摘要： A device for monitoring heat transfer systems. A non-heated temperature sensor is used to determine the approximate temperature of a flowing fluid being monitored. A heated temperature sensor is exposed to and is thereby cooled by the flowing fluid being monitored. A flow measurement is made using a flow sensor and the heat transfer from the heated temperature sensor to the flowing fluid is determined. An electrolytic means is provided for chemically altering the environment of the heat transfer surface of the heated temperature sensor to determine its use or effects for testing, operation and maintenance of the heat transfer system and also the device. A hot tap insertion flow probe configuration is presented which includes a cost effective miniature magnetic flow sensor using permanent magnets.

摘要： An electro-mechanical, dual tube and plug device for on-line monitoring of performance losses due to reduced conductivity of a heat exchanger resulting from micro-bio fouling of the surfaces of said heat exchanger/condenser and for detecting change of heat transfer resistance of individual heat transfer tubes. The dual tube and plug assembly includes a first flow assembly tube and a second temperature assembly tube attached to the discharge end of a heat exchanger for providing accurate measurement of temperature and cooling water flow. The first flow assembly tube includes a tube having an inner chamber, including a flow sensor comprising a paddle wheel and a sensor and a temperature sensor for measuring discharge water temperature. The second temperature assembly tube plugs the inlet and the outlet of a heat transfer tube immediately adjacent to the flow assembly tube and includes a plurality of spring loaded temperature sensors in the plugged empty heat transfer tube. Flow and discharge temperature signals from a first dual tube device are combined with other flow and discharge temperature signals, from additional dual tube devices. These signals are sent to a micro-processor which, utilizing inlet water temperature data provided by an inlet temperature sensor, continuously calculates, records and displays the individual heat transfer tube heat transfer co-efficient.
