Version With Pulse Output - Burkert 8012 Manuel D'utilisation

Generalinformation
Depending on the version, the electrical connection is made using a
1 m long cable or a multi-pin M12 fixed connector which position can
be adjusted.
Depending on the version, the device is equipped:
• with one pulse output
• or one pulse output and one 4-20 mA current output.

Version with pulse output

On the 16 basic versions of the SE12 module (see chap. 5.5), the
NPN pulse output generates a signal with a frequency f proportional
to the rotation frequency of the paddle-wheel.
To obtain a flow rate Q, this frequency must be divided by a propor-
tionality factor K according to the following formula:

Location of the LEDs
(depending on the version)
Q = f/K
