1.3 Safety information and protective measures
1.3.1 General information
Handling or using the device incorrectly can result in personal injury or material damage.
Read this Chapter carefully and ensure you observe the safety precautions during all work
on the FLOWSIC100. Always observe the warnings provided in these Operating
Instructions.
The following applies at all times:
● The relevant legal stipulations and associated technical regulations must be observed
when preparing and carrying out work on the installation.
● Extreme caution must be exercised in installations with high hazard potential (pressure
pipes, installations with explosive atmospheres). The applicable special regulations
must be followed at all times.
● All work must be carried out in accordance with the local, system-specific conditions
and with due consideration paid to the operating dangers and specifications.
● The Operating Instructions for the measuring system as well as system documentation
must be available on site. The instructions for preventing danger and damage con-
tained in these documents must be observed at all times.
1.3.2 Hazard through electrical equipment
The FLOWSIC100 measuring system is an item of electrical equipment designed for use in
industrial high-voltage systems. Make sure the power supply is switched off before working
on mains connections or live components. If necessary, replace shock protection
measures before reconnecting the power supply.
1.3.3 Hazard through hot, corrosive and/or pressurized gases
The sender/receiver units are mounted directly on the gas-carrying duct. In installations
with a low hazard potential (no risk of injury, ambient pressure, low temperatures, no risk of
explosion), these units can be installed and removed while the installation is in operation,
providing the applicable specifications and safety regulations for the system are adhered
to and all necessary and suitable protective measures are taken.
1.3.4 Hazards through ultrasonic signals
Do not expose unprotected hearing to the sonic beam of the transducer (especially type H).
Wearing suitable hearing protection is recommended when inspecting the duct, connecting
the device outside the duct or similar activities.
WARNING:
Systems and processes with toxic gases, high pressure or high temperatures
must be shut down before the sender/receiver units are installed or removed.
DANGER: Hot gas
Hot gas can escape should the purge air supply fail when using externally
purged devices (device types PM, PH and PH-S) in pressurized pipelines and
ducts. This can lead to serious damage to health and material damage to the
system. The system owner must take suitable protective measures to prevent
such damage. Technical solutions for the FLOWSIC100 to prevent gas escap-
ing should the purge air fail are available from the manufacturer on request.
