Abstract
The utility model discloses an electronic measuring cylinder. The electronic measuring cylinder comprises an illuminant, a collimating lens, a slitting board, a cover of a glass measuring cylinder, a needle-cylinder type glass measuring cylinder, a location-sensing sensor panel, a microprocessor and a figure display screen. Light emitted from the illuminant is collimated by the collimating lens and irradiates to the slitting board to photoetch per slit. The light penetrates through the cover of the glass measuring cylinder and the needle-cylinder type glass measuring cylinder to irradiate to the location-sensing sensor behind the corresponding slits. While liquor level of the needle-cylinder type measuring cylinder rises per slit, the intensity of probe light of the location-sensing sensitive sensor in the corresponding position is weakened by the liquor. Then the figure is accumulated by the microprocessor and is displayed on the figure display screen till the required volume of the liquor is measured. The electronic measuring cylinder has the advantages that the minimum volume of the measured liquor is 0.5 mm and the precision is 0.5 mm. The needle-cylinder structure and a separation structure are adopted, and therefore the electronic measuring cylinder has the advantages of being easy and convenient to measure and accurate and reliable in numerical reading.
