1.1 General notes
This additional instruction applies to explosion-protected versions of vortex flowmeters with
protection type flameproof enclosure "d", increased safety "e" and equipment dust-ignition
protection through enclosure "t", equipment category II 2 G and II 2 D, EPL Gb and EPL Db.
It completes the standard manual for the non-explosion protected versions.
The information given in this instruction contains only the data relevant to explosion protection
of category 2. The technical details given in the manual for the non-explosion protected versions
remain unchanged unless they will be excluded or replaced by this instruction.
1.2 EU conformity
The manufacturer declares with the EU declaration of conformity on his own responsibility
conformity with the protection goals of directive 2014/34/EU for use in hazardous areas with gas
and dust.
The EU declaration of conformity for the equipment category II 2 G and II 2 D is based on the EU
type examination certificate:

SAFETY INSTRUCTIONS
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 separate binary output and a separate 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 versions 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
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.
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.

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, under normal operation may occasionally occur.
Definition of zone 21 according to EN 1127-1, Appendix B:
An area in which an explosive atmosphere may occasionally occur in the form of a cloud of
flammable dust in the air under normal 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
• Product temperature T
• Nominal size DN
• Heat resistance of the connecting cable

DEVICE DESCRIPTION
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.
SITRANS FX330
•
Insulation must be limited to the piping. Unobstructed ventilation of the signal converter
must be ensured.
The permitted ambient temperature range is indicated on the nameplate; depending on the
device version it is T
The minimum product temperature is -40°C/ -40°F.
When using in zone 21, observe the maximum permissible product and ambient temperatures
for temperature class 2 and the information for use of a heat-resistant connecting cable and
cable entry.
