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

The process liquids must be electrically conductive: ≥ 20 µS/cm

The full-scale range Q ALTOFLUX M900: DN 10 - 300 /

ALTOFLUX 3080 K: DN 10 - 300 /

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

/8” - 12” Q

can be set as a function of the meter size:

100%

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

Flowmeters with ALTOFLUX primary heads are not certified for use in hazardous locations. Other flowmeters series are available for such applications.

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 ALTOFLUX 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.

2 Installation and operating instruction ALTOFLUX M900 and 3080 K

Standards and approvals

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

Items included with supply

ALTOFLUX M900 primary heads

• Primary head in the size as ordered • Compact flowmeter in the size as ordered

• Connecting wires for grounding, refer to

Section 7 “Grounding”

• Certificate of calibration data • Certificate of calibration data

• Grounding rings (optional), if ordered • Grounding rings (optional), if ordered

• Installation instructions • Installation instructions

Fitting accessories (stud bolts, nuts, gaskets, etc.) are not supplied with the flowmeter,

to be provided by customer!

ALTOFLUX 3080 K compact flowmeters

• Connecting wires for grounding, see Section 7 “Grounding”

• Installation and operating instructions for the signal converter

Handling

Do not lift flowmeter by the signal converter housing or the terminal box.

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

PLEASE NOTE

the temperature limits for storage and transport, see Page 4.

1 Important information for installation: PLEASE NOTE !

• Temperatures

Refer to Section 11 “Limits” for operating pressure and vacuum load based on flange standards and type of tube liner.

Compact system 3080 K

ALTOFLUX M900 -25 to +60 °C (-13 to +140 °F) In storage -20 to +60 °C (- 4 to +140 °F), (Neoprene liner)

avoid moisture and sunlight. Transport - 5 to +50 °C (- 4 to +140 °F), (Neoprene liner)

avoid moisture and sunlight.

• Location and position as required,

but electrode axis X – • – • – • – X must be approximately horizontal in a horizontal pipe run.

Y terminal box or converter housing

• 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: below 2.2g for compact flowmeters in the frequency range of 20-150 Hz with the IFC 090 K.

• Do not expose to direct sunlight, fit a sunshade if necessary, not included with flowmeter,

to be provided by customer.

• Large meter sizes (≥ DN 200 / ≥ 8”), use adapter pipes to allow axial shifting of the

counterflanges and to facilitate installation.

• 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.

Ambient temperature Process temperature

-25 to +60 °C (-13 to +140 °F)

-25 to +40 °C (-13 to +104 °F)

-25 to ≤ +60 °C (-13 to ≤ +140 °F)

-25 to > +60 °C (-13 to ≤ +194 °F)

-25 to > +60 °C (-13 to > +140 °F)

-25 bis +60 °C (all other liners)

4 Installation and operating instruction ALTOFLUX M900 and 3080 K

• 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 × 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 downstream of the flowmeter or upstream and downstream of the flowmeter.

2 Suggestions for installation

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

Highest point of pipe run Downpipe over 5 m (16 ft) length

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

Install air valve ✇ downstream of

Preferred locations

Downpipe

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

Long pipeline Always install control and shutoff valves

downstream of flowmeter.

Horizontal pipe run

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

Pumps

Open feed or discharge Never install flowmeter on pump suction side.

Install meter in low section of pipe.
