DISCRETE LEVEL GAUGE Russian patent published in 2003 - IPC

FIELD: instrumentation engineering, measurement of level of liquid in closed volume. SUBSTANCE: discrete level gauge has float with constant magnet, non-magnetic pipe placed vertically, hermetically sealed reed relay, indicator, controlling microcontroller, reversible motor, discrete detector of turning angle, drum with helical surface, cable with non-magnetic weight, photosensors of start of reading and operation of contacts of hermetically sealed reed relay, bearing plate, additional constant magnet, non-magnetic limiter, blinds. Cable is produced from flexible conductor, is attached with one end to drum and is placed inside non-magnetic pipe. Additional magnet and non-magnetic limiter are made fast to lower end of non- magnetic pipe. Blinds are mounted freely of upper end of pipe. Controlling microcontroller is connected to reversible motor and photosensors. Contacts of hermetically sealed reed relay are linked to cable. EFFECT: reduced measurement error. 1 dwg
