Background. Level gauges signaling devices have wide scope of application: they are used in the fleet and shipbuilding, in food, chemical and pharmaceutical productions, in oil and gas, fuel, rocket and technical and other industries. Development of science and technology goes on the way of active introduction of safe and reliable measuring devices on the basis of use of breakthrough technologies. Objective of this research is creation of new designs of the level gage pressure indicator of the liquid environments adapted for specific conditions of operation on the basis of properties of fiber optics for creation of explosion-proof measuring devices.
Мethods. When developing a design of the fiberoptical sensor level gage bases of circuitry design of measuring devices, methods of geometrical and fiber optics are used.
Results. Models and designs of the fiber-optical level gage pressure indicator which distinctive feature is simplicity and reliability of a design, accuracy of measurement of level or hydrostatic pressure of any type of liquid in the required points of capacities due to introduction of the elastic element separating the sensitive element from liquid which is hermetically connected from one end face to the case are developed.
Conclusions. New technical solutions of level gages pressure indicators, on the basis of the fiber-optical principle of action will allow to provide safe, exact and reliable measurement of level of types of liquids and also their hydrostatic pressure in different service conditions.
