Active signal
The F012-P is suitable for flowmeters with an Active signal output. With an input impedance of
47kΩ, the detection level is about 1.2V. See
SETUP
5.1: FLOWMETER > SIGNAL[»16] for more information.
Active signal selection is often used in combination with the sensor supply output offered with type
PD.
