Embodiment Construction

[0023] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0024] The invention provides an electronic soap film flowmeter with automatic foam generation.

[0025] Such as figure 1 and figure 2 Shown, in this device, soap pipe 11 upper end has air outlet 10, and soap pipe 11 bottom side has air inlet 12; The column 1 in the soap pipe support system adopts the carbon steel or the stainless steel round bar with external thread at the lower end, can It is connected with the base 2 with internal thread at the lower part through threads, which is convenient for disassembly and assembly. Four foot pads 3 are evenly distributed on the lower part of the base 2, which are made of rubber or silica gel, and play a shock-absorbing role, and are bonded to the bottom of the base 2 by superglue. The upper bracket 6, the lo...

Abstract

The invention provides an electronic soap film flowmeter automatically producing bubbles and belongs to the technical field of flow determination. The flowmeter consists of a soap tube, a soap tube supporting system, a photoelectric sensing system, a liquid level lifting system and a liquid level adjusting system. A magnetic force is produced by utilizing direct current through multi-turn coils and combines with the elastic force of a spring itself, a heavy hammer is driven to immerse into and float out of liquid by pushing and pulling a magnetic push-and-pull rod to ascend and descend, and the liquid level is lifted and reduced according to the Archimedes law to cause periodic rise and fall of the liquid level in the soap tube. Due to the damping effect of a communicating guide tube, the liquid level rising and falling speed is low, so that there is sufficient time for contact between a measured air source and soap liquid, thin soap bubbles are formed at first during liquid level falling, and the soap bubbles gradually become larger when the liquid level continues to fall and are finally separated from the liquid level to form a soap film. The process can be automatically controlled through an upper computer or a single chip microcomputer.

Description

technical field [0001] The invention relates to the technical field of flow measurement, in particular to an electronic soap film flowmeter with automatic foam generation. Background technique [0002] Soap film flowmeter is a volumetric flowmeter that uses the volume between soap films to measure gas flow. It is necessary to accurately measure the start time and end time of the two soap films before and after. Usually, direct reading of the scale and manual Timing is achieved. The electronic soap film flowmeter is a device that can measure the tiny gas flow formed by installing a pair of photoelectric sensors on the direct-reading glass tube soap film flowmeter. The defect of error improves the measurement accuracy, and at the same time, simplifies the operation steps and improves the measurement efficiency. The measured flow range is 12~60L / min. Widely used in teaching and scientific research, environmental monitoring, physical and chemical analysis and other fields. ...
