2.1 Device description

The electromagnetic flowmeter BATCHFLUX 3200 C is designed exclusively for measuring the

volumetric flowrate of electrically conductive non-flammable liquids. The typical installation is

within the cabinet of an Ad Blue filling station. The equipment consists of a measuring tube with

the process connections, an inner plastic housing where the complete electronic is placed and

an outer stainless steel cover housing for protection purpose. The inner plastic housing with the

electronics and the magnetic coils included is completely encapsulated. The electrical

connections are made via a permanently connected cable.

The installation is within a Zone 1 classified hazardous area, considering a non-hazardous area

within the measuring tube. The equipment is powered with 24 VDC, a RS485 interface is provided

for communication with a control unit.

2.2 Marking

The marking of the entire device is clearly visible on the stainless steel housing.

2.6 Electrical data

The 24 VDC power supply circuit, the RS485 interface and the earth potential (housing) are

galvanically conneted within the electromagnetic flowmeter.

For both circuits the 24 VDC power supply and the RS485 interface a safety separation from

hazardous voltage is required (SELV / PELV).

The equipment may only be connected by means of the permanently connected cable.

3INSTALLATION

BATCHFLUX 3200 C

www.krohne.com 08/2016 - 4005430201 - MA_Ex_AD_BATCHFLUX 3200 C-

3.1 Installation

Installation and setup must be carried out according to the applicable installation standards (e.g.

IEC 60079-14) by qualified personnel trained in explosion protection. The information given in the

Installation and Operation Instructions and the Supplementary Installation and Operation

Instructions must always be observed.

Electromagnetic flowmeters must be installed in such a way that

•There is no danger from mechanical impact effects.

•There are no external forces affecting the equipment.

•The equipment is accessible for any visual inspections that are necessary, and can be viewed

from all sides.

•The data plate is clearly visible.

•The equipment is protected against UV-light.

CAUTION!

The manufacturer is not liable for any damage resulting from improper use or use other than the

intended purpose. This applies in particular to hazards due to insufficient corrosion resistance

and suitability of the materials in contact with the product.

DANGER!

The optional connector at the connection side of the cable shall be connected outside the

hazardous area.

4.1 General notes

The circuits are not galvanically isolated from ground (housing).

The connecting cable is in conformity with the applicable installation standard EN 60079-14. The

temperature rating of the cable is equal to or better than -40 ... +90 °C.

•The connecting cable must be fixed and laid so it is sufficiently protected against damage.

•The shield must be carefully insulated against each core and against ground (test voltage t

500 V

eff

) at the connection side.

4.2 Power supply

The electromagnetic flowmeter does require a power supply unit complying with standards for a

safety separation from hazardous voltage (SELV / PELV) (e. g. IEC 60950-1).

The power supply may only be connected by means of the permanently connected cable.

4.3 Inputs/outputs

The RS485 interface assignment is described in the Standard Installation and Operation

Instructions.

The RS485 circuit may only be connected by means of the permanently connected cable to a

standard RS485 interface complying with the requirements for a safety sparation from

hazardous voltage (SELV).

4.4 Grounding and equipotential bonding

The electromagnetic flowmeter shall be connected to the equipotential bonding of the hazardous

area by using the external ground connection facility. The position of the external ground

connection facility is next to the cable entry.

For connecting the bonding conductor to the housing a ring cable lug suitable for a M5 screw

shall be used. Connection to the equipotential bonding of the hazardous area provides a safe

grounding of the equipment.

INFORMATION!

The power supply circuit is connected to ground inside the equipment. To avoid circulating

current the power supply circuit shall not be connected to ground at the connection side.

INFORMATION!

The RS485 circuit is connected to ground inside the equipment. To avoid circulating current the

RS485 circuit shall not be connected to ground at the connection side.

DANGER!

A missing connection to the equipotential bonding system may cause the danger of electrostatic

charging of the metallic parts and the risk of an ignition of a present explosive atmosphere.

BATCHFLUX 3200 C

www.krohne.com 08/2016 - 4005430201 - MA_Ex_AD_BATCHFLUX 3200 C-

5.1 Start-up

Start-up is only permitted when the electromagnetic flowmeter:

•is correctly installed in the system and connected.

•has been checked for the proper state with regard to its installation and connection

requirements.

•is free of explosive atmosphere inside the measuring tube

The user of the system must check before start-up in compliance with the national regulations

for checks before start-up.

5.2 Operation

Electromagnetic flowmeters must be operated in such a way that they remain within the

maximum and minimum permissible temperatures and pressures and the rated electrical

values.

Electromagnetic flowmeters may only be operated if the equipment parts necessary for safety

are effective in the long run, and are not rendered inoperable during operation.

WARNING!

Ignition risks caused by impact must be avoided.
