Problems solved by technology

[0005] (2) Additional errors caused by soap liquid backflow after soap film rupture
[0007] (4) Accurate control of the calibration process
For a soap film flowmeter with a smaller size (volume 25ml), the error reaches ±0.2%, which reduces the accuracy level of the flowmeter

Abstract

The invention provides a soap film flow meter with an automatic film opening function. The soap film flow meter comprises a soap film pipe, a soap film producing device and a soap film recycling device. The soap film producing device comprises a liquid soap pipe and an air inlet pipe, and the air inlet pipe is arranged on the upper portion of the liquid soap pipe; the soap film recycling device comprises a soap film recycling cover, a liquid soap recycling pipe and a liquid soap recycling cup, one end of the liquid soap recycling pipe is connected with the liquid soap recycling cover on the top of the soap film pipe, and the other end of the liquid soap recycling pipe extends into the liquid soap recycling cup; the liquid soap recycling cup is filled with liquid soap, the bottom of the liquid soap pipe is connected with a side wall of the bottom of the liquid soap recycling cup, and the liquid level of the liquid soap and the top of an air inlet of the air inlet pipe are positioned at the same altitude. The soap film flow meter has the advantages that an automatic film opening mode can be implemented by the aid of a communicating vessel principle, accordingly, shortcomings of a manual film opening mode can be overcome, and verification errors can be reduced.

Description

technical field [0001] The invention relates to an automatic film opening type soap film flowmeter, which belongs to the technical field of machinery. Background technique [0002] With the continuous development of modern science and technology, improving process control and accurate flow measurement have become very important technical issues. Especially for tiny gas flow, the control of flow, air flow will be affected by ambient temperature and pressure, which will lead to large difference in gas flow, and the accuracy may also be affected by various factors. Therefore, in order to correctly measure and transmit flow data, it is necessary to study a suitable gas flow standard device for the above conditions. [0003] At present, the soap film flowmeter is one of the main flowmeters for measuring the flow of tiny gases. The main part is a glass tube with a smooth inner wall and as uniform inner diameter as possible. Use the soap film flowmeter to ventilate the soap film ...
