Abstract

A system and method for measuring mass flow of a non-gaseous phase of material such as a solid particulate are described. The material flows through a conduit of which a section is heated or cooled. One temperature sensor is provided upstream of this section and at least another temperature sensor is provided downstream of it. These temperature sensors are adapted to measure the temperature of material in the non-gaseous phase directly. The section is heated or cooled for a first period of time and then neither heated not cooled for a second period. A third temperature sensor is provided in good thermal contact with the heated or cooled section – this temperature sensor. The temperature sensors measure the temperature of the non-gaseous phase of the material flowing in the conduit in at least the second period of time. The mass flow of the non-gaseous phase of the material is calculated from the measurements of temperature.
