Intended use
Type 8098 FLOWave L
2 INTENDED USE
Use of the device that does not comply with the instructions could present risks to people, nearby
installations and the environment.
The Type 8098 FLOWave L flowmeter uses the Surface Acoustic Wave (SAW) measurement principle
and is intended to measure the flow rate of liquids that have all of the following characteristics:
- clean liquids
- non emulsified liquids (homogeneous liquids)
- liquids that are free of air bubbles
- liquids that are free of gas bubbles
- liquids that are free of solids.
▶The device is not intended to measure the flow rate of liquids if gas bubbles are present, whatever the origin
of the bubbles (air intake, cavitation, degassing…).
▶Use the device in compliance with the characteristics and the conditions of commissioning and use specified
in the contractual documents and in the Operating Instructions.
▶Protect the device against electromagnetic interference, ultraviolet rays and, when installed outdoors, against
the effects of climatic conditions.
▶Only operate a device in perfect working order.
▶Properly transport, store, install and operate the device.
▶Only use the device as intended.
2.1 Device with ATEX certification
Danger
Risk of explosion in the event of improper use of the device in potentially explosive areas.
▶Observe the specifications of the ATEX-conformity certificate.
▶Observe the specifications in the ATEX supplement for Type 8098 FLOWave L. The supplement is available
at country.burkert.com.
The ATEX certification is only valid if the device is used as described in the ATEX supplement.
If unauthorized changes are made to the device, then the ATEX certification becomes invalid.

5.7 Marking of the Unique Serial Number (USN)
The USN is marked on the side of the sensor. The USN is built with the device article number and the device
serial number.
5.8 Device status indicator
Ex works, the device status indicator changes its colour and state based on the NAMUR NE 107 recommendation.
If several states exist simultaneously, the state with the highest priority is displayed. The priority is determined
by the severity of the deviation from standard operation (red indicator = failure, error or malfunction = highest
priority).
Device status

Colour code
(for a PLC)
Description Meaning
Colour Red 5 Failure, error,
malfunction
Due to a malfunction of the device or its periphery,
the measured values can be incorrect.
Orange 4 Function check Ongoing work on the device (for example,
checking the correct behaviour of the outputs by
simulating measurement values); the output signal
is temporarily invalid (e.g. frozen).
Yellow 3 Out of
specification
The ambient conditions or process conditions for
the device are outside the permitted ranges.
Device internal diagnostics point to problems in
the device or with the process properties.
