Water level measurement
Seifert, Jiří ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
This thesis is dealt with measurement of water level. Measurement is palced in the concrete container under the ground. It was choosen an ultrasonic sensor as an optimal result. The sensor is placed in the safety container IP 65 and it is placed outside into container. The part of water level measurement is the system of the autocalibration. The signal of the sensor is evaluated by ARM microcontroler ESP8266EX. Calculated water level is broadcasted by WiFi modul to server.

Contactless level measurement
Pribula, Wojciech ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
The~thesis begins with an~analysis of~methods of~water level measurement in~high-pressure system. This~systems are placed in~heating plants and power plants and they work with the water whose temperature exceeds 300\,°C and whose pressure is above 10\,MPa. Thesis present method of~differential pressure with the~derivation of~the~correction element and also is~described capacitive method, especially Hydrastep system. This~work prepares theoretical foundation under creating algorithm for level detection using image recognition. Also it considers suitable hardware as~camera and light for illuminating and highlighting the~level. It~includes outline of~captured image editing and detection algorithm. The next part of thesis is dedicated algorithm itself. There are described classes and methods that are used for level detection or for debugging. Also, there are specified necessary modifications of watermark and requirements for watermarks surroundings thats are necessary for proper functioning of the algorithm.

Level indikator with wireless communication
Smatana, Tomáš ; Friedl, Martin (referee) ; Szabó, Zoltán (advisor)
This thesis describes the design and realization of a device that is used for wireless measurement and control of liquid level. The first section explains the different options for level measurement, different implementation of wireless communication and describes the basic features of the Atmel AVR microcontrollers. Based on this analysis, appropriate solutions are selected sensors and wireless modules suitable for the design of the device. The second part is the design of a device which is subsequently implemented.

Measurement of Level by Fiber Optic Sensors
Bednář, Tomáš ; Havránek, Zdeněk (referee) ; Šedivá, Soňa (advisor)
The subject of this master‘s thesis is the issue of design of fiber optic sensor for min/max and continuous measurement of liquid level, which could be used for laboratory measurement of optoelectronics. The thesis is divided into the three parts, the first part deals with methods of retrieval level measurement using fiber optic sensors. The second part is made of plant design of optical fiber sensors, it is shown the implementation of measuring devices for liquid level measurement and measured transfer characteristics of the sensors developed. The last part is proposed for laboratory typing tasks using established preparation for teaching in the subject Optoelectronic sensors.
