FIELD: pressure measuring equipment, particularly to measure small pressure change under temperature perturbation.
SUBSTANCE: manometer comprises U-shaped pipe with optically transparent caps and measuring indicator made as laser interferometer. The pipe is filled with liquid. Laser interferometer is created of semi-transparent mirror, semi-transparent mirror, totally reflecting mirror, photodetector and signal processing unit. The mirrors are installed on U-shaped pipe projection axes and are inclined at 45° to laser axis.
EFFECT: increased measuring accuracy.
