Abstract
PURPOSE: To obtain the flowmeter which can measure the low flow rate automatically, by detecting the rise time of liquid film of soap water formed in the measuring cylinder with two photoelectric sensors provided in the cylinder.
CONSTITUTION: One of the flow-in tube to which has gas to be measured flows is connected to the bypass ring 11 via the valve 17 and another is connected to the measuring cylinder 1 via the valve 16 and soap water chamber 12, and a part of soap water in the water chamber 12 is contained in the bag 14 containing soap water in the pressurized chamber 13. Further, the valves 18W20 are operated, the liquid level 21 of the soap water is moved by pressing the bag 14 to form the liquid film of soap water under the measuring cylinder 1 and the valve 16 is opened to flow the gas for measuring from the flowing tube 15 to the measuring cylinder. Then, the liquid film 25 for soap water rises in the measuring cylinder according to the flow rate of gas. The time of rising is detected with the 1st, and 2nd photoelectric sensors 4, 5 and 8, 9 and it is measured by the counter 10 to obtain the flow rate.
