polarity reversal

yes

Protection against

spike voltages

yes

Protection against

short circuits

yes, for the pulse outputs

Pulse output

• Version with 1

pulse output

• Version with 2

pulse outputs, NPN

and PNP

transistor

• open collector, 20 mA max., NPN output:

0,2-24 V DC, frequency up to 300 Hz

(frequency = K factor x flow rate).

• open collector, 700 mA max., frequency

up to 300 Hz (frequency = K factor x

flow rate), NPN output: 0,2-36 V DC and

PNP output: Supply voltage

6.3.4. Electrical connections

Version Type

With a cable gland Cable, 1 m

With a fixed connector Male 5-pin M12 fixed connector

6.3.5. K factors

The K factors have all been determined in the following reference

conditions:

medium = water, water and ambient temperatures 20 °C, min. upstream

and downstream distances respected, appropriate pipe dimensions

Two versions of the S012 in DN15 and DN20 exist, having

different K factors.

Only version 2, identified by the "v2" marking, is available

from March 2012. The "v2" marking can be found:

• on the bottom of the DN15 or DN20 fitting in plastic:

• on the side of the DN15 or DN20 fitting in metal:
