A low-cost sensitive flowmeter



A low-cost sensitive flowmeter



Journal of Physics E: Scientific Instruments 16(3): 190-192



A low-cost turbine flowmeter has been designed for studies of water thermosyphoning. It was built from an ordinary medical 'spinhaler' inhalent impeller and was capable of measuring flows down to 1.7 ml/s. It caused a pressure loss of 5 mm head of water (50 Pa) at a flow of 20 ml/s. The head loss could be reduced to 2 mm (20 Pa) at 20 ml/s, but the smallest detectable flow was then 10 ml/s.
