Electromagnetic 2-wire flowmeters with IFC 040 signal converter are precision instruments designed for linear flow measurement of liquid products.

The process liquids need to be electrically conductive, ³ 5 µS/cm (for cold demineralized water ³ 20 µS/cm).

Depending on the meter size, the full-scale range Q100%

can be set between 85 Liter/h and 763 m3/h, equivalent to a flow velocity v = 0,3- 12 m/s, see flow table in Section 5.1.

3URGXFW OLDELOLW\ DQG ZDUUDQW\

Electromagnetic 2-wire flowmeters with IFC 040 signal converter are designed solely for measuring the volumetric flowrate of electrically conductive, liquid process products.

These flowmeters are also available for use in hazardous areas. Special codes and regulations apply in this connection and these are referred to in the special ‘EEx’ notes.

Responsibility for 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 flowmeters need to be returned to KROHNE, please note the information given on the last-but- one page of these Instructions. KROHNE regret that they cannot repair or check your flowmeter(s) unless accompanied by the completed form sheet.

•Location and position as required, but in a horizontal pipe run electrode axis

X – • – • – • – X

should be approximately horizontal.

Y Signal 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 Sect. 3.2 “Factory settings” in the Installation and Operating Instructions for the signal converter.

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

•Vibration: support pipeline on both sides of flowmeter. Level of vibration in conformity with IEC 068-2-34: below 2.2g for flowmeters in the 20-150 Hz frequency range.

•Do not expose to direct sunlight: fit a sunshade if necessary, not included with flowmeter, to be provided by customer.

•Avoid strong electromagnetic fields in vicinity of flowmeter.

•	Inlet run 5 × DN and outlet run 2 × DN, straight pipeline,
	measured from electrode axis (DN = meter size)

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

•Mixing different process liquids: install flowmeter upstream of the mixing point or at an adequate distance downstream (min. 30 × DN), otherwise display may be unsteady.

•Plastic pipelines and internally coated metal pipelines: grounding rings required, refer to Sect. 1.7 “Grounding“.

•Insulated pipeline: do not insulate flowmeter.

•Zero setting: not necessary. To check, it should be possible to set “zero“ flow velocity when the measuring tube is completely filled. Shutoff valves should therefore be provided, either downstream of the flowmeter or upstream and downstream of the flowmeter.

•Electrical connection to VDE 0100 “Regulations governing heavy-current installations with line voltages up to 1000 V” or equivalent national regulations.

•Hazardous areas: subject to special regulations,

refer to special ‘EEx’ information (texts with grey background).

Section 1.5

Part A Installation and Start-up

1.5 Installation in the pipeline

•Installation material not included, to be provided by customer (stud bolts, nuts, gaskets, etc.).

•Pipe flanges and operating pressure: refer to “limits“ tables in Section 5.6

•Distance between pipe flanges:

see fitting dimension a in Section 5.5 “Dimensions and weights“

•High-temperature service

Where process temperatures exceed 100°C/212°F, provide facilities to compensate for longitudinal expansion on heat-up of the pipeline.

For short pipelines, use resilient gaskets, and

for long pipelines install flexible pipe elements (e.g. elbows).

•Flange position: Install flowmeter in line with pipe axis. Pipe flange faces must be parallel to each other.

•Gaskets

No additional gaskets required for primary heads fitted with tube liners of Teflon® - PFA or Teflon® - PTFE. Refer to Sect. 1.6 for torques.

•Grounding rings / protection rings (option)

On plastic pipelines and internally coated metal pipelines, grounding rings are required to form the conductive connection with the process liquid. Refer to Sect. 7 “Grounding“ for electrical connection.

Please note: The cylindrical neck must be inside the measuring tube (to protect the liner, particularly at the inlet edge).

1.7 Grounding

•All flowmeters must be properly grounded to avoid personnel shock hazard.

•The ground conductor should not transmit any interference voltages, therefore do not ground any other electrical devices together with this conductor.

•Protective separation (PELV) must be ensured

(VDE 0100 / VDE 0106 or IEC 364 / IEC 536, or equivalent national regulations).

•For measurement reasons, connect an FE functional ground conductor.

2.1 Information on electrical connection and connection data

•Rated values: The flowmeter housings protect the electronic equipment from dust and moisture and should always be kept properly closed. Creepage distances and clearances in air have been dimensioned in conformity with VDE 0110 and IEC 664 for contamination category 2. Supply circuits and output circuits are designed to meet the standards of overvoltage classes III and II, respectively.

•Safety isolation: The flowmeter must be provided with an isolating facility.

•Note information on instrument nameplate(s).

•PE conductor / FE functional ground must be connected to the separate U-clamp terminal in the terminal compartment of the signal converter.

•For measurement reasons, the flowmeter must be properly grounded. The ground conductor should not transmit any interference voltages. Therefore, do not ground any other electrical devices together with this conductor.

•In hazardous areas, the ground conductor is used simultaneously for equipotential bonding.

CAUTION: Where a power booster (1L= / 0L=) is used, electrical isolation is required between the power booster and the current output, otherwise the electronic equipment will substain irreparable damage.
