The FlexFlow flow sensor measures the flow velocity of aqueous media such as CIP cleaning agents and beverages. It operates according to the calorimetric measuring principle. In addition to monitoring the flow velocity, this also makes it possible to determine the media temperature.
The calorimetric measurement principle is based on the physical laws of thermal conduction and thermal transfer in liquids and gases. A body with a higher temperature releases energy into its environment in the form of heat. The amount of this energy release depends on the temperature difference and the mass flow rate. This can be used in measuring technology: a heated sensor is cooled by the liquid flowing around it, and the degree of cooling is directly dependent on the mass flowing past it. In addition to the flow rate, the media temperature can also be recorded and monitored with one sensor.
Get to learn with Mr. Martin Leupold, Senior Product Manager Process Sensors, how the calorimetric measuring principle works and see for yourself how efficient and flexible fluid management can be using the flow and temperature sensors FlexFlow.
