Turck India Automation Pvt. Ltd. Manufactures Flow Sensors for Wear-Free Flow of Liquid Media. Turck India Automation Pvt. Ltd. Manufactures Industrial Automation, Electronic Components, Sensors, Interfaces, and Fieldbuses. The Flow Sensors for Wear-Free Flow of Liquid Media is based on the heat transport/heat loss principle, i.E., when fluid moves over the heated sensing probe, heat is conducted away from the sensor. The heat loss is thus a measure of the flow speed. The Flow Sensors monitor reliably and wear-free the flow of gaseous and liquid media.
