ABSTRACT:
A heat meter for measuring the rate of flow or quantity of flow of heat gained or lost by a flowing and confined heat transporting medium between two monitoring points comprises inlet and outlet conduits for the passage of heat transporting medium, one conduit having mounted therein a temperature sensitive unit for monitoring the temperature of the flowing medium and therebeing associated with an insulated section of the other conduit a heat transfer unit to heat the medium passing therethrough and a temperature sensitive device for monitoring the temperature of a region of the heat transfer unit which, in use, is in thermal contact with the heat transporting medium, and a controller arranged so that the difference between the two monitored temperatures is minimized.
