DEVICE FOR MEASURING OF LIQUID LEVEL IN RESERVOIR |
摘要 |
FIELD: checking of fuel level in reservoirs. SUBSTANCE: device has laser, photoreceiver and laser beam focusing element made in the form of lens positioned between laser and surface of liquid. Relation between lens focal distance F<SB>l</SB> and minimum distance h<SB>min</SB> from lend to liquid surface is within F<SB>l</SB>/h<SB>min</SB> = 0.1-0.2. EFFECT: enhanced accuracy of measurement, simplified construction. 4 cl, 4 dwg
