Annotation. The goal of the this research is to analyze of currently used liquid level meters in steam boilers, determine their strengths and weaknesses, as well as search and offer new types of liquid level meters suitable for use in steam boilers.
This article looks for the differences between the various types of meters such as hydrostatic, capacitive, magnetostrictive, bypass. It’s considers advantages and weakness for measuring the liquid level when used in steam boilers. The basic requirements for liquid level meters for use in steam boilers have been determined. Also there were considered the principle of operation of a potentiometric level meter and the influence of environmental parameters on its measurement. Based on the generalization of obtained information, a new type of liquid level meter has been offered that patented in 2019 year and meets the necessary requirements, and was offered a specific model of the meter produced by the industry.

Key words: steam boiler, steam, water, heat, pressure, temperature, energy, liquid level meter, potentiometric method.
