Process monitoring entails systematic recording or measurement of an operation or process by means of technical aids. Repeated, regular execution is a central element of that activity. Statistical process control and management help to optimize and stabilize processes. They also ensure appropriate monitoring of threshold values. Ultrasound-based clamp-on flow meters are ideal measuring methods for that purpose because they enable data collection without requiring operators or equipment to intervene in a process. Noncontact flow sensors also combine high precision with…
