MAIN CHARACTERISTICS OF THE HEAT FLOW METER

Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The problems and prospects of application of non-destructive testing methods for technical diagnostics of the thermal networks state and various technological objects are discussed. The recording of the temperature state of thermal processes by using a flow meter is due to its sensitivity to the change of thermophysical characteristics and the ability to control without the use of an external energy source, etc. The description of the developed device to measuring of the heat flow using of a thermoelectric heat flow converter of a special design is shown. A distinctive feature of the device is the heating element that installed on an insulating layer serving as a support surface. Calibration of the device is proposed to be carried out by replacing the heat flow from the investigated object with the heat flow released in the heating element when an electric current passes through it. The developed device can register the changes in the heat flux density in the range of (25-100) W/m2, which allows it possible to detect the smallest thermal insulation defects.
