1. PURPOSE
The purpose of this procedure is to describe the necessary maintenance and
preventive maintenance for the Fluenta Flare Gas Meter, FGM 160.
2. ABBREVIATIONS
FGM Flare Gas Meter
TFS Transducer Full Size
O&SC Operator & Service Console
3. GENERAL
The FGM 160 requires only minimum maintenance. Maintenance is carried out if
an error is detected or suspected to have occurred. In addition, Fluenta strongly
recommends a periodical maintenance routine to secure the operational uptime
of the meter. The checks below are a standard procedure. To get more
information or book maintenance service, contact Fluenta Service and Support.
The instructions are given for each major component in the flare gas metering
system and the time periods between each activity are also specified.
4. FIELD COMPUTER UNIT
The following should be checked every six months:
4.1 Connectors
Check that all connectors in the EEx-e housing are properly connected and that
there is no corrosion or contamination on the terminals.
4.2 Field Computer Preventive Maintenance
The following should be carried out every twelve months:
4.2.1 Inspection for Damages
Inspect the FGM 160 housing for damages. Make sure that the EEx-e housing
drain is operating correctly and that there is no contamination on the inside.
4.3 Functional Check
Every twelve months or after shutdown, the following should be carried
out:
Check all meter functions and if there are any indications of malfunction, go
through the Factory Acceptance Test Procedure for FGM 160, Fluenta doc. no.
62.120.018. This shall only be performed after installation, preferably by Fluenta
personnel, generally in collaboration with personnel responsible for daily
operation of the system.
Note:
Subjecting the computer to voltages without a Fluenta certified
personnel present causes loss of warranty.

In addition to the procedure already mentioned above, a reliable zero point check
and, if required, adjustment for the different transmitted ultrasonic signals
should be carried out. For this purpose, Fluenta service personnel use a portable,
specially designed piece of equipment.
Different signals will also be analyzed by Fluenta personnel, using the Operator &
Service Console (O&SC) program. The O&SC displays important information of
how the system operates, and how to troubleshoot potential errors, as the
signals can be interpreted, compared and optimized if necessary.
Use is recommended of experienced and qualified Fluenta personnel once a year
to run a total system functionality check as this will decrease the possibility of
system malfunction and increase the system’s reliability.
5. TRANSDUCERS AND BALL VALVES
5.1 Applicable for Transducer Full Size (TFS)
The following should be checked every six months or after shutdown:
Make sure that all nuts and bolts between the transducer holder and the
ball valve and between the ball valve and the transducer unit are properly
tightened.
All flanges must be parallel.
Check that the ball valves are open (not in contact with the transducers).
Check that the nut (on fitting) at the end of the packing box is tight.
6. CABLES
Inspect transducer cables and the FGM 160 cables for damages. Make sure that
the cables do not have any sharp bends (minimum internal radius of bend is
8 x D) and ensure that there is no contact between the cables and sharp edges
that can cause damages. Interfering equipment in the surroundings must be kept
in a safe distance from the cables and the rest of the FGM 160 equipment.
