MRM ROTARY DISPLACEMENT METER – MID & OIML Approved

Metreg Technologies offers a complete product range for fiscal and non-fiscal gas measurement for industrial and commercial applications. Metreg measuring devices stand out thanks to their high precision and robust design with each meter being individually calibrated and tested to approved and international standards on traceable flow and pressure test benches.

The different types of Metreg gas meter can all be fitted with various low, medium and high-frequency pulse outputs. All devices can be connected to various electronic ancillary devices such as Electronic Volume Converters (EVC’s) remote ATEX flow displays, data loggers and data telemetry devices for monitoring and reporting.

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.

 

 

 

 

 

 

 

 

 

 

 

 

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. After machining all Aluminium parts are hard anodized for reduced friction and higher resistance to mechanical wear and tear or chemical attack. 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.
