Tests of liquid dispensers intended for hydraulic systems with advanced diagnostics

Abstract

The basic function of the liquid level indicator is to visualize the liquid level in a closed container. As the techniques of automatic regulation, diagnostics, and intelligent protection have developed liquid level indicators to meet more and more functions, thanks to builtin measurement systems or the identification of limit values of selected parameters of liquid contained in the tank. Concentration of several variant functions in one element with parameterized, fixed building conditions is beneficial mainly due to the possibility of the simplification and standardization of the construction of tanks and hydraulic installations. The work describes the course and results of research and development works, the effect of which is the development and implementation of further solutions that make up the series of multifunction liquid level gauges designed for advanced power hydraulic systems. The task of the authors was to develop the construction, manufacturing technology, and the operation of electrical signalling systems and to conduct leak tests.
