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.

• Incoming acceptance:

Check the packaging and the device for damage. Check that the goods delivered are complete

and nothing is missing.

•Storage:

Storage temperature -40 °C to +85 °C (-40 °F to 185 °F).

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.

A3: 1x analog output and 1x PNP switch output

"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).
