1 Safety instructions

1. 1 Designated use

The Flowphant®T is a flow switch for monitoring mass flow rates in industrial processes. The

device is designed to meet state-of-the-art safety requirements and conforms to applicable stan-

dards and EC regulations. It can, however, be a source of danger if used incorrectly or for any-

thing other than the designated use.

1. 2 Installation, commissioning and operation

Installation, electrical connection, commissioning, operation and maintenance of the measuring

system must be carried out by trained, qualified specialists authorized to perform such work by

the facility's owner-operator. The specialist must have read and understood these Operating

Instructions and must follow the instructions they contain. The device may only be modified and

repair work carried out if this is explicitly permitted in the Operating Instructions. Damaged

devices which could be a source of danger may not be commissioned and must be labeled and

identified as defective.

1. 3 Operational safety

• Functional safety

The Flowphant®T flow switch has been developed in accordance with the IEC 61508 and

IEC 61511-1 (FDIS) standards. The device version with a PNP switch output and additional

analog output is equipped with features for detecting and preventing errors within the elec-

tronics and software.

•Ex-area

The Flowphant®T is not approved for use in Ex-areas.

1. 4 Return

The following procedures must be carried out before a device is returned to Endress+Hauser:

• Always enclose a fully completed “Declaration of Contamination” form with the device. Only

then can Endress+Hauser transport and examine a returned device. A copy of the “Declara-

tion of Contamination” can be found on the second last page of these Operating Instructions.

• Remove all fluid residues. This is particularly important if the fluid is hazardous to health, e.g.

flammable, toxic, caustic, carcinogenic, etc.

#Warning!

Do not return a device if you are not absolutely certain that all traces of hazardous substances

have been removed, e.g. substances which have penetrated crevices or diffused through plastic.

2 Device identification

2.1 Nameplate

To identify your device, compare the complete order code and the version information on the

delivery papers with the data on the nameplate.

a0006981

Fig. 1: Nameplate for device identification (as example)

!Note!

The release number indicates the change status of the device. A change in the last two figures

does not have any affect on the compatibility, Chap. 8.4.

2.2 Certificates and approvals

CE mark, declaration of conformity

On leaving the factory, the device was in perfect condition from the point of view of safety. It

complies with the standards EN 61010 -1 "Protection Measures for Electrical Equipment for

Measurement, Control, Regulation and Laboratory Procedures" and with the EMC requirements

of IEC/EN 61326. The device meets the legal requirements of the EU Directives. The manufac-

turer confirms a positive completion of all tests by fitting the unit with a CE mark.

Hygiene standard

The DTT35 flow switch meets the requirements of Sanitary Standard no. 74-03. Endress+Hau-

ser confirms this by applying the 3–A symbol (not valid for process connection conical

metal-metal).

3. 4 Installation instructions

3.4.1 Installation conditions

!Note!

The sensor requires a fully developed flow profile for correct monitoring. For this reason,

steadying sections (5x DN) must be provided in the pipe after a pump, pipe bend, internal fittings

and cross-sectional changes.

"Caution!

Do not turn the device into the process connection thread at the housing. Always install the

device at the spanner flats (Fig. 5, item 1). Use a suitable open-ended wrench for this task (see

Table →Chap. 3.3.1).

• The onsite display can be rotated electronically 180°, →Chap. 5. 1 "Onsite operation".

• The upper housing section can be rotated mechanically up to 310°.

• The sensor tip should be completely surrounded by medium.

• Position the sensor tip in the area of maximum fluid velocity (pipe

center).

• Minimum sensor immersion length: Li ≥10 mm.

A0006976

Fig. 5: Installation conditions

Orientation

• For horizontal pipes: lateral installation.

!Note!

Installation from above(see Fig. 5) only if the pipe is completely

filled with medium during operation.

• For vertical pipes: installation in the ascending pipeline.

• Installation of DTT35 by min. 3° inclination, because of self

draining.
