3 Overview

3.1 Use A soap membrane flow meter (hereinafter referred to as a flow meter) is a flow meter that measures the flow rate of a small gas. Direct reading glass Tube soap membrane flowmeter (hereinafter referred to as soap membrane flowmeter) and a soap membrane flowmeter with a pair of electronic sensors mounted on the soap tube (hereinafter referred to as electronic soap membrane flowmeter). Direct reading glass tube soap membrane flowmeter, the maximum flow is generally 12L/min. Electricity The sub-soap membrane flowmeter, the maximum flow rate is generally 60L/min. When the soap membrane flowmeter needs to be used as a device, it should be The relevant provisions of Appendix B. 3.2 Structure type The soap membrane flowmeter is a soap tube with a scale, and there is an air inlet under the soap tube, the lowermost end of the soap tube A rubber ball is attached, and the rubber ball is filled with a soap solution. The electronic soap membrane flowmeter is equipped with a lower limit sensing on the outer wall of the soap tube tube. And upper limit sensors are equipped with display instruments. The structure of the soap membrane flowmeter is shown in Figure 1. The structure of the electronic soap membrane flowmeter is shown in Figure 2. 3.3 Working principle As shown in Figure 1 and Figure 2, the working principle of the soap membrane flowmeter is the gas flowing out of the gas source, which is regulated by flow.
