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

The process liquids must be electrically conductive: ≥ 5 µS/cm ≥ 20 µS/cm for demineralized cold water

The full-scale range Q DN 2.5 - 150 / 1/10” - 6” Q

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

can be set as a function of the meter size:

100%

VARIFLUX 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 “EEx” installation and operating instructions (supplied only with hazardous-duty equipment).

Please note: Flowmeters for use in hazardous locations (EEx) have different dimensions and changed constructions.

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 VARIFLUX 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.

1 Important information for installation: PLEASE NOTE !

• 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 below.

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

• Temperatures

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

Ambient temperature Process temperature

Compact systems -25 to +60 °C (-13 to +140 °F) -20 to + 60 °C (-4 to +140 °F)

• 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 completely 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, random / 2g runs / 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.

4 Installation instructions VARIFLUX 6000

• 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 × DN), otherwise display may be unsteady.

• 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 inclining pipe section. If not possible, assure adequate velocity to prevent air, gas or vapour from collecting in upper part of flow tube.

Pumps

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

Install meter in low section of pipe.
