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:
Extremely communicative: all measurement data is transmitted to the controller via the IO-Link® communication interface. The benefits to you: data storage, remote parameterisation and reduced wiring. PNP or NPN? NO or NC? 0 ... 10 V, 1 ... 5 V or 4 ... 20 mA? The SFAB can do everything in one device. The electrical outputs can be switched between PNP and NPN using software. This also facilitates warehousing, reduces costs and provides more flexibility. For fast and reliable commissioning, all settings made on one sensor can be replicated, i.e. they can be transferred to other identical sensors within seconds. This process is much less prone to errors than manual commissioning.
Easy to operate: the new design with larger pushbuttons, intuitive menu navigation and a clear display enables reliable and straightforward operation. The SFAB reliably measures flow rate and volume and records the temperature. Energy consumption can be optimised because you can, for instance, quickly detect a leakage. It is reliable even when a higher protection class and precision are required, for example for paint spray guns in the automotive industry. And its ability to detect the temperature allows you to control and stabilise processes. As deviating temperatures can indicate a components is defective, for example.
The SFAH monitors the flow rate of compressed air and non-corrosive gases. Many industry sectors will appreciate the flexibility it offers in terms of its compact design, numerous installation options and space-saving adjustable QS elbow connections. The bypass construction of the SFAH means that it is less susceptible to particles and moisture. The flow rate value is transmitted to the connected controller as a switching signal, an analogue signal or via IO-Link®.
Wide application area with 8 flow rate ranges from 0.002 l/min ... 200 l/min mean the highly precise SFAH is very flexible. Whether used for process monitoring, feedback when handling small parts, consumption monitoring, leak tests, forming gas monitoring or object monitoring via air gap measurement, the SFAH handles all tasks with ease.
Quick installation, simple operation: The SFAH does not require any laminar flow inlets. The QS plug-in connections and the L1 and M8 plugs ensure that the SFAH can be put into operation quickly. Navigating through the menus on the clear display is highly intuitive and users can configure the colour scheme of the entire display.
