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
PM and type PF.

Reed switch
The F012-P is suitable for use with flowmeters with a reed switch. To avoid pulse bounce from the
reed switch, it is advised to select REED LP - low-pass filter (
