Анотация: Liquid level measurement in todayТs industrial environment encompasses a wide variety of needs and applications. To meet this wide array of needs the process controls industry has developed a planty of sensors and devices to handle this demand. Water measurement is a very critical and widely measured variable for most automation engineers due to guarantee safty of people in the industry and safe as much as possible electrical power. Many processes in the industries must have either a monitored or a controlled liquid level. In this paper a water level control and monitoring solution is used, based on the microcontroller СNodemcu ESP8266Т ( it has its own wifi module ) and the NodeRed platform
