TRZ Radial turbine gasmeter

TRZ Radial turbine gasmeter

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)
