21. Returning for Repairs and Sample Devices
22. FHG Flow Meter Technical Data
Repairs on the flow meter and other components can be carried out quickly
and efficiently only if you include detailed information about the claim or
defect when returning the device. In addition, a safety sheet must be enc-
losed, clearly indicating what fluid has been used with the flow meter and
how hazardous this fluid is.
Compliance with the laws on occupational safety, such as Workplace Re-
gulations (ArbStättV), Accident Prevention Regulations and Regulations on
Environmental Protection, Waste Law (AbfG) and Water Act (WHG), re-
quire that businesses protect their employees and other people as well as
the environment from harmful effects when handling hazardous substances.
If additional precautions are required despite careful draining and clea-
ning of the flow meter, the associated required information must be inclu-
ded when returning the device. Please note that inspection and repair is
only performed on flow meters returned to Omega if the safety sheet of the
used fluid is enclosed and if the flow meter has been completely cleaned
and flushed. This is to protect our employees and makes our work easier.
In case of noncompliance with this rule, the devices are returned to
the sender without attaching postage to the package.
