FLUID PHYSICAL PROPERTIES METRE

摘要

FIELD: physics.;SUBSTANCE: proposed device comprises metal cylinder arranged in controlled fluid flow to accommodate internal U-shape conductor with generator connected thereto to excite oscillations in aforesaid cylinder, and unit to measure resonance frequency of aforesaid cylinder. Note here that frequency-modulated oscillation generator is connected to one end of said cylinder via high-frequency transformer, while resonance frequency metre is connected to opposite end of said cylinder via second HF transformer.;EFFECT: measurements may be made in removing electronic unit from object to be measured, reduced influence of cable parametres on measurement error.;1 dwg
