TRZ2 Turbine Flow Meter

TRZ2 Fiscal flow meter with axial turbine for natural gas
Measuring range Up to 1600 m³/h
Process temperature Up to 70°C
Signal output Pulses Reed + NAMUR
Process pressure Up to 100 bar

Approved according to the MID regulations for fiscal measurement, the TRZ2 turbine gas meter offers exceptional features to ensure precision and reliability. It complies with the EN12261, PED, ASME, ATEX, and IECEx standards, providing the lowest measurement uncertainty and high repeatability.

Equipped with an aluminum flow straightener, the meter ensures precise measurements in a wide range of applications. It is available in various sizes from G65 to G1000, with a maximum measuring range of 5 to 1,600 m3/h. The nominal diameters range from DN 50 to 150 (2" to 6"), supporting operating pressures from 0 to 100 barg, and flange ratings in PN 10-100 and ANSI 150-600.

The TRZ2 turbine gas meter is designed and manufactured in accordance with the European Standard for turbine meters EN 12261. As a standard, the TRZ2 meets the error limit requirements of EN 12261, which are as follows:

  • ± 1 % for the flow from 0.2 Qmax to Qmax
  • ± 2 % for the flow from Qmin to 0.2 Qmax.

The revolutions of the turbine are transmitted to the 8-digit mechanical counter located in the pressure-less index head through gears and a magnetic coupling. Finally, the outlet of the meter is designed for optimal flow conditions and reduced pressure loss after the measurement process. For enhanced functionality, the meter optionally offers NAMUR high-frequency pulses.
