This article discusses ultrasonic sensors for level monitoring and measurement, with unified 4... 20 mA output current signals, with two-wire digital industrial communication interfaces such as HART, PROFIBUSSPA and Foundation Fieldbus. [1.10] The most widely used ultrasonic sensors of the LUC4 and LUC-T series and methods for installing and connecting ultrasonic sensors of the LUC-T series are presented. The principle of the implementation of the ultrasonic method for determining the water level is also presented here. This measurement method guarantees reliable operation of ultrasonic sensors in various conditions. [2.5.11]. The advantages and disadvantages of the ultrasonic measurement method are shown. To implement the method, it does not impose high requirements on the wear resistance and strength of the equipment and is independent of the density of the controlled medium. [3.12] The sensor has a built-in compensation system from the influence of temperature fluctuations on the measurement result. [4.13] Sensors of the LUC4, LUC-T series are specially designed and operate on a non-contact measurement method and measure the level of water and various liquids. [5.20]
