Flow sensors

Flow sensors measure the flow rate of liquid or gaseous media. They are used to monitor the volume or mass flow rate of a medium through a control system. By observing the flow rate, simple diagnostic and condition monitoring tasks can be carried out; after all, a change in the flow rate is often an indication that problems are likely to occur. Simple transmitters, so-called flow transmitters, output the physical measured variable as an electrical signal. The majority of flow sensors offer digital switching outputs or even digital and analogue outputs.

Flow sensors are ideal for flow measurement in the following applications:

• Flow rate and air consumption measurement for evaluating energy efficiency
• Leakage monitoring
• Sensing for picking up very small parts (very small suction cups))
• Presence monitoring
• Leak tightness testing
