Introduction
Electronic flow monitors operate on the basis of the calorimetric principle. They use the physical effect that a flowing medium absorbs heat energy and conducts it away. The sensor tip contains two temperature-dependent resistors as well as a heat source. The heat source generates a local temperature rise in the medium which is detected by one of the PTCs. If the medium flows, energy is conducted away from the heat source, i.e. it is cooled. The resulting temperature change is an indication of flow. To avoid a falsification of the result of the measurement by a change in the medium temperature, a second PTC is used for temperature compensation. As these systems work without any mechanically moved parts the user can mount them independent of mounting position and flow direction. For certain applications and environments preferred positions are recommended.
ifm electronic
ifm electronic gmbh is one of the leading manufacturers of automation technology world-wide. More than 3,000 employees in more than 70 countries develop solutions for 80,000 customers in the manufacturing industries. By optimising technical processes in the automotive, chemical and cosmetics industries or in environmental technology and automation of buildings ifm electronic has consistently set new standards and thus ensures tomorrow's production processes.

The family-run company with headquarters in Essen started with the invention of inductive proximity sensors in 1969. The German production in Tettnang on Lake Constance has ensured brand quality right from the start. Today "efector" stands for position and fluid sensors, object recognition, diagnostic and identification systems. The brand "ecomat" is synonymous with networking and control systems. In 2007 ifm made a turnover of more than € 410 million with above-average product quality, exceptional innovations and consistent close contact to the customer.
