  • Counting device is in a gas-free space
  • Low starting value
  • Pressure extraction connection inside the meter
  • Designed for simple servicing (measurement-cartridge principle)
  • Standard integrated flow strainer
  • Short straight inlet lengths (2 × DN)
  • Operation temperature range:
    - gas temperature -10°C up to +60°C
    - ambient temperature -10°C up to +60°C

Options

  • Pulse generator:
    - 2nd LF-IPG, 1x can be retrofitted without breaking the verification seal
    - MF-IPG

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
  • Type Examination Certificate FTZÚ 15 ATEX 0172X
  • Marking of equipment Ex II -/2G IIB T4

Corrosion / Guarantee

All components of the special version designed for bio and sewer gas have  a surface treatment, a so-called passive corrosion protection (surface treated monopipe adaptors available on request).

For the operation of EQZK with sewage gas we cannot grant any warranty of durability as the chemical condition of the gas has an important influence to the working life of the meter.

Factors as:

  • sulfurated hydrogen
  • humidity
  • dirt
  • dew point of gas lead often to an unknown aggressiveness of the gas

Ammonia in the sewer gas attack all nonferrous metals. Therefore, all surfaces of meter parts in contact with the biogas are PTFE-coated (Teflon).
