System description

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

The process liquids must be electrically conductive: ≥ 05 µS/cm

≥ 20 µS/cm for demineralized cold water

The full-scale range Q DN 10 - 150 /

/8” - 6” Q

can be set as a function of the meter size:

100%

= 0.1 - 760 m3/hr = 0.4 - 3350 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

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

Flowmeters with the ECOFLUX primary head are not certified for use in hazardous locations. Other flowmeter 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 ECOFLUX 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

1 Important information for installation: PLEASE NOTE

• Handling

Do not lift flowmeter by the signal converter housing or

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

the 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“.

• 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 20-50 Hz with the IFC 010 K

and 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.

• 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

open discharge
