A METHOD FOR MONITORING A FLOW CONDITION, A LEAK INDICATOR AND A LOW HEAT EXCHANGE INDICATOR, BOTH TO BE USED BY THE METHOD

摘要

The invention relates to a method of automatic monitoring a flow condition and to indicators to be used by the method. A method is intended for indicating a possible leak in a cold water supply pipe and a method is intended for indicating a possible low heat exchange in a domestic heat exchanger. The methods use measurements of temperatures on the surface of a pipe and measurements of temperatures of the surroundings or of another pipe. The leak indicator monitors a temperature difference between the surface of the cold water supply pipe and the temperature of the surroundings, and the low heat exchange indicator monitors a temperature difference between the surface of an inlet pipe and the surface of an outlet pipe of the heat exchanger.
