HYDROSTATIC LEVEL INDICATOR Russian patent published in 1999 - IPC

FIELD: measurement technology. SUBSTANCE: hydrostatic level indicator is used to measure mass and volume of liquid in various tanks of large capacity employed to store clear oil products. Sensitive element of level indicator is manufactured in the form of two chambers 2 and 3 isolated one from another and positioned in rigid casing 1 and perforated plate 4 put on upper surface of chambers for sliding along generating line of casing in vertical plane. Gear to create backpressure is fabricated in the form of vessel 6 with piston 7 and rod 8 interacting via gearing with gear 9 of kinematic unit, two rigid links 13 with sliders-weighting materials 14. Radial guides 15 for travel of sliders-weighting materials 14 are made in side surfaces of gear 9. Measuring device is manufactured in the form of measuring vessel 17 with indicators of level 20 and pressure 22 of column of liquid in it. Vessel 6 to create backpressure communicates with chamber 2 of sensitive element which other chamber 3 communicates with measuring vessel 17. Simplicity of usage of level indicator is provided by its structure of constant action, expanded functional capabilities which allow registration of mass and volume to be carried out automatically and possibility of use of mass-produced units and parts for its manufacture. EFFECT: expanded functional capabilities. 3 cl, 2 dwg
