Installation and Operation Instructions
Rotary Gas Meter Type FMR 171/241/260
WARNING
If there remain any questions or remarks after reading these instructions,
please contact the supplier of this product. Before installing the gas meter
the international, national, as well as local and company regulations related
to this product should be known.
A more extensive manual of this gas meter is available on request.
ENVIRONMENTAL CONDITIONS OF THE METER:
Mechanical class M2 & Electromagnetic class E1
Max. Operating temperature range from -40°C to +70°C.
Meter can be installed in open air.
Avoid direct sunshine on the meter.
Minimal IP-classification of Index: IP54 (splash proof)
INSTRUCTIONS:
1) Check the meter for damage due to transportation and handling. The rotors should
rotate freely.
2) Check the flow direction, as indicated with an arrow on the Pm-
indication label on the meter. In case the flow direction is incorrect, this
can be changed to a reversed flow (horizontal, right to left) by turning
the index plate. For the positions of the Pressure and Temperature
connections see figure 4.
3) The piping on the inlet side of the meter must be clean (free of dirt, welding beads
and pipe scale). It is recommended to install a 100 micron filter upstream of the
meter. For new installations it is recommended to install a wire mesh screen (250
micron) for the first weeks of operation.
4) The meter must be installed free of piping stress.
5) Level the meter within 5mm/m side-to-side and front-to-back
6) TIGHTEN THE FLANGE BOLTS CROSSWISE AND REGULARLY (for the dimensions of the
flange bolts and the applied tightening torque on the different sizes see figure 3).
7) The meter is shipped with empty oil reservoir. Fill the oil reservoir at the front side of
the meter with the supplied oil to the indicated level (see figure 1). For a correct
II 2 G T4

FMR 171/241/260 QA Installation and Operation Instructions –Page 2 of 20
reading of the oil level it should stabilize for a few minutes. To remove or place the oil
plug you need an Allen key.
8) Pressurize the meter with care to avoid overloading. The pressure change should never
exceed 350 mbar/sec.
9) Connect the electrical pulsers in accordance with the connection diagram (see figure
2). The connector is in conformance with IP67 as long as the companion plug or the
protection cap is connected.
10) An indication of the meter condition can be obtained by monitoring the pressure drop
over the meter (Pm- vs. P-point). It is recommended that the pressure drop over a new
meter is measured. This value can be compared to future measurements.
PRECAUTIONS:
1) Never use the meter as a spool piece during welding.
2) The meter must be depressurised before filling or adding oil.
3) Before removing the meter, the oil should be drained.
4) The meter should be transported and stored with the rotor axis horizontal.
5) Use only devices with electrical characteristics as recommended (see connection
diagram figure 2)
6) The maximum tightening torque on the Pressure and Temperature tapping connections
is: 18 Nm. To tighten the swivel nuts; use 2 wrenches to avoid over tighten and
damage the meter body.
7) Avoid mechanical shock during handling and transportation of the meter.
8) Avoid strong magnet fields close to the meter (particular the index), since they can
affect the metrological performance and/or interrupt the pulse generators.
9) Seal all plugs and sight glasses to overcome fraud and/or theft of gas.
10) Lock (two bolts M5) and seal the index after adjusting it in the right position.
all BLUE or TABLET seals are ‘Metrological Seals’; do NOT
remove them
all ORANGE seals are ‘Service Seals’; they can/may be removed
and replaced

Installatie en bedieningshandleiding
Rotor Gas Meter Type FMR 171/241/260
OMGEVINGSCONDITIES VAN DE METER:
Mechanisch klasse M2 en Elektromagnetisch klasse E1
Bedrijfstemperatuur -40°C tot +70°C.
Meter kan in de open lucht worden opgesteld.
Voorkom directe instraling van zonlicht
Minimale IP Klasse van telwerk: IP54, mits aangesloten volgens voorschrift.
INBOUWINSTRUCTIES:
1) Controleer de meter op beschadigingen veroorzaakt door het transport. De rotoren
moeten vrij draaien. In geval van beschadigingen meld dit bij de leverancier van dit
product.
2) Controleer de stromingsrichting zoals aangegeven op de meter (Pm
label met pijl) en sluit de druk- en temperatuursensors aan op de
daarvoor bestemde aansluitingen. Het maximale aanhaalkoppel voor
de druk- en temperatuuraansluitingen is 18 Nm.
3) De in en uitlaat pijpstukken van de meter dienen vrij te zijn van vuil,
roest, lasslakken, etc. Het wordt aanbevolen, om in de eerste weken van gebruik een
250 micron filter te installeren.
4) De meter moet vrij van installatiespanningen geïnstalleerd worden.
5) De meter moet in alle richtingen horizontaal vlak geïnstalleerd worden met een
maximale afwijking van 5mm per meter.
6) HAAL DE FLENSBOUTEN KRUISLINGS EN EVENREDIG aan met een maximaal
aanhaalmoment zoals weergeven in onderstaande tabel.
7) De meters dienen altijd getransporteerd te worden zonder olie in het carter.
Vul het carter met de meegeleverde olie tot het niveau als weergegeven in
onderstaande figuur. Wacht een minuut om het olieniveau te laten stabiliseren.
WAARSCHUWING
Bij vragen of onduidelijkheden na het lezen van de handleiding wordt
verzocht contact op te nemen met de leverancier van het product. Voor
het installeren en in gebruik nemen dienen de van toepassing zijnde
nationale / internationale en bedrijfsregels bekend te zijn. Een meer
uitgebreide handleiding (Engelse taal) is op verzoek verkrijgbaar.

FMR 171/241/260 QA Installation and Operation Instructions –Page 4 of 20
8) Breng de meter langzaam (maximaal 350mbar/sec) op druk en voorkom daarmee
overbelasting.
9) Sluit de elektrische contacten aan volgens onderstaand figuur. De connector en het
telwerk hebben een classificatie IP67 zolang het contradeel of de beschermingskap van
de connector zijn aangesloten.
VOORZORGSMAATREGELEN:
1) Gebruik de meter niet als vulstuk bij laswerkzaamheden.
2) Voordat een van de pluggen (olie vulplug, olie aftapplug, HF plug, etc.) van het
voordeksel losgedraaid wordt, dient de druk in de meter afgelaten te worden.
3) Voordat de meter uit de leiding wordt gehaald dient de olie uit het carter af getapt te
worden. Voer de afgetapte olie af volgens geldende milieu wetgeving/richtlijnen.
4) De meter moet met de rotorassen horizontaal getransporteerd en opgeslagen worden.
5) Sluit alleen elektrische apparaten aan met de juiste elektrische eigenschappen (zie
aansluitschema).
6) Voorkom mechanische schokken gedurende het transport en het inbouwen.
7) Voorkom magnetische velden dicht bij de meter. Sterke magnetische velden kunnen de
metrologische eigenschappen van de meter beïnvloeden.
8) Voorkom dat de pluggen en kijkglazen ongeoorloofd geopend kunnen worden in
verband met beïnvloeding van de metrologische eigenschappen en diefstal van gas.
9) Fixeer het telwerk middels de twee M5 bouten aan het voordeksel en verzegel de
afdekplaten.
10) De conditie van de meter kan worden gecontroleerd door regelmatig het drukverschil
te meten over de drukmeetpunten (PM - vs. P punt). Het wordt daarom aanbevolen het
drukverschil over een nieuwe meter te meten. Deze waarde kan worden vergeleken
met toekomstige metingen.
alle BLAUWE of TABLET zegels zijn ‘Metrologische Zegels’;
verwijder deze NIET!
alle ORANJE zegels zijn ‘Service Zegels’; deze kunnen/mogen
worden verwijderd/vervangen.

Introduction to the universal index
This is the standard version and it has two 8-digit mechanical roller
indexes. Depending on the flow direction, one index will be covered.
The index can be rotated in any position, so that the meter can be
used in any position. Two separate LF pulse signals can be
monitored by a integrated male binder connection in the index.
Introduction to the basic index
Optional is the basic index. This is a simplified version of the universal
index. It is suitable for only one flow direction. It is equipped with a
male binder to monitor the LF pulses.
Introduction to the instrument drive
This is a standalone unit to provide a mechanical input into for
example a volume corrector. To rotate the instrument drive, see
instructions below.
Rotating the index
To rotate the Universal index or the instrument drive it is required to remove the two M5 screws.
Therefore the service sealing will have to be removed. After the index has been rotated in the correct
position, the two M5 screws should be mounted and the service sealing will have to be applied again.
(Note: The position of the M5 screws may vary due to customer standards.)
The basic index can always be rotated in the desired position.
