Abstract
Energy loss from hot or cold piping and process equipment can be measured with good reliability using heat flux transducers and careful monitoring techniques. Two types of industrial instruments are discussed in the paper -- one that wraps externally around pipe and one that can slip within and beyond the overlap of a pipe jacket procedures for using these instruments are being balloted within ASTM committees. Such transducers I can be used to measure energy loss, control process parameters and follow changes off ambient weather conditions for indoor, outdoor, buried and downhole applications. A variation of this instrument can be placed on columns under insulation to act as control sensor for adiabatic operation.
