1.4 Safety instructions
If these instructions are not followed, there is a risk of explosion.
Assembly, installation, start-up and maintenance may only be performed by personnel trained in
explosion protection!
CAUTION!
Operating conditions and place of installation may require compliance with additional standards,
directives or laws. The responsibility for compliance rests solely with the operator or his agent.

2.1 Device description
Vortex flowmeters measure and display the flow of flammable and non-flammable gases and
liquids. The signal converter includes either a 4...20 mA signal output with optional HART
®
communication or a bus connection. There are bus connections available according to the FISCO
model for connecting to the Foundation Fieldbus or Profibus PA. Signal converters with signal
output have a remote binary output and a remote current input.
The SITRANS FX330 remote version consists of the SITRANS FXS300 flow sensor and the
SITRANS FXT030 signal converter.
2.2 Marking
The marking of the devices in accordance with the description code is shown on the nameplates
below. On both the compact devices and the remote versions, the main plate is located on the
signal converter housing. On the remote versions there is an additional marking on the flow
sensor.
Compact devices with two signal converters for dual measurement (Dual Version) are each
marked with a nameplate, which is attached to each of the signal converter housings. The details
relevant to explosion protection are identical on both nameplates.

2.3 Flammable products
Atmospheric conditions
An explosive atmosphere is a mixture of air and flammable gases, vapours, mists or dusts under
atmospheric conditions.
It is defined by the following values T
atm
= -20...+60°C / -4...+140°F and P
atm
= 0.8...1.1 bar /
11.6...15.9 psi.
Outside of this range, for most mixtures no key figures are available for the ignition behaviour.
Operating conditions
Vortex flowmeters operate outside of atmospheric conditions, which means that explosion
protection according to the ATEX directive, regardless of the zone assignment, is fundamentally
not applicable due to the lack of key safety data for the interior of the measuring section.
2.4 Equipment category
Vortex flowmeters are designed in category II 3 G or EPL Gc according to EN 60079-0 und
EN 60079-15 for use in zone 2. The inside of the measuring unit is also approved for zone 2.
Vortex flowmeters are designed according to the "IECEx-Scheme" acc. to "Equipment Protection
Level [EPL] Gc".
CAUTION!
Operation with flammable products is only permitted as long as no explosive fuel/air mixture
builds up on the inside of the flowmeter under operating conditions. The operator is responsible
to ensure that the flowmeter is operated safely in terms of the temperature and pressure of the
products used.
In case of operation with flammable products the measuring units must be included in the
periodic pressure tests of the system.
INFORMATION!
Definition of zone 2 acc. to EN 1127-1, Appendix B:
An area in which an explosive atmosphere as a result of the mixture of flammable substances in
the form of gas, steam or mist with air is not expected to occur under normal operation. If,
however, such an atmosphere does occur it only lasts for a brief period of time.

2.5 Protection types
The vortex flowmeter is designed in the protection type "non-incendive" in accordance with
EN/IEC 60079-15:2010. Explosion protection is ensured in that there are no contacts or hot
surfaces with a sparking effect during operation.
2.6 Ambient temperature / temperature classes
Because of the influence of the temperature of the product, no fixed temperature class is
assigned to vortex flowmeters. The temperature class of these devices is rather a function of the
product temperature and ambient temperature that is present and the specific device version.
The classification is outlined in the following tables.
The tables take into account the following parameters:
•Ambient temperature T
amb
•Product temperature T
m
•Nominal size DN
•Heat resistance of the connecting cable

The permitted ambient temperature range is indicated on the nameplate; depending on the
device version it is T
amb
= -40...+65°C / -40...+149°F.
The minimum product temperature is -40°C/-40°F.
INFORMATION!
The maximum permissible product temperatures listed in the tables are valid under
the following conditions:
• The measuring device is installed and operated in accordance with the manufacturer's
installation instructions.
• It must be ensured that the flowmeter is not heated by the effects of additional heat radiation
(sunshine, neighbouring system components) and thus operated above the permissible
ambient temperature range.
• Insulation must be limited to the piping. Unobstructed ventilation of the signal converter
must be ensured.
