Abstract

The related multifunctional gas measurer comprises a body; wherein, in the body, there is connected by turns an inlet / outlet pipe, a constant temperature tube, a buffer tank with liquid, a measuring tube with a temperature / liquid-level sensor and open top, and a data processing display. Based on U-shaped tube principle, this invention overcomes defects in prior art, improves structure, and has wide application.

Description

technical field [0001] The invention relates to a device for measuring gas volume, in particular to a multifunctional gas production measuring instrument. Background technique [0002] At present, flowmeters are mainly used to measure the volume of gas in the field of determination of the volume of gas generated by chemical, physical or biological reactions such as laboratory testing, scientific research, and factory on-line monitoring. For example, there are 10 types of flowmeters for online gas volume measurement in industry, and there are about 100 kinds; there are also 4 types of flowmeters for gas volume measurement in laboratories. However, the existing flowmeters for measuring gas volume measure continuous, fixed flow or regularly generated gas volume. For those intermittent, non-fixed flow or irregular chemical, physical or biological gas generation reactions, existing flow meters for measuring gas volume cannot be measured. Contents of the invention [0003] In ...
