MQM TURBINE GAS FLOW METER (QUANTOMETER)
MRM ROTARY DISPLACEMENT GAS METERS - MID & OIML APPROVED
M
RM Turbine gas flow meters are now available in the UK exclusively from Bell Flow Systems. Manufactured by
Metreg Technologies who offers a complete product range for fiscal and non-fiscal gas flow measurement for industrial and commercial applications. The MRM rotary displacement gas flow meter is designed for
fiscal metering of natural gas and is approved according to the European requirements of EN12480, MID (2004/22/EG) and OIML R137-1 & 2: 2012. The MRM rotary displacement gas meter is suitable to be installed in hazardous areas of Category 2 (Zone 1) II 2 G c IIC T4 X. The MRM rotary displacement gas meter is suitable for the following gases: Natural gas, town gas, propane, butane, ethylene, air, nitrogen, with further gases on request. Rotary gas meters are characterized by their very compact
design and high accuracy. The MRM rotary meter requires no inlet or outlet straight pipe lengths or flow conditioning and is insensitive to severe gas flow fluctuations (discontinuous operation). The rotary meters MRM are manufactured with large measurement ranges due to the precision machining of the parts and a very reproducible assembly process. The standard calibrated measurement range for the MRM is 1:50. Extended measurement ranges up to 1:200 are optionally available according to approved and certified measurement ranges as shown in the table.

QM Turbine flow Meters are now available in the UK exclusively from
Bell Flow Systems. Manufactured by Metreg Technologies who offers a complete product range for fiscal and non-fiscal gas flow measurement for industrial and commercial applications. MQM wafer style Gas turbine flow
meters are ideal for commercial and industrial applications for non-fiscal measuring of natural gas in pipe sizes from DN50 up to DN150 and larger. Offering a range of wafer styles, these aluminium meters are ideal for secondary metering or in-process measurement. They offer high accuracy and a choice of calibration options. They are mainly used for internal measurements or control tasks. The MQM Quantometer is based on the
principle of a turbine flow meter. The flow of the gas to be measured causes the turbine rotor to rotate. The gas flow is narrowed on an annular cross section, is accelerated and directed onto the smooth-running Aluminium rotor. The number of rotations is proportional to the measured gas volume; the frequency of rotations is proportional to the actual gas flow. The rotation of the rotor is connected to a speed reducing gear train and transmitted via a magnetic coupling from the gas pressurized area to the adjustable 8 digit roller counter fitted to the outside of the meter The MQM Gas Meter is suitable for
installation in hazardous areas of Category 2 (Zone 1) II 2 G c IIC T4 X. It is designed for flow and volume measurement of non-corrosive and non-

aggressive gases like natural gas, nitrogen, air (and other gases on request) in non-custody transfer and process applications. The MQM is available in sizes from DN 25 (1´´) to DN 150 (6´´) with a volume flow rate up to 1600 m3/h depending on meter size. The lifetime durability of the MQM
Quantometer is very stable due to the large dimensioned high precision ball bearings “Made in Germany” along with the high precision machining of the body and all moving parts. All MQM Quantometers are equipped with precision machined Aluminium turbine wheels. After machining all Aluminium parts, especially the turbine wheel, are hard anodized for reduced friction and higher resistance to mechanical wear and tear or chemical attack. In case of contamination or dust in the measured gas it is recommended to install an optional oil lubrication pump for increased operating life. During installation and commissioning a temporary Top Hat or Cone filter should be installed to prevent meter damage. The Quantometer is a turbine gas meter
and registers the actual volume with an eight-digit mechanical roller counter. Utilizing the LF of HF pulser (reed contact) the volume pulse output sensors allow for remote monitoring, data recording and linking with Building Management Systems (BMS) as well as with gas volume correctors (EVC's) and our ATEX telemetry systems.

The MRM rotary gas meters show very stable and reproducible
measurement results. The design of the housings and pressure containing parts has been optimized especially for outstanding operation, even under challenging torsional and bending stresses. The meters can withstand more than twice the specified torsional and bending stresses after installation as defined in EN 12480. The lifetime durability of the MRM rotary gas meter is very
stable due to the large dimensioned high precision ball bearings “Made in Germany” along with the high precision machining of the body and all moving parts.
