Currently, the shortage of water in our country is growing. This means that we must support every drop of water. At the same time, water management systems in advanced economies are used to measure and monitor water flow and water meters with different designs. Existing measurement and control systems have some drawbacks in energy saving. Therefore, the issue of improving water and energy saving water flow devices and rights management levels was considered.

Currently, we live in a world where all fields are developing very rapidly. In particular, the field of water management is developing day by day, and the water supply system is being intelligent automated. Nevertheless, mechanical means and human labor are used to monitor the water level in many water management facilities of our region. This situation causes many problems in the automatic management of the system. In this article, we will consider the process of automating the measurement and control of water level, that is, an automated system that helps to know when the water in the tank is full or empty. In the automation of this system, an ultrasonic sensor that meets the requirements of the time was used. The working principle of ultrasonic sensors is based on the movement of ultrasonic waves over time. The analysis of the results of this experiment showed that the water level measurement and control system did not make more than 1.5% error in different values of the water level. This situation showed that the developed system can be effectively used in all water level control facilities.

The city of Tashkent is developing at a very fast pace, and the power supply of a new type is the subject of innovation in this direction. Commercial metering of electricity in multi-storey buildings in modern cities mainly solves the current payment problems for consumed electricity. And the main disadvantages of such networks will remain overboard. Technically competently control the common highway of a multi-storey building is necessary. Here, the commercial metering of electricity consumption does not solve the technical policy considering the development of the city. The construction of multi-storey buildings based on an individual project is growing rapidly in the city. Together with the environmental aspects of the impact of such buildings, it is necessary to address the issue of reliability in power supply. The use of power supply schemes taking into account backup power is relevant. It is proposed to take a diesel power plant as a backup source. For this, an electrical circuit of relay protection using an automatic transfer switch is proposed.
