description: This work is about the development and creation of a heat transfer monitoring system for saturated steam condensation on the vertical pipe. The study feature is the use of an integrated approach that combines the 5 most common methods for studying film condensation: - the average heat flux per unit area calculation by the cooling water heating (method 1); - the average heat flux per unit area calculation by the condensate flow rate measurement (method 2); - the visual observation of condensation (method 3); - the calculation of local heat flux per unit area according to the equation of steady heat conduction through the pipe wall (method 4); - the measurement of local heat flux per unit area by using gradient heatmetry (method 5). As the result, the advantages and disadvantages of using experimental approaches were determined. The integral approaches low informativeness (methods 1 and 2) was revealed. The flow visualization (method 3) made it possible to determine the regime and features of the condensate flow but is not applicable in an industrial experiment. The method 4 is applicable for heat transfer monitoring during stationary condensation, but is not useful in non-stationary conditions. The gradient heatmetry applicability (method 5) to the monitoring of heat transfer during condensation is revealed. As work result, an integrated heat transfer monitoring system for saturated steam condensation was created.
