6.3. Mounting options

The modular concept of the Type SE12 electronic module allows fully customized, pre-mounted and tested solutions to completely meet

application needs. The electronic module is designed for being mounted in a system block, combined with other Bürkert products. This

allows cost reduction and compact design for customized solutions.

Product operation

7.1. Measuring principle

The Type SE12 electronic module is equipped with two LED indicators, visible, due to transparency nature of material, under the male

connector (standard) or on the side opposite the male connector (on request).

Location of the LEDs

When the power is turned on, the green LED lights up and flashes proportionally to the paddle wheel rotation frequency. The lighting up of

the red indicator LED indicates a malfunction of the device. When liquid flows into the pipe, the paddle wheel is rotated. The non-wetted

permanent magnets inserted in the paddle wheel generate a measuring signal whose frequency is proportional to the flow velocity. With the

optical method, the same procedure is used, but the light beam is interrupted.

Two electronic module variants allow the following outputs:

• With one pulse output (either NPN or PNP transistor output, configurable).

An external power supply of 12…36 V DC is required. This pulse output generates a signal whose frequency is proportional to the flow

velocity. It is designed for connection to any system with open collector NPN or PNP frequency input.

• With one 4…20 mA current output and one pulse output (either NPN or PNP transistor output, configurable).

An external power supply of 12…36 V DC is required. The 4…20 mA output delivers a current whose value is the image of the flow

velocity.

The output signal is provided via a free positionable male 5-pin M12 male connector (or a cable gland with 1 m length cable on request).
