Development of an ultrasonic fourteen channel flowmeter for visualization of the flow profile

The problem with existing flow meters is a relatively high measurement error, which is associated with a lack of information on the flow profile. In order to create a reference device that makes it possible to study the flow profile due to a larger number of sensors, with bore size 50 mm primary transducer with fourteen channels is developing and manufacturing. This device can provide more accurate results due to the use of multiple channels of ultrasonic signal passage, which makes it possible to calculate large time points along the entire section of the pipe, as well as the ability to visualize the flow profile. In the course of the work, a 3D model of the primary transducer was developed in accordance with the requirements and conditions for the passage of ultrasound through a liquid medium, when it was necessary to take into account the simultaneous operation of several channels at once, taking into account the fact that the paths of ultrasound passage should not intersect. Processing several signals at once becomes possible, since five TDC microcontrollers will be used for all channels.
