Page 6: Declaration
3. Declaration Declaration of Conformity (Annex A) 4. Use and Scope The turbine meter MTM is designed for fiscal or in-plant metering of natural gas and approved according the European requirements of EN12261. The MTM turbine meter is suitable to be installed in hazardous area of Category 2 (Zone 1) II 2 G c IIC T4 X. The MTM turbine meter is suitable for the following gases: • Natural gas, town gas, propane, butane, ethylene, air, nitrogen, noble gases • Hydrogen (with reduced measuring range) • conditioned biogas acc. DVGW G260 for combustible gases • Further gases on request. The MTM turbine meter cannot be used for: Oxygen, Acetylene and other aggressive gases as well as for explosive gases or gas mixtures. The meter should not be used in applications with the presence of strong pulsations. -

Page 9: Mounting Position / Direction Of Flow
• The gas should be dry. If condensate may be occur then the installation of a condensation trap upstream of the meter is recommended (in some filter types it is integrated). In this case choose Flow direction from top to bottom Do Not install the meter at the lowest point of the piping Attention: The MTM turbine meter is not suitable for oxygen and other highly corrosive gases as well as for explosive gases and gas mixtures. 8. -
Page 10: Preliminary Work
9. Preliminary work Before the installation of the meter make sure that the following steps has been observed: Remove the plastic cover sheets at the inlet and outlet of the meter. 2. Inspect the meter for completeness (e. g. plugs, provided oil volume) and for absence of any transport damages. Clean the flange surfaces (e. g. with petroleum). Check by blowing into the meter that turbine rotor rotates easily and stops smoothly. - Page 11 Pressure Flanges according DIN EN 1092-1 [mm] Class PN Hexagon screws and nuts Min. operating srew temperature material material of the screws and nuts 100 - 40°C 25CrMo4 25CrMo4 100 - 40°C 25CrMo4 25CrMo4 100 - 40°C 25CrMo4 25CrMo4 100 100 - 40°C 25CrMo4 25CrMo4 150 100...

Page 12: Lubrication And Maintenance Of The Mtm Turbine Gas Meter
10. Lubrication and Maintenance of the MTM turbine meter Turbine meters with permanent lubricated ball bearings (no oil pump) are maintenance-free. Turbine meters with an oil pump need periodic lubrication. The initial lubrication procedure is: Use only oil recommended and supplied by Metreg Technologies. One set of oil for commissioning is delivered with the meter. Specified oil: Shell Morlina S2 BL 5 or Shell Morlina S2 BL 10 Fill in the oil before commissioning the meter and after the correct installation of the meter described in chapter 7 and 8. -
Page 13: Maintenance Of The Mtm Turbine Gas Meter
2.2. If the gas is carrying dust and/or moisture then the lubrication has to be done at least every month. A repair of the turbine meter has only to be done by competent and authorized personnel like the Service Engineers from Metreg Technologies. Don’t break any seals. If only one of the seals is damaged or broken the meter cannot be used for custody transfer measurements of natural gas according MID (2004 / 22 / EG). 12.

Page 14: Pulse Generators
14. Pulse Generators Two low frequency (LF) pulse generators are plugged to the meter index head in standard delivery. A third low frequency (LF) pulse generator is optional. The function of these three LF-pulsers is: • 1 LF-pulser for flow measurement • 1 additional LF-pulser for flow measurement (option) • 1 LF-pulser as anti tampering contact. - Page 15 The connection of the LF pulse transmitter unit is different depending on whether the meter head is made of composite or aluminum. Index head out of composite: The LF-pulser unit comes standard with three meter cable. The cable configuration is as follows: •...

Page 16: Pressure Measuring Point
15. Pressure Measuring Point There is a pressure test point within the Pressure test point MTM turbine meter as shown in figure 8. The pressure tap is marked with “p ”. The pressure test point is designed for a connection of steel tubing with a diameter of 6 mm. The steel tubing should be according DIN EN 10305-1 and not made of stainless steel or nonmetallic materials like plastics. -
Page 17: Cleaning
17. Cleaning For cleaning the meter from dust and dirt please do not use any solvents. It is suitable to use a damp cloth only for that purpose. 18. Transport and Storage The turbine meter and accessories shall be stored in the original packaging. Secure the measuring device from rotating or slipping. Be careful during loading and transportation to or from the measuring point. Some requirements for transportation and storage of the meter are: •... -
