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 measuring 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.

3. 4 Installation instructions
3.4.1 Installation conditions
!Note!
The sensor requires a fully developed flow profile for correct monitoring. For this reason, steady-
ing 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. 4, item 1). Use a suitable open-ended wrench for this task (see
Table →Kap. 3. 3).
• 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. 4: Installation conditions
Orientation
• For horizontal pipes: lateral installation.
!Note!
Installation from above only if the pipe is completely filled with
medium.
• For vertical pipes: installation in the ascending pipeline.
A0006977
Fig. 5: Correct orientation
"Caution!
• Do not install in down pipes open towards the end.
• The sensor tip should never touch the pipe wall.

"Caution!
To avoid any damage to the analog input of a PLC, do not connect the active PNP switch output
of the device to the 4 to 20 mA input of a PLC.
!Note!
DESINA (→Chap. 5.1.4, basic settings):
R2 = diagnosis/NC contact (more information on DESINA can be found at www.desina.de).
"Caution!
Once connected to the power supply, the sensor tip of the device heats up! The temperature can
reach up to approx. 90 °C (194 °F).
