FIELD: heat exchange.
SUBSTANCE: invention can be used for control of technical condition of heat exchanger. Essence of the invention consists in the fact that at least one of the heat transfer tubes is fitted with an ultrasonic sensor configured to operate at an operating pressure of more than 30 bar and/or an operating temperature of more than 80 °C, wherein wall thickness of appropriate heat transfer tube is determined by appropriate ultrasonic transducer at its place of operation, wherein measurement data from appropriate ultrasonic transducer are transmitted to electronic data acquisition unit during heat exchanger operation.
EFFECT: providing the possibility of determining thickness of walls of heat exchanger tubes during its operation.
