2.1 Using the flow meter
The flow meter, equipped with ultrasonic probes, is used to measure the flow of fluid (gas or liquid) in a
pipe. It is important to configure the flow meter correctly for its measurement results to be correct. You are
recommended to call on qualified staff from Ultraflux to ensure this is the case. This is strongly advised if
your equipment is used to regulate a process, intervene in a monitoring system, or in the case of other
applications for which an incorrect flow measurement could lead to risks.
In normal operation, the flow meter must not heat up to a level liable to cause burns. It is not necessary to
take any particular precautions to allow it to cool. Should the temperature of the unit rise abnormally, it is
recommended to power off the flow meter and call Ultraflux for expert advice. In the event of a fire inside
the flow meter, power it off without opening or touching it, then call the competent services in order to
secure the premises.
The flow meter must not be used beyond the possibilities and specifications given in this manual. The flow
meter must be stored in a dry place, with the packaging provided by Ultraflux in order to protect the parts
liable to be damaged by a shock. It is advised to wear PPE (personal protective equipment) suitable for
handling and installing the apparatus.
The flow meter must only be modified or disassembled by Ultraflux personnel. Ultraflux accepts no
responsibility should this rule not be respected.
The connectors must only be connected or disconnected with the power off and the equipment isolated.
For wiring and unwiring operations relating to function or maintenance, the protective
ground must be connected first and disconnected last .
The flow meter is designed for fixed installation and must not be connected to the mains
with a plug-in cable (risk of an unidentified or poorly identified phase on a mains socket).
It must be connected to a terminal board on which the phase is correctly identified.
Ultraflux accepts no responsibility for incidents which may occur following a failure to respect these
instructions.
2.2 Equipment connected to the flow meter
Any equipment connected to the unit must comply with its associated standard with regard to safety and
have SELV circuits (double insulation between primary and secondary). All equipment connected to the flow
meter must be disconnected before its protective ground is disconnected.
