1 SAFETY RECOMMENDATIONS

Always respect the safety instructions marked by the symbol

opposite as well as those included in the manual.

1.1 Utilisation

The 8030 sensor is designed for measuring the flow of neutral or slightly

aggressive solid free liquids.

There will be no manufacturer warranty for damages caused by

unexpected handling or wrong usage of the device.The warranty on the

device becomes invalid if any modification or change is made on the

device.

The device should only be installed and repaired by specialist

staff. If any difficulties may occur with the product during

installation, please contact your nearest Bürkert sales office for

assistance.

ENGLISH

1.2 Precautions at installation and commissioning

- Always ensure the materials in contact with the medium to measure are

chemically compatible with this medium.

- To clean the device, only use chemically compatible products.

- Protect the sensor from electromagnetic perturbations, the rain and

ultraviolet radiations.

When dismounting the sensor from the pipe, take all the

necessary precautions linked to the process.

1.3 Conformity to standards

EMC: EN 50081-1, 61000-6-2

ENGLISH

Flow sensor 8030

2.1 Design and measuring principle

The 8030 flow sensor is made up of an SE30 electronic module and an

S030 fitting with integrated paddle-wheel.

The sensor detects the rotation of the paddle-wheel which generates a

signal whose frequency f is proportional to the flow rate Q, according to

the following formula:

f = K.Q

f = frequency in Hertz (Hz)

K = K factor specific to each S030 fitting, in pulse/litre

Q = flow rate in litre/second

Order code table for SE30 electronic modules

Following versions of the electronic module are available:

- either with 2 pulse outputs (Hall effect sensor with 2 transistor outputs,

NPN and PNP),

- either with 1 sinus output (coil)

- either with 1 pulse output (Low Power Hall effect sensor with 1 NPN

transistor output).

The electrical connection is carried out via a cable plug

EN 175301-803 (type 2508).
