ELECTRIC DEVICE MEASURING DENSITY OF LIQUID IN WATER TUNNEL WITH USE OF TEMPERATURE-SENSITIVE RESISTORS Russian patent published in 1999 - IPC

FIELD: aviation industry. SUBSTANCE: invention can be used to study various flying vehicles in water tunnels or in other branches of economy where study of turbulent flow of liquid is necessary. Electric device incorporates generator of master frequency pulses, frequency divider, counter of controlling pulse, multiplexer of longitudinal contacts connecting temperature-sensitive resistors, multiplexer of lateral contacts connecting other lead-out of temperature-sensitive resistors, matching unit, analog-to-digital converter, indicator, water tunnel, object to be blown against, lattice with temperature- sensitive element. EFFECT: generation of objective picture of distribution of pressure of liquids passing over object blown against. 2 dwg
