An insertable ultrasonic gas flow meter

Abstract

This utility model discloses an insertion-type ultrasonic gas flow meter, including a flow meter body. A control panel is mounted on the front of the flow meter body, and multiple connectors are mounted on the bottom of the flow meter body. A support assembly is mounted on the outer surface of the flow meter body, and a protective assembly is mounted on the back of the flow meter body. A winding assembly is installed inside the protective assembly. By mounting the protective assembly on the back of the flow meter body, this device allows the connecting wires between the two insertion-type sensors and the flow meter body to be wound around the outer surface of the winding cylinder in the winding assembly. This facilitates the storage of the connecting wires, and the protective assembly reduces contact between the connecting wires and the external environment, preventing cracking and increasing the device's service life. Therefore, this device effectively solves the problem of existing devices being prone to damage due to prolonged exposure of the connecting wires.

Description

Technical Field

[0001] This utility model relates to the field of flow meters, and in particular to an insertion ultrasonic gas flow meter. Background Technology

[0002] Ultrasonic flow meters are instruments that measure the flow rate of liquid in a circular pipe based on the velocity difference method. They adopt advanced multi-pulse technology, digital signal processing technology, and error correction technology, making the flow meters more adaptable to industrial environments and providing more convenient, economical, and accurate measurement. The products have reached advanced levels both domestically and internationally and can be widely used in petroleum, chemical, metallurgical, power, water supply and drainage and other fields.

[0003] Chinese Patent CN218511814U discloses an insertion-type ultrasonic gas flow meter, including a wall-mounted main unit and two sets of insertion sensors connected to the wall-mounted main unit. It also includes a suction cup assembly fixedly installed on the back of the wall-mounted main unit and an air intake and exhaust mechanism fixedly connected to the top of the suction cup assembly. However, the existing device still has some shortcomings. Existing insertion-type ultrasonic gas flow meters generally use two insertion sensors that are inserted into the pipe to detect the gas in the pipe. However, during the use of insertion sensors, they need to be connected to the flow meter body through a long connecting cable to analyze the gas detection data. However, the long connecting cable is prone to tangling, and long-term exposure may cause cracking, resulting in damage to the device. Therefore, we propose an insertion-type ultrasonic gas flow meter to solve the above problems. Utility Model Content

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] 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.

The winding component 5 includes a winding cylinder 13, which is located on the back of the flow meter body 1. A connecting wire is wound on the outer surface of the winding cylinder 13, and a threaded baffle 14 is threadedly connected to the back of the winding cylinder 13, which can conveniently wind the connecting wire in the device onto the outer surface of the winding cylinder 13, thereby storing the connecting wire.

The two long threaded rods 19 enable the two sets of clamping plates 8 to be clamped on the outer surface of the pipe, making the device easy to install.

[0027] The working principle of this utility model is as follows:

[0028] When using this insertion-type ultrasonic gas flow meter, the operator first places the device in a suitable position and fixes it in the installed pipeline using the support component 2 below the device. Next, the connecting wires between the two insertion sensors and the flow meter body 1 are wound around the outer surface of the winding cylinder 13 in the winding component 5, leaving an appropriate length of connecting wire. Then, the wound connecting wires are fixed by the fixing component 4, and the protruding connecting wires are fixed by the clamping component 6. Then, the two insertion sensors are inserted into the pipeline for detection. Finally, the operator controls the flow meter body 1 to detect the gas in the pipeline.
