Problems solved by technology

However, industrial sites often have harsh environments, complex distribution of pipelines, and many elbows, valves, and variable diameters. In many cases, it is difficult to meet the stringent requirements of the instrument on the straight pipe section of the flowmeter, and the accuracy of the instrument is greatly reduced, especially in important occasions. time, it will bury hidden dangers for the safety of the production process
[0003] In order to ensure the measureme...

Embodiment Construction

[0013] In order to make the content of the present invention easier to be understood clearly, the following further describes the present invention in detail based on specific embodiments in conjunction with the accompanying drawings.

[0014] according to figure 1 , The present invention includes a flow meter pipe 4, a flow measuring part 2, a rectifier 1. The flow meter pipe 4 has a built-in rectifier 1 at the front end to enable it to set the flow field. The flow meter pipe 4 and the rectifier 1 are welded together as As a whole, the distance between the rectifier 1 and the flow measuring part 2 is 3 to 5 times the diameter of the flow meter pipe 4. The two ends of the flow meter pipeline 4 are provided with connecting flanges 3 for connection with the process pipeline. The plug-in probe 6 of the flow measuring part 2 is inserted into the flow meter pipe 4, and the flow measuring part 2 is welded to the flow meter pipe 4 as a whole. The flow meter pipe 4 is provided with a f...

Abstract

The invention provides a thermal type gas mass-flow meter internally provided with a rectifier. The thermal type gas mass-flow meter comprises a flow meter pipeline, a flow measuring part and the rectifier. The thermal type gas mass-flow meter is characterized in that the rectifier is arranged in the front end of the flow meter pipeline, the flow meter pipeline and the rectifier are connected into a whole, and the distance between the rectifier and the flow measuring part is 3-5 times of the diameter of the flow meter pipeline. The thermal type gas mass-flow meter has the advantages that the thermal type gas mass-flow meter is directly installed, and the influence of a straight pipe section of the flow meter pipeline on the flow meter does not need to be considered; the rectifier and the flow meter pipeline are designed in an integrated mode, exposed points of the pipeline are effectively reduced, labor cost is reduced, installation time is saved, and high cost performance is achieved.

Description

Technical field [0001] The invention relates to a gas mass flow meter, in particular to a thermal gas mass flow meter with a built-in rectifier, which can measure a full-tube single-phase fluid of gas, vapor, liquid and other media. In principle, it is a direct gas measurement Mass flow meters do not require conventional temperature and pressure compensation, and can be used in petrochemical, metallurgical, and electric power industries. Background technique [0002] Since the thermal gas mass flowmeter measures the flow according to the principle of thermal diffusion, and the plug-in probe of the flow measurement part is only installed at the center point of the flowmeter pipe, the flow is obtained from the point flow, so the length of the straight pipe section of the flowmeter when in use Must meet the length of more than 15 times the diameter of the flowmeter pipe, so that the fluid is in a fully developed steady flow state. However, industrial sites often have harsh environm...
