of the slide rail 203 has multiple rectangular dividing frames of equal size to facilitate parallel alignment with the measuring scale 4. A sliding protrusion 3016 is provided on the upper end of one side of the sliding support 3011. This protrusion assists in aligning with the measuring scale 4 for reading.

[0032] The first sliding device 301 and the second sliding device 302 are completely identical in terms of their overall structural components. The fixed through hole in which the movable pressure rod 3012 contacts the sliding support 3011 is threaded. By rotating the movable pressure rod 3012, the vertical distance of the movable pressure rod 3012 is adjusted, and the adjustment is transmitted to the connecting plate 3014 through the compression spring 3013, thereby adjusting the vertical height of the measuring sensor 3015. The bottom side of the measuring sensor 3015 is in close contact with the outer wall of the pipe being measured.

[0033] Operating Principle: When using this device for fluid flow measurement, a fixing steel strip is first installed on the steel strip mounting grooves at both ends of the fixed bracket. This steel strip quickly wraps around and secures the measuring pipe. Since the length of the fixing steel strip is selectable, it can adapt to measuring pipes of different outer diameters. This demonstrates the device's strong practicality and adaptability. A first sliding device and a second sliding device are installed on the fixed bracket, each containing a corresponding measuring sensor. A measuring scale is installed on the upper part of the first and second sliding devices, allowing for quick adjustment to determine the displacement distance between adjacent measuring sensors. Operation is simple, convenient, and reliable. The entire device has a compact and simple structure, low manufacturing and operating costs, and is suitable for large-scale use. For fixing the measuring sensor, the connecting plate 3014 is adjusted by rotating the movable pressure rod 3012 on the sliding support. The connecting plate 3014 affects the vertical adjustment of the measuring sensor 3015, allowing for quick and appropriate vertical positioning.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
