LIQUID LEVEL METER Russian patent published in 2002 - IPC

Abstract RU 2181191 C1

FIELD: measurement technology. SUBSTANCE: measurement of liquid level is based on measurement of pressure. Proposed meter includes unit for changing gas cavity volume, pressure pickup with secondary transducer and tube. Cavity of this tube is connected with pressure pickup and with reservoir of gas cavity volume changing unit. Volume of tube cavity is of the same order as volume of reservoir of gas cavity volume changing unit. Cavity of tube is communicated with liquid being measured and gas above it by means of holes located above and below level of liquid. EFFECT: enhanced accuracy of measurements; possibility of using meter in closed and open reservoir. 1 dwg
