“…Capacitors with a small value filter out highfrequency noise, and capacitors with a large value filter out low-frequency noise. Usually there are ceramic capacitors with a capacity of 1 pF  0,1 µF and their voltage is around 16-50 V [16].…”

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.

“…It is known that capacitive sensors can be used in measuring the absorption coefficient of insulating materials of transformers, linear and angular displacement transducers of contact network installations using various bridge balanced transducers, including four-arm auto-compensation, in the circuits of which transformers with close inductive coupling and operational amplifiers with deep feedback in alternating current are used [2,7].…”

The article discusses the principles of operation of quasi-balanced bridge converters with closely inductive couplings between the arms, having an extended range and maximum sensitivity by creating a parametric auto-resonant mode by changing the supply frequency of the measuring bridge. To reduce the errors of the conversion elements, a conversion algorithm based on a mathematical model is proposed, and a schematic diagram of a capacitive sensor parameter into code using a microcontroller is given.
