AF1 Series Flow Sensor
Compressed air
consumption/time
Avoid energy losses and save money
by continuously monitoring the air consumption
in your system
Greater energy efficiency with AF1
AF1 series flow sensors constantly compare the actual
values in a system with the set process values, allowing

you to reliably control flow rates and detect larger leaks.
A high degree of overall cost control is provided through the
Activated
system lock
allocation of costs to specific products. The flow rates are
determined by the AF1 sensor module using the difference

in pressure between the two internal measuring points and

for the display. The AF1 has two PNP/NPN switch outputs
and one analog output. Users can set switching points

for the two switch outputs on the basis of flow rate, air
consumption, or pressure. The analog output provides the
