DEVICE FOR MEASURING ANGLE OF INCLINATION PLANE Russian patent published in 2016 - IPC G01C9/22 

FIELD: measuring equipment.

SUBSTANCE: device relates to measurement equipment and can be used in geodesy; at construction of extended hydraulic structures; at creation of instruments and devices which require referencing to the horizon; as well as in physical experiment. Device for measuring angle of inclination plane comprises two liquid capacitor placed in vessels of dielectric material. Vessels are installed on a common substrate and are interconnected by means of connecting tube. Inductances of fixed value are connected to top plates of capacitors. Inductance and capacitance of capacitor in each vessel forms a resonant LC circuit which is connected to the setting input of the self-contained generator. Frequency of self-contained generator is measured simultaneously with the help of device. Operation of the device is based on determination of height of liquid column in two liquid capacitors placed in the communicating vessels, frequency oscillator, which can be measured with high accuracy. By measured values of frequencies inclination angle is calculated using corresponding formulae. Thermal effect on accuracy of measuring the angle of inclination plane is corrected based on the known dependence of structural elements and fluid parameters on temperature.

EFFECT: technical result consists in improvement of accuracy of measuring angle of inclination.
