Development of cylindrical hot-film sensors for measuring instant velocity of fluid flow

Concentration measurement with thermal probe for pulverized coal in the pneumatic pipeline of power plant

“…The thermal probe behaves like a hot film with little heat power needed. As well known, the hot film anemometer detects gas velocity based on the trace amount of thermal loss due to the convective heat transfer between gas and hot film [21]. Similarly, the thermal probe detects solid concentration based on the little amount of thermal loss between gas-solid flow and thermal probe.…”
