DEVICE FOR MEASURING LEVEL AND DENSITY OF LIQUID Russian patent published in 2006 - IPC G01F23/30 G01N9/10 

FIELD: instrument engineering.

SUBSTANCE: device can be used for measuring density and level of liquid in closed rooms. Device has float made in form of hollow cylinder which has lower end to be air-tight closed; protecting pipe with holes in top and lower ends; float disposed inside the pipe; strain gauge converter, flexible rope connected with float and strain gauge converter; microcontroller provided with analog-to-digital converter which is connected with output of strain gauge converter. Device also has stepping reversing motor with micrometer screw fastened to shaft of the stepping motor, bracket with guide lath which is mounted in top end of pipe. Micrometer screw is connected with strain gauge converter, which is mounted onto guide lath for vertical movement.

EFFECT: widened functional capabilities.
