Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage
to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices
referring only to property damage have no safety alert symbol. These notices shown below are graded according to
the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be
used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property
damage.
Quali󹪝ed Personnel
The product/system described in this documentation may be operated only by personnel quali󹪝ed for the speci󹪝c
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

1.7 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is necessary
to implement – and continuously maintain – a holistic, state-of-the-art industrial security
concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected to
an enterprise network or the internet if and to the extent such a connection is necessary and only
when appropriate security measures (e.g. 󹪝rewalls and/or network segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
https://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends that product updates are applied as soon as they are available
and that the latest product versions are used. Use of product versions that are no longer
supported, and failure to apply the latest updates may increase customer’s exposure to cyber
threats.

2.5 Lithium batteries
Lithium batteries are primary power sources with high energy content designed to represent the
highest possible degree of safety.
WARNING
Lithium batteries
Explosion Hazard - Can cause death or serious injury.
Lithium batteries may present an Explosion Hazard if they are abused electrically or
mechanically. This is in most circumstances associated with the generation of excessive heat
where internal pressure may cause the cell to rupture.
Thus the following basic precautions should be observed when handling and using lithium
batteries:
• Do not short-circuit, recharge or connect with false polarity.
• Do not expose to temperature beyond the speci󹪝ed temperature range or incinerate the
battery.
• Do not crush, puncture or open cells or disassemble battery packs.
• Do not weld or solder to the battery’s body.
• Do not expose contents to water.

Description 3
3.1 Overview
SITRANS FST020 ultrasonic 󹪞ow meter systems consist of a transmitter and a sensor. The
following table lists the available combinations of transmitters and sensors.
Transmitter Sensor type
FST020 FSS200 family
DN 15 to DN 10m (0.5" to 360")
3.2 Design
The transmitter reads the measured process values from the sensor and calculates derived
values. It provides Modbus communications, 1x 4-20ma, 1x relay, and 1x Pulse/Frequency, USB
service port, and a local display. It also adds functionalities such as totalizers, access control,
diagnostics, and con󹪝guration. The local user interface consists of a display and four buttons for
user interaction.
The transmitter has a modular design with discrete, replaceable electronic modules and
connection boards to maintain separation between functions and facilitate 󹪝eld service. All
modules are fully traceable and their provenance is included in the transmitter setup.
The SITRANS FST020 is available as:

Installing/mounting 4
4.1 Chapter overview (transmitter)
This chapter describes how to install the wall mount housing transmitter.
Wall mount housing
The wall mount housing transmitter can be mounted either on a wall or on a pipe (with optional
pipe mount bracket), see Installation instructions (Page 20).
4.2 Installation location requirements
4.2.1 Environment
SITRANS F 󹪞owmeters with minimum IP65/NEMA 4X enclosure rating are suitable for indoor and
outdoor installations.
Process pressure and medium temperature
If applicable, make sure that speci󹪝cations for rated medium temperature (TS) plus ambient
temperature that are indicated on the device nameplate / label will not be exceeded.
Aggressive atmospheres
Ensure that the device is suitable for the application and that it is installed where there is no risk
of penetration of aggressive vapors.
Direct sunlight
Prevent the device from overheating or materials becoming brittle due to UV exposure by
protecting it from direct sunlight. Make sure that the maximum permissible ambient
temperature is not exceeded. Refer to the information in Technical speci󹪝cations (Page 77).
WARNING
Electrical shock hazard
May cause death or serious injury
Disconnect power before working on this product.
Upstream / Downstream
Avoid long drop lines downstream from the sensor to prevent the meter pipe from draining.
Avoid installing the sensor upstream of a free discharge in a drop line where possible.
SITRANS FST020 IP65 (NEMA 4X)
Operating Instructions, 05/2022, A5E41425845-AC 19

Sensor Location in piping system
The optimum location in the system depends on the presence of excessive gas or air bubbles in
the 󹪞uid may result in erroneous measurements. Therefore, it is preferred not to install the
sensor at the highest point in the system, where gas / air bubbles will be trapped. For liquids it
is advantageous to install the sensor in low pipeline sections, at the bottom of a U-section in the
pipeline.
