FIELD: instrument-making industry, possible use for measuring level and density of liquid in closed volumes. ^ SUBSTANCE: device has perforated pipe, inside which float is positioned, measuring block and temperature indicator. System for moving the float is made in form of stepping reversing electric engine, drum with cable, connected to float, and guiding roller, mounted on tension transformer. Measuring block is made in form of controlling microcontroller, first input of which is connected to output of tension transformer, second output - to output of temperature indicator, and output - to input of reversing step electric engine. ^ EFFECT: improved precision, reliability and expanded measuring range. ^ 1 dwg |
