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
standards and EC regulations. It can, however, be a source of danger if used incorrectly or for
anything 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
electronics 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
“Declaration 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.

delivery papers with the data on the nameplate.

A0006981

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

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
manufacturer 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. 74-06.
Endress+Hauser 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

NOTICE

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 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.

• 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: L

i

≥10 mm.

A0006976

Fig. 5: Installation conditions

Orientation

• For horizontal pipes: lateral installation.
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.

3.4.3 Inlet and outlet run

NOTICE

The thermal measuring principle is sensitive to disturbed flow conditions.

‣ As a general rule, install the measuring device as far away as possible from any flow

disturbances. For further information → ISO 14511.

‣ If possible, install the sensor upstream from fittings such as valves, T-pieces, elbows, etc.
‣ To attain the specified level of accuracy of the measuring device, the inlet and outlet runs

mentioned below must be maintained at the very minimum.

‣ If there are several flow disturbances present, the longest specified inlet run must be

maintained.
