Abstract

1363153 Measuring fluid-flow SIEMENS AG 26 Aug 1971 [5 Sept 1970] 40203/71 Heading G1R [Also in Division A5] In a flowmeter, such as is used for monitoring the lung function, two pressure transmission ducts 2, 3 disposed one behind the other and connected to a suitable differential pressure manometer, receive air from a multiplicity of narrow flow channels 8, formed between films 7 of polyvinyl chloride dividing the bore of a tube 1, through bores 9 and 10 ink collecting channels 11 and 12 associated respectively with the ducts 2 and 3.
