Reliable Detection of Flow Limit Values

摘要

In many cases air or volume flow is process and quality related. Common flowo flow-information is mostly insufficient. In demanding applications the Schmidt Flow Sensor SS 20.200 will supply a precise switching signal to defined threshold values - independent of the medium temperature. For many applications, i.e. ambient air technical equipment in buildings, cleanroom technology, ventilation/exhaust systems and manufacturing processes, air and volume flow must be controlled. In most cases the plant operator only needs to know if the flow values are outside defined parameters. There are similar requirements for compressed air equipment where defined flow values must be maintained or for minimum flow rates in drying processes. In many cases the detection of air and volume flow is also required for equipment protection such as the control of supply air in cooling systems or filter monitoring.
