Abstract
Thermal mass flow meters can, in theory, be used in pneumatic conveying applications to provide a reliable monitoring of the mass flow rate of solids being transported in a stream of gas. Accurate measurement of temperature is necessary for the mass flow rate to be reliably determined. Direct measurement of temperature of particulate solids being conveyed pneumatically can be achieved, in principle, with the use of intra-red (IR) detectors. This has been done in previous work for the measurement of solids’ temperature in a pneumatic conveying line where windows were employed. This paper investigates the influence of windows on the temperature measurement process.
