DEVICE MEASURING DENSITY OF LIQUID MEDIA Russian patent published in 1997 - IPC

FIELD: measurement technology, measurement of density of gasoline in reservoirs of gas filling stations and oil handling facilities. SUBSTANCE: device measuring density of liquid media has two intercoupled vessels, one having constant level, the other one being collecting vessel. Shut-off valve and throttle are mounted across outlet of second vessel, level indicators are placed in upper and lower planes, their outputs being connected to computation unit. Output of upper level indicator is connected to actuator via delay unit. EFFECT: simplified design, increased functional reliability. 2 cl, 1 dwg
