Possibilities for connection and ancillary equipmentImpulse generators, installed in counter housingThis new Aerzen gas meter series is equipped with a low frequency impulse generator model IZ 9 as standard(optional double impulse generator model IZ 9-2). In addition the following impulse generators can be installed:• high frequency impulse generator type IZ 6• low frequency impulse generator type IZ 4• low frequency impulse generator type IZ 8GasmetersizeModelInstalled impulse generatorsMechanical output(Option)Optional impulse generators (Option)installed to output driveInduction switch Reed contact DiodeInduction switch Reed contact Displacement MaximumTyp IZ 4 Typ IZ 6 Typ IZ 9 Typ IZ 8 Ua M maxTyp IZ 10 Typ IZ 11 Typ IZ 50 Typ IZ 51 Typ IZ 111Option Option Standard Option per unit allowableno exapproval[m³/lmp] f bei Q max[m³/lmp] [m³/lmp] [m³/U] [N mm] [m³/lmp] [m³/lmp] [m³/lmp] [m³/lmp] [m³/lmp]G 40 Zc 038.05 0.01 360 Hz 0.1 0.01 0.01G 65 Zc 038.06 0.01 400 Hz 0.1 0.01 0.01G 100 Ze 039.0 0.1 400 Hz 1.0 0.1 0.1G 160 Ze 039.1 0.1 460 Hz 1.0 0.1 0.1G 250 Zc 11.3 0.1 400 Hz 1.0 0.1 0.1G 400 Zc 11.4 0.1 440 Hz 1.0 0.1 0.1G 650 Za 13.f7 0.1 250 Hz 1.0 0.1 0.1G 1000 Za 13.8 1.0 280 Hz 10.0 1.0 1.0G 1600 Za 15.11 1.0 170 Hz 10.0 1.0 1.0G 2500 Za 16.f13 1.0 120 Hz 10.0 1.0 1.0G 4000 Za 16.13 1.0 170 Hz 10.0 1.0 1.020.001oder 0.010Technical data sheets 4 SZ-372 4 SZ-376 4 SZ-377 4 SZ-2915200.010or0.100.10or1.00,01 x Ua up to 100 x Ua0.0100.101.00,1 x Ua up to 100 x Ua0,0005 x Ua up to 1 x UaImpulse generator, installed at mechanical output driveIn addition to the impulse generators installed another impulse generator can beinstalled - in accordance with the chart by means of the mechanical output drive.output drivelocationMechanical output driveAll meter sizes can be operated with a mechanical output drive without limitationto the measuring ranges!For connection of additional equipment a mechanical output drive is available exfactory or can be retrofitted at site under supervision of a calibration inspector. Theconnection sizes for the accessories correspond to DIN 33800, which has been theAerzen standard since 1951.The values of rotation and admissible connection torques are shown in the abovechart. The mechanical output drive can be used e.g. for installation of the followingequipment, observing M max.• impulse generators (see chart)• mechanically driven volume converters• electronic compact converters (other makes)• encoder counterOptional accessories• for temperature measurement thermowells in different threads are available( G¼ / G½) – please also refer to drawing 4 SZ-464.• for protection against impurities optionally starting strainers in different designs(conical strainers – drawing 3 SZ-242 and filter screen – drawing 4 TZ-802)are available.• encoder counter on request8Mechanical output driveConnection dimensions perDIN 33800 (shown for U a= 0,1 m 3 )
Suggestions for connecting accessoriesAll the usual measuring tasks encountered in the public gas distribution industry canbe accomplished by using the impulse generators to be installed in the counter or viathe mechanical output drive - please refer to page 8 -. In addition the high frequencyimpulse generators allow for accurate indication of the instantaneous value (e.g. m 3 /h),as it is used for vehicle diagnostics. Here some examples:Impulse transmissionfrom IZ 9 or IZ 9/2Impulse transmission of the optionally installedimpulse generators (see page 8)Shown for gas meter sizes G 40 to G 400(For gas meter sizes G 650 to G 4000 -temperature connections provided in the pipe)Pressure transmission, G¼G¼ for temperature control measurementG½ for temperature measurementManual checking deviceAfter removing the lockingscrew (sealed), when thegas meter is at standstilland de-pressurized, theease of rotation of thepistons can be checkedmanually by using a boxspanner. Useful duringinstallation and to diagnosemalfunctions.Pressure transmission, G¼9
