In a number of technological processes, it is very important to control the flow of media in the pipeline without having to accurately measure the flow of information (cooling circuits, empty pumps, batch run, etc.). For such purposes, flow controllers are preferably applied. In principle, all of our meters can be used for this purpose as flow rate monitors, and the whole range of our induction and blade flow meters is also available.
In general, the principles of flow watches can be divided into mechanical and electronic. For mechanical guards, it is often a matter of destroying the resilient element (paddle switches) to ensure the proper operation of the guard, even after a short interval of use. In the case of an electronic guard, this is a calorimetric principle without any mechanical elements, and thus with a much lower susceptibility to the actual destruction of these watchers and with a very long life. A great advantage is the precise setting of the switching point by the learning system.
