  INTRODUCTION

  The FMG series of rotary gas meters are designed to meet the highest demands of reliable and accurate measurement of gas flow.The meters are MID approved and fully comply with EN 12480 and OIML R137.The compact exchangeable aluminium cartridge allows local repair and on-site cleaning.Therobustdesign of the casing and the cartridge make the meter less sensitive to installation stresses caused by the connecting piping. A significant amount of misalignment of the connecting piping/flanges can be tolerated by the meter without affect- ing the meter performance by jamming the impellers.

  The aluminium casing of the FMR (body and front plate) is designed for working pressures up to 20 barg with a safety factor of 4. The square impellers and the improved position of the main bearings and shafts, make the meter less sensitive to overload and pressure shocks. The aluminum index and the protection of the LF pulsers with the associated magnets, make the meter less sensitive for manipulation by externally applied magnets or other external forces. Tampering of meters with strong neodymium magnets is one of the major concerns of utility companies, as this kind of manipulation is very difficult

  to detect or prove. In order to be prepared for the “smart grid”, the index can also be equipped with an intelligent encoder.
  The unique proprietary oiling system, where the oil is distributed directly to the timing gears by means of a disc, eliminates oil loss at high rotor speeds and will lubricate the timing gears at very low loads. All plugs and oil sight glasses are in the front of the meter, allowing the meter to be installed in very compact installations.

  PRINCIPLE

  The FMG rotary gas meter is a displacement type gas meter. The actual measurement is performed by two figure 8-shaped impellers (rotors) rotating within a measurement cham- ber. During a full revolution of the rotors a fixed volume is displaced from the inlet to the outlet of the meter. The number of rev- olutions represents the amount of volume passed. The volume is displayed on a direct read counter type index. Several low and high frequency pulsers can be used for flow computing or control purposes.

  APPLICATIONS

  The FMR series of rotary meters is suitable for custody transfer gas measurement of all non-corrosive gases such as natural gas, propane, butane, air, hydrogen, etc.
  Typical applications are:

  • Gas distribution in low,medium or high pressure networks • Industrial applications
  • Master meters for test benches

  Special constructions can be supplied for use under extreme conditions like higher temperatures and corrosive gases.

  ACCURACY

  Each FMR rotary meter is tested with atmospheric air to traceable (according to MID) calibrated references. It has been proven – as part of the type approval testing – that the difference between the accuracy at atmospheric air and at high pressure natural gas is negligible.

  TYPICAL METROLOGICAL CHARACTERISTICS

  Accuracy Qt to Qmax:	± 1% or better
  Accuracy Qmin to Qt:	± 2% or better
  Repeatability:	better than 0,1%

  PRESSURE LOSS

  The average pressure loss of the FMR rotary meter using atmospheric natural gas with a relative density of 0.6 is measured at one (1) diameter upstream to one (1) diameter downstream of the meter on straight pipe of the same size as the meter. The pressure loss across the FMR rotary meter for various gases and other operating pressures may be approximated from the pressure loss equation.

  CARTRIDGE DESIGN

  All FMR meters consist of an aluminium cartridge inserted in a meter body. The cartridge can be removed and inserted with the body remaining installed This allows local repairs such as replacement of the main bearings and on-site cleaning to be carried out without removing the meter body. Particular owners of older networks, suffering from dirt and/or condensate, will benefit from the ability to remove the cartridge. FMG has a cartridge exchange program to replace older cartridges with new calibrated ones..

  SUPERIOR METROLOGICAL PERFORMANCE

  Starting with the G40, all meters are approved according to both EN12480 and OIML R137/1 for rangeabilities up to 1:160 and as such can, on request, be designated as Class 1.5 meters. In situations where the installation or gas conditions are severe, the risk of rejection is greater when recalibration is done against in-service tolerances. The designation of class 1.5 (instead of 1.0), while still maintaining the class 1.0 accuracy limits, could be of interest since the in-service tolerances of a class 1.5 meter are significantly larger than the class 1.0 tolerances.

  SQUARE IMPELLER TECHNIQUE

  The use of square impellers not only makes the meter very robust and short, but also improves the accuracy and rangeability. The unregistered leakage causing an error at minimum capacity, thus limiting the rangeability, is significantly smaller for square impellers (shorter profile) compared to the traditional long impellers.

  PREPARED FOR THE FUTURE

  The FMR series use a fix gear ratio in the index (no adjustment gears in the index).
  The index is connected to the meter body by means of a special bayonet connection. After removing the main seal (allowed under supervision of the local authorities or accredited laboratory), the index (and as such the functionality of the meter, like number and type of sensors, magnetic protection, smart communication, electronic display, etc.) can be changed in a matter of minutes. This unique feature makes the FMR series of rotary meters future proof.

  ROBUST CONSTRUCTION

  In the new cartridge FMR design, the impellers, timing gears and bearings are fixed and positioned by a synchroplate. Since this synchroplate is machined in one operation, the tolerances can be controlled and maintained at a very high level. As a consequence, the clearance between the impellers and the meter body is equally divided and as such maximized, making the meters less sensitive to dirt and debris. The short impeller and high strength shaft connecting the timing gear to the impeller overcomes flexing or bending of the impellers, hence the meters are less sensitive to flow and pressure shocks. Severe intermittent on/off applications are typically handled without damage. Temporarily overloading the meter up to 50% of the maximum capacity will not cause any degrada- tion of the metrological quality.

  BASIC INDEX

  The basic index consists of a UV-resistant polycarbonate cover glued to an aluminum frame. The aluminum frame will give strength to the index and as such sufficient protection against mechanical interference (Tampering). The index is 100% sealed (IP67) by multiple layers of glue. The index can be rotated over 360° for flow directions right-left, left–right and top-down. The index is equipped with multiple LF switches and normally closed tamper contacts.

  UNIVERSAL INDEX (STANDARD)

  The extremely strong double walled, aluminum, index is designed to withstand any external interference. To protect against large forces applied to the index window, an additional glass window is mounted beneath the polycarbonate window. This glass window will break in case excessive force is applied to the index. On request the index can be sealed up to IP67. Four slots in the outer extrusion can be used for various add-ons such as multi- ple connectors, additional outgoing shafts, marking plates with bar codes, etc. The use of slots makes the index multifunctional and as such “prepared for the future”.

  OPTIONS FOR INDEXES AND INSTRUMENT DRIVE

  The index or instrument drive can be equipped with several options making the meter prepared for the future:

  Magnetic Field Protection: Tampering of meters with strong neodymium magnets is one of the major concerns of utility companies, as this kind of manipulation is very difficult to detect and / or prove. The LF pulsers and its driving magnet can be shielded to overcome tampering with an exter- nally applied magnetic field. Magnetic fields up to 500 mT will not have an effect on the pulse counting..

  Wiegand Pulsers:

  the Index can be equipped with multiple Wiegand pulsers. The Wiegand pulsers have significant advantages over the traditionally used Reed contacts. Wiegand sensors do not face “bouncing” problems and the actual live time is not limited as much as the traditional Reed contacts.

  Intelligent Index/Encoder:

  the index can be equipped with an intelligent encoder. The encoder
  sends out the total volume with an interval of 400 msec. The encoder
  uses a standard NAMUR serial data format, and can be modified to special applications on request. The encoder is powered by one AA cell battery guaranteed for 12 years of operation. On request two AA cells can be installed for a guaranteed life time of 20 years. The encoder is equipped with a special Hall sensor to detect and register interferences from external magnets. Several programmable inputs/outputs are available for advanced anti-fraud functions.

  HIGH FREQUENCY PULSERS

  Our rotary meters can be equipped with a high frequency sensor. Unique is the fact that the high frequency sensor generates two independent phase shifted signals and as such the flow direction can be monitored.

  TAMPER PROOF

  All plugs, sensors and oil sight glasses can be sealed (wire) and as such the meter is not vulnerable to tampering. If, for example, the oil compartment was accessible, the metrological performance could be changed (increasing or decreasing mechanical friction) by changing oil properties. In addition to the me- chanical precautions, the index can be equipped with an intelligent encoder, recording time stamping of all attempts of unauthorized access or manipulation, such as magnetic interference, reverse flows, etc.

  DOUBLE INTEGRATED THERMOWELLS

  The rotary meters are equipped with two integrated thermo wells.
  Having two thermowells, the verification of Electronic Volume Conversion Devices (when built on to the meter) can be done on site and online with- out interruption of the operation. By comparing the reading of EVCD tem- perature sensor with a calibrated temperature sensor or one of known accuracy placed in the second thermowell, the EVCD can be verified.

  INSTALLATION

  Installation of rotary meters can be horizontal or vertical. Since the meter is designed for multi position, consideration need only be given to the arrows showing the flow direction. After the meter is installed, the index can be rotated to the correct position. The index can be rotated over 360°. The rotary meters can be metrological sealed to suit various conditions from total flexibility to highly tamper proof.

  The FMR DN50 meters are also available with a length of 150mm to exchange for DN50 (2”) turbine meters.

  MAINTENANCE

  The rotary gas meters have a rotating disc for distributing the oil directly to the timing gears. The mechanism is designed to prevent oil loss at high loads or from pressure variations and maintains sufficient oiling at low flows. Since the oil system operates between 40% and 120% of the maximum flow, sizing of the installation is no longer critical. The oil supplied with the meter is suitable for 10 years of operation under normal conditions.

  CLEANING / EASY REPAIR

  After removing the front cover of the meter, the entire cartridge can removed for cleaning. During this cleaning process, the meter body can remain in line. For cleaning purposes the seals of the front cover have to be removed. The construction of the FMG rotary gas meters allows local repair or replacement of all the main bearings without special tools. If the main bearings are to be replaced, the critical timing of the impellers will be maintained.

  It is recommended that replacement of the main bearings (mounted in the synchroplate) is performed by a skilled technician in a clean environment. The rear bearings can be replaced with the meter body in situ. In a situation where a meter is locked by dirt, the cartridge can be removed for cleaning. The use of a cartridge (pre-calibrated) and the accessibility of the front and rear bearings without the need for removing the timing gears, make the FMG series of rotary meter unique in terms of repair. Any repair shop can repair or re-condition the meters without special skills and tools. When regulation permits, a new, calibrated cartridge can be installed.

  EVCD MOUNTING

  The rotary meters are equipped with two thermo wells and two pressure tapping points. Therefore the rotary meters can be supplied with an Electronic Volume Conversion Device (EVCD).

  FMR-DUAL SERIES (PULSATION FREE)

  Turbine meters have a limited range and must preferably be calibrated close to the operating conditions (high pressure natural gas). This limitation and the higher costs due to the calibration, make the larger rotary meters more popular as replacement for the turbine meter. To overcome the drawback of conventional rotary meters (pulsations and resonance), pulsa- tion free rotary meters have been developed. These pulsation free rotary meters, using two phase shifted pairs of impellers, fully eliminate the pulsa- tions by countering the characteristic sine wave and its resultant resonance. As a result the pulsation free rotary meters series DUAL are extremely quiet and accurate.

  Another advantage is the use of relatively short impellers. Shorter impellers will not deform easily and as such provide reliable long term performance. The weak point of pulsation free meters can be the connection of the two impeller pairs as this mechanical coupling is very sensitive to load differenc- es between the two sets of impellers. The DUAL meter uses a significantly stronger spline and spline shaft to connect the two pairs of impellers.

  EXCHANGEABLE FLANGES

  By using exchangeable flanges, the installation connection of the meter can easily been changed from DIN to ANSI or from DN100 (4”) to DN150 (6”).

  FMR SERIES FOR PRESSURE UP TO 30 BAR

  The rotary meters are developed with an optimized body construction. Due to the special design and the strength of the aluminium construction the rotary meters can be used with higher pressures. Since this develope- ment has been done as an optimization for the standard aluminum bodies there is no need of a steel body for pres- sure upto 30 bar.
  The aluminum bodies are being provided with a special treatment to increase the strength but still maintain their low weight.

  FMR-HP SERIES (FOR PRESSURES UP TO 100 BAR)

  The FMR-HP series of rotary gas meters is designed to meet the highest demands of reliable and accurate measurement of gas flow under high pressure conditions. The meters fully comply with the EN12480 and OIML R137 and as such can be used for all custody transfer applications.

  The actual meter body is made from aluminium and is kept in position by a steel meter housing. This housing holds the meter body, without any stress, in position between the adjacent flanges. Since the meter body is not affected by stress from the flanges or
  the piping, the clearances between the impellers and the body are optimized. As such the superb metrological performance achieved in the low pressure rotary meter is maintained under high pressure conditions as well.

  Due to the large rangeability of 1:100, the FMR-HP rotary meter is very suitable for small city gate stations as the actual load of this type of station varies widely. Square impellers and improved position of the main bearings makes the cartridge very robust and less sensitive to flow and pressure shocks. Unlike other approved
  flow metering devices, such as turbine meters and ultrasonic meters, a rotary meter can be installed close to regulators and without the need for extended straight pipe or specially prepared inlet sections.

  BYPASS FOR SECURITY OF SUPPLY

  The FMR-HP series can be equipped with a spring loaded bypass valve. If a meter locks, the differential over the bypass valve will increase and the valve will open allowing gas to pass. This security of supply feature makes the FMR-HP suitable for use in critical installations where gas flow cannot be interrupted. The opening of the bypass can be monitored by measuring the differential over the meter.

  EXCHANGEABLE CARTRIDGE

  A compact exchangeable aluminium cartridge allows local repair, on-site cleaning and exchange. A pre-calibrated cartridge can be exchanged without affecting the accuracy. To access the cartridge only a relatively small and light weight cover needs to be removed.

  METER BODY DESIGN

  To maintain the high accuracy and large rangeability, it is essential that the displaced volume does not change within the range of operating conditions.
  By separating the meter body from the actual pipeline and using the same material as the impellers, changes in displaced volume due to installation stresses, operating pressure and thermal expansion are eliminated.
