Technical characteristics

• Principle of velocity measurement
• For measurements requiring obligatory verification (for MID versions)
• Accuracy:
  - from 0.2 Qmax to Qmax ... +/-1 %
  - below 0.2 Qmax ... +/- 2 %
• Sizes G 16 up to G 400 (for billing G 65 - G 400)
• Dimensions DN 50, 80 and 100
• Operating pressure max. 6 bar
• Meter element can be calibrated without monopipe fitting
• Counting device is in a gas-free space
• Low starting value
• High measurement stability and operational security due to high-quality, wear-resistant components
• Self-lubricating ball bearings
• Pressure extraction connection inside the meter
• Designed for simple servicing (measurement-cartridge principle)
• LF-pulse generator (standard)
• Standard integrated flow strainer
• Short straight inlet lengths (2 × DN)
• Operation temperature range:
  - gas temperature -10°C up to +55°C
  - ambient temperature -10°C up to +55°C

Options

• Over-run brake: Mechanical over-run brake without measuring range for intermitting operation
• Pulse generator:
  - 2nd LF-IPG, 1x can be retrofitted without breaking the verification seal
  - MF-IPG
  - HF-IPG
• Temperature sensor pockets in monopipe fitting

Mounting and maintenance

• Mounting /dismounting of the meter element possible without disconnecting the monopipe fitting
• The monopipe fitting remaining in the pipe network enables mounting /dismounting of the meter element without tension from the pipe network
• Can be installed in any position from horizontal to vertical (turbine axis not suspended and roller counter axis always horizontal)

Norms and approvals

• Developed and produced according to Quality Standard ISO 9001:2008
• International / national type approvals MID TCM 143/13-5110
• Type Examination Certificate FTZÚ 15 ATEX 0172X
• Marking of equipment Ex II -/2G IIB T4
