FIELD: measurement technology and instrumentation engineering.
SUBSTANCE: proposed inclinometer has cylindrical vessel filled with working fluid, two light sources located beyond fluid and optically aligned, two photocurrent amplifiers connected to outputs of photodetectors, recorder, microprocessor and four light conduits. Microprocessor inputs are connected to amplifier outputs and its output is connected with recorder. Light conduits are wound in form of fiber coils and are optically connected with light source and photodetector in two interferometers. Light source is coherent. Fiber coils are located in pairs on bottom of working fluid vessel in diametrically opposite position. Recorder is made in form of frequency meter.
EFFECT: avoidance of effect of amplitude factors on results of measurements.
