FIELD: instrument engineering. ^ SUBSTANCE: device has level measuring float disposed in vertical inside holed pipe, converting member, temperature detector, and measurement unit. Device also has hollow washer provided with bridge which washer is connected with protection pipe, density-measuring float mounted at lower end of level measuring float for vertical movement, and system for displacement of density-measuring float. Level-measuring float is made in form of tube. Converting member is made in form of resistance strain gauge conjugated with level-measuring float. Measurement unit is made in form of control microcontroller. System for displacing level-measuring float is made in form of ferromagnetic disc fastened to density-measuring float and to solenoid connected with output of control microcontroller. ^ EFFECT: simplified design; improved efficiency of measurement. ^ 1 dwg |
