System description

PROFIFLUX electromagnetic flowmeters are precision measuring instruments designed for the
linear flow measurement of process liquids.

1

The process liquids must be electrically conductive: ≥ 05 µS/cm (≥ 10 µS/cm for DN 2.5/

/10”)

≥ 20 µS/cm for demineralized cold water

The full-scale range Q
DN 2.5 - 100 /

1

/10” - 4” Q

can be set as a function of the meter size:

100%

= 0.01 - 340 m3/hr = 0.03 - 1500 US Gal/min

100%

This is equivalent to a flow velocity of 0.3 - 12 m/s, or 1 - 40 ft/s.

Product liability and warranty

PROFIFLUX electromagnetic flowmeters are designed solely for measuring the volumetric
flowrate of electrically conductive, liquid process products.

Special codes and regulations apply to their use in hazardous locations, and these are referred to
in the special “Ex” installation and operating instructions (supplied only with hazardous-duty
equipment).

Responsibility as to suitability and intended use of these electromagnetic flowmeters rests solely
with the operator.

Improper installation and operation of the flowmeters (systems) may lead to loss of warranty.
In addition, the “General conditions of sale” forming the basis of the purchase contract are

applicable.
If PROFIFLUX flowmeters need to be returned to Krohne, please note the information given on

the last-but-one page of this manual. Krohne regret that they cannot repair or check your
flowmeter(s) unless accompanied by the completed form sheet.

Standards and approvals

Please refer to the installation and operating instructions for the signal converter.

signal converter housing or

Do not set flowmeter down on signal
converter housing or terminal box.

• Use only solventless detergents to clean the signal converter housing (polycarbonate).

• Temperatures

For operating pressure and vacuum load based on flange standards, see Section 10
“Technical data“.

• Measuring tube must be completetly filled at all times.

• Direction of flow is arbitrary. Arrow on flowmeter can normally be ignored.

For exceptions, refer to Section ”Factory settings” in the installation and operating
instructions for the signal converter.

• Stud bolts and nuts: to fit, make sure there is sufficient room next to the pipe flanges.

• Vibration: support the pipeline on both sides of the compact flowmeter.

Level of vibration in conformity with IEC 068-2-34:
20-500 Hz, ran dom / 2 g rms / 30 minutes / x, y, z directions.

• Do not expose to direct sunlight,

fit a sunshade if necessary, not included with flowmeter, to be provided by customer.

• Strong electromagnetic fields, avoid in vicinity of flowmeter.

• Straight inlet run minimum of 5 ××DN and outlet run minimum of 2 ××DN,

(DN = meter size), measured from the electrode axis.

• Vortex and corkscrew flow: increase length of inlet and outlet runs or install

flow conditioners.

• Mixing different process liquids: install flowmeter upstream of mixing point or at an

adequate distance downstream (minimum of 30 x DN), otherwise display may be unsteady.

• Plastic pipes and internally coated metal pipelines: grounding rings required,

see Section 7 ”Grounding”.

• Insulated pipeline: do not insulate flowmeter.

• Zero setting not necessary. To check, it should be possible to set ”zero” flow velocity

in the completely filled measuring tube. Shutoff valves should therefore be provided either
downsteam of the flowmeter or upsteam and downstream of the flowmeter.

2 Suggestions for installation

To avoid measuring errors due to gas/air inclusion or to pipe runing empty please observe the
following:

Highest point of pipe run

(Air bubbles collect in measuring
tube - faulty measurements!)

Preferred
locations

Downpipe

”Zero” flow
velocity.
Line drained.
Faulty
measurements!

Horizontal pipe run

Install in slightly ascending pipe section. If not
possible, assure adequate velocity to prevent air,
gas or vapor from collecting in
upper part of flow tube.

Open feed or discharge

Install meter in low section of pipe.

Downpipe over 5 m (16 ft) length

Install air valve X downstream of
flowmeter.

Long pipeline
Always install control and shutoff valves

downstream of flowmeter.

Pumps
Never install flowmeter on pump suction side.

> 5m

> 16 ft
