Intrinsic Safety

Intrinsic safety is an electronic hardware protection concept that
ensures there are no conditions under which the equipment can
operate that could cause a release of energy sufficient to ignite a
hazardous gas or dust mixture. Devices that meet the low power,
current-limited design criteria are deemed Intrinsically Safe (IS).
Special design, testing, quality, and inspection rules apply to
manufacturers and users of IS equipment due to the critical nature
of their deployment in hazardous areas. Areas where hazardous
conditions can be expected to be present on a constant basis are
classified (rated) as Class I, Division 1 or Zone 0.

The FlowHawk flow monitor (Models 8000-FHK and 8000-FHK-
60C) is certified to ATEX (Atmosphere Explosibles) standards in
Europe and is certified for use in all classified (hazardous) sanitary
sewer and industrial hazardous areas. Many rest-of world countries
accept ATEX certification in lieu of their country-specific
requirements. It is the customer’s responsibility to ensure that
the certification(s) provided for the IETG equipment meets the
applicable regulatory requirements.

Note: FlowHawk models include only the 8000-FHK and
8000-FHK-60C.

FlowHawk System Certification

The FlowHawk unit and associated telemetry equipment are
certified for use only with approved sensors, communication cables,
and telemetry equipment. Connection of any non-approved devices
could result in unsafe operation and will immediately void the
warranty and IS certification.

FlowHawk is an approved application and, therefore, will
not void the FlowHawk warranty. However, because the
