General safety notes

You can find the newest and/or additional information on the CD-ROM provided, in the handbook, the datasheet, special manuals, certificates and the download center at www.krohne.com.

Installation, mounting, commissioning, and maintenance can be performed only by trained personnel.

Responsibility for suitability and intended use of this instrument rests solely with the user.

The supplier accepts no liability for inappropriate use by the customer.

Improper installation and operation may lead to loss of warranty. Moreover, the "general terms and conditions" on the back of the bill apply, which form the basis for the sales contract.

If you have to send the device back to the manufacturer or supplier, fill out the form contained on the CD-ROM and enclose it with the device. Unless this form is completely filled out, it will unfortunately not be possible for the manufacturer to perform repair or inspection.

Respect general and local electrical safety requirements.

Piping with control valves

Vapor and gas measurement

1 Recommended: Installing the flowmeter upstreamupstreamupstreamupstream of the control valve, distance ≥ 5 DN2 Not recommended: Installing the flowmeter directly downstreamdirectly downstreamdirectly downstreamdirectly downstream of control valves, due to vor-

tex formation.

CAUTION!Prohibited: Installing the flowmeter in a lower pipe bend 1, risk of condensate formation 2!

Liquid measurement, prohibited installation locations

CAUTION!Prohibited: Installing the flowmeter in an upper pipe bend 1, risk of gas bubbles 2 forming!

CAUTION!Prohibited: Installing the device in a downstream pipe 3 or upstream pipe of a run-out 4.There is the risk of a partially-filled pipe!

Liquid measurement, recommended installation locations

CAUTION!It is absolutely necessary to maintain the required inlet and outlet runs!

1 Recommended: If the flowmeter is installed in a downpipe, it is absolutely essential to install a riser pipe immediately after it.

2 Recommended: Installing the flowmeter in an inclined riser pipe.3 Recommended: Installing the flowmeter in a vertical riser pipe.4 Recommended: Installing in the bottom pipe bend.

General installation instructions

CAUTION!Make sure that the connection flanges are sitting concentrically. On metering points with varying thermal loads the flowmeters are to be mounted with stress bolts (DIN 2509).

1 Installed length of flowmeter + thickness of gaskets.

Installing instruments in flange design

Install the flowmeter as follows:

• Fix the flowmeter to one side of a flange using bolts and fixing nuts 2.• Insert the gaskets 1 between sensor and flange and align them.• Check that the gaskets are concentric; they must not project into the pipe.• Install the gasket, bolts and fixing nuts on the other flange side.• Align the meter and the gaskets so that they are concentric.• Now tighten all nuts step by step alternately across the diagonal.

Installing instruments in sandwich design

Install the flowmeter as follows:

• Push the first bolt 3 through hole 5 of both flanges.• Screw on the nuts with washers at both ends of the bolt 3 but do not

tighten them.• Mount the second bolt through the holes 4.• Place the sensor 1 between the two flanges.• Insert the gaskets 6 between sensor 1 and flanges and align them.• Check that the flanges are sitting concentrically.• Install the remaining bolts, nuts and washers. But do not tighten the nuts

yet.• Turn the centering ring 2 anti-clockwise and align the flowmeter.• Check that the gaskets 6 are concentric; they must not extend into the

pipe.• Now tighten all nuts step by step alternately across the diagonal.

Turning the connection housing

Turn the connection housing as follows

• Switch off the power supply to the flowmeter.• Loosen the four Allen screws 1 on the underside of the converter

housing.• Lift the converter housing and turn it to the required position in 90° steps.• Screw the converter housing back on tightly.

DANGER!All work on the flowmeter electrics may only be carried out by appropriately trained personnel. The regional occupational health and safety directives and safety regulations must be observed without exception.Do not damage the electrical cable by over tightening. Do not undo the electrical plug connection.

Turning the LCD display

Turn the display as follows:

• Switch off the power supply to the flowmeter.• Unscrew the cover in front of the display 1 from the converter housing.• Pull the display 2 carefully a few centimetres out of the anchor fitting and

turn it to the required position 3.• Press the display back onto the spacer pins 4, until it clicks firmly into

place.• Turn the cover with gasket 5 back onto the housing and tighten it by

hand.

INFORMATION!If the flowmeter is installed in a vertical pipe, you have to turn the display by 90°; if installed below a pipe, turn 180°.

Protection category

Therefore it is essential to observe the following points:

• Use only original gaskets that are clean and free of any damage. Defective gaskets have to be replaced.

• The electrical cables used must be undamaged and must comply with regulations.

• The cables must be laid with a loop 1 upstream of the flowmeter to prevent water from getting into the housing.

• The cable glands 2 have to be tightened firmly.• Align the meter in such a way that the cable gland is never pointing up 3.• Close the unused cable glands using blanking plugs 4.

DANGER!The flowmeter meets the requirements of protection category IP 67.After all servicing and maintenance work on the flowmeter, the specified protection category has to be ensured again.

Electrical connections of the signal converter

The following procedures are to be performed:

• Unscrew the housing cover 1 of the electrical terminal compartment.• Connect the device using the standard procedures.• Pay attention to the correct polarity. • Connect the grounding 7 or 8.

The two grounding points are equally effective from a technical point of view.

• Lubricate the thread of the cover periodically before closing it.
