Problems solved by technology

The principle of counting traffic is mainly through the rotation of mechanical gears, which is similar to the principle of mechanical watches. In this way, when the gear fails, it cannot continue counting, which is quite inconvenient, and someone may disassemble it for speculation. The device manually toggles the mechanical gear to change the data, resulting in inaccurate data

Embodiment 1

[0022] Such as Figure 1 to Figure 3 As shown, the nozzle flow meter of the present invention includes a nozzle main body 1, an inlet pipe 3 and an outlet pipe 4, in which the nozzle main body 1 is provided with a pipeline installation through hole 2, and the inlet pipe 3 and the outlet pipe 4 are separated from the pipeline respectively. The two ends of the installation through hole 2 are connected; the nozzle body 1 is provided with a data receiving and processing device, and the nozzle for the docking position of the inlet pipe 3 and the outlet pipe 4 is fitted in the pipe installation through hole 2 Mechanism, the data receiving and processing device cooperates with the nozzle mechanism through a signal acquisition device. The nozzle flow meter of the present invention, through the cooperation of the nozzle body 1, the inlet pipe 3, the outlet pipe 4, the pipe installation through hole 2, the data receiving and processing device, the nozzle mechanism and the signal acquisi...

Embodiment 2

[0024] On the basis of the above embodiments, in order to further better implement the present invention, the nozzle mechanism includes a first throttle ring 13 arranged at the butt end of the inlet pipe 3 and a second throttle ring 14 arranged at the butt end of the outlet pipe 4 , the nozzle 15 passing through the second throttle ring 14 is arranged on the first throttle ring 13; a signal collection port is arranged on the first throttle ring 13 and the second throttle ring 14 16. The two signal collection ports 16 are connected to the data receiving and processing device. After this design, when gas or liquid passes through the first throttle ring 13 and the second throttle ring 14, the gas or liquid in the first throttle ring 13 and the gas and liquid in the second throttle ring 14 can pass through the signal collection port 16 is transmitted to the data receiving and processing device, and the data receiving and processing device converts it into a pressure signal and ana...

Embodiment 3

[0026] On the basis of the above embodiments, in order to further better implement the present invention, the data receiving and processing device includes a mounting frame 7 detachably installed on the nozzle body 1, and a pressure sensor 8 and a pressure sensor 8 are installed on the mounting frame 7 A data operation processor 9, the data operation processor 9 is connected with an external data interface 10; the pressure sensor 8 is in communication with the signal collection port 16. The gas or liquid flowing out of the new drug collection port 16 reaches the pressure sensor 8, the pressure sensor converts it into a data signal and transmits it to the data operation processor 9, and the data operation processor 9 performs analysis and processing to obtain corresponding flow data, which can be obtained through external data The interface 10 transmits to external equipment, which is convenient for recording and practical. Preferably, the external data interface 10 adopts a mi...

Abstract

The invention relates to the field of flow meters, and particularly relates to a nozzle flow meter which is simple in structure, facilitates flow statistics and improves flow data accuracy. A pipelinemounting through hole is arranged in a nozzle main body, and an inlet pipe and an outlet pipe are connected from two ends of the pipeline mounting through hole; a data receiving and processing deviceis arranged on the nozzle main body, a nozzle mechanism matched with a butt joint position of the inlet pipe and the outlet pipe is arranged in the pipeline mounting through hole in a matched mode, and the data receiving and processing device is matched with the nozzle mechanism through a signal collecting device. According to the nozzle flow meter, during use, a gas or a liquid enters from the inlet pipe; the water flows out from the outlet pipe through the nozzle mechanism; and a pressure difference is formed between the two ends of the nozzle mechanism, the signal collecting device collects pressure data at the two ends of the nozzle mechanism and transmits the pressure data to the data receiving and processing device for analysis and processing, corresponding flow data are obtained incombination with the pressure difference, the structure is simple, flow statistics is facilitated, and the flow data accuracy is improved.

Description

technical field [0001] The invention relates to the field of flow meters, in particular to a nozzle flow meter with simple structure, convenient flow statistics and improved accuracy of flow data. Background technique [0002] Flow meters, especially gas flow meters, are often used in daily life. For example, natural gas meters must be used to calculate the amount of natural gas used by users. At present, the commonly used gas meter is measured by detecting the actual flow of gas. The principle of counting the flow is mainly through the rotation of mechanical gears, which is similar to the principle of mechanical watches. In this way, when the gear fails, it cannot continue to count, which is quite inconvenient, and someone may disassemble it for speculation. The device manually toggles the mechanical gears to change the data, resulting in inaccurate data. Contents of the invention [0003] Aiming at the defects in the prior art, the invention provides a nozzle flowmeter...
