| Zusammenfassung: | The utility model belongs to a micro-quantity gas flow meter used for automatic measurement of a patient's quantity of respiratory oxygen in a hospital. The utility model is composed of a float-type gas flow meter 1 and is characterized in that a search coil is winded on an inner glass tube A of the float-type gas flow meter 1, two ends I1 of the search coil 2 connect with the input end I1'of an oscillator 3, and the output end I2 of the oscillator 3 connects with a measuring end I2'of a detection system 4. The utility model is a new micro-quantity flow meter automatically measuring air flow with high measuring precision. |
