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
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the relevant information is not taken into account.
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.

Alterations to the product, including opening or improper repairs of the product, are not
permitted.
If this requirement is not observed, the CE mark and the manufacturer's warranty will expire.
2.2 Laws and directives
General requirements
Installation of the equipment must comply with national regulations. For example, the
National Electrical Codes.
Instrument safety standards
The device has been tested at the factory, based on the safety requirements. In order to
maintain this condition over the expected life of the device the requirements described in
these Operating Instructions must be observed.
CAUTION

Safety notes
2.3 Lithium batteries
FST020 IP65 NEMA 4X
10 Operating Instructions, 02/2012, A5E03086487-05
CE marked equipment
The CE-mark symbolizes the compliance of the device with the following Directives:
● EMC-Directive 2004/108/EC
● Low Voltage Directive 2006/95/EC
2.3 Lithium batteries
Lithium batteries are primary power sources with high energy content designed to represent
the highest possible degree of safety.
WARNING
Potential hazard
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 specified 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
3.1 FST020 features
Description
The Siemens SITRANS FST020 IP65 NEMA 4X flow meters achieve highly accurate flow
measurement owing to the WideBeam ultrasonic transit-time technology. The sensors are
mounted on the outside of the pipe, preventing contact with the medium
The sensor construction makes installation and commissioning of even the largest sizes very
straight forward and easy. The sensors deliver true multi parameter measurements i.e.
volume flow.
Note
This operating Instructions manual applies to the following FST020 IP65 NEMA 4X operating
systems: Version 2.04.04 and later.
3.2 NEMA 4X Transmitters
SITRANS FST020 Transmitters
The SITRANS FST020 NEMA 4X series transmitters are available in AC or DC powered
versions. The transmitters include an LCD display providing flow rate, diagnostics data and
keypad interface to access on-screen software setup menus.

4.1 Determining a location
WARNING
Electrical Shock Hazard
Hazardous Voltage. May cause death or serious personal 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.
Sensor Location in piping system
The optimum location in the system depends on the application
● For liquid applications the presence of excessive gas or air bubbles in the fluid 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.

4.2 Use according to specifications
FST020 IP65 NEMA 4X
14 Operating Instructions, 02/2012, A5E03086487-05
4.2 Use according to specifications
"Use according to specifications" covers:
● Use within technical limits.
● Consideration of liquid specifications and references.
● Consideration of specifications as to installation, commissioning and maintenance.
Do NOT:
● Use the sensors as a footboard for installation purposes.
● Change the flow meter in any way. For e.g. decomposition of material in connection with
processing, welding and use of accessories and spare parts not approved by Siemens.
Note
If the flowmeter is not used according to the specifications, the manufacturer cannot be
held responsible for any resulting damage.
4.3 Application Guidelines
Basic Requirements
● Determine pipe material and dimensions.
● Avoid vertical pipes flowing in a downward direction.
● Avoid installation of sensors on the top and bottom of horizontal pipes, where possible.
● Select a location with the longest straight run of pipe.
● Identify upstream piping configuration (elbow, reducer, etc.).
● Pipe surface should be smooth and, if necessary, free of dirt and grease.
● Avoid pressure reduction components upstream, where possible.
● Avoid mounting on or near weld seams.
● Pipe must be full during set-up.

WARNING
Hazardous Voltage
May cause death or serious personal injury. Disconnect power before working on this
product.
Wall Mounting
The transmitter can be mounted on any wall surface including wood, metal or concrete. Use
the appropriate bolts and screws as needed for your mounting application and adhere to
local codes.
● Recommended mounting: directly to wall or to electrical cabinet back panel.
● If alternate mounting surface is used it MUST support four times the weight of the unit.
