A turbine gas meter measures gas velocity with a bladed rotor and converts the rotor speed into volume.

It suits high, steady flows in transmission lines, city gates, power plants and heavy industry. The IM-TM covers 8 to 6,500 m³/h at design pressure up to 100 barg, in aluminium bodies DN50 to DN200 and carbon steel bodies DN50 to DN300, for gas networks and industry in Saudi Arabia and the GCC: the UAE, Qatar, Kuwait, Bahrain and Oman.

How to choose a turbine gas meter

  • Flow and rangeability

    Lowest and highest normal flows must fall inside the range: the IM-TM offers rangeability up to 1:20 from G40 to G4000; for loads that drop low for long periods, compare the IM-RM rotary meter (1:250).

  • Body for the pressure

    Aluminium bodies: up to 8 inch for 20 bar. Steel bodies: up to 12 inch for 100 bar. Flanges: ANSI 150, 300 or 600 to ASME B16.5, or PN16 to PN100 to EN 1092-1.

  • Temperature range

    The flyer gives an ambient range of -40 to +65 °C and a gas temperature range of -25 to +55 °C.

  • Installation space

    A multi-stage flow conditioner built into the meter body removes swirl and turbulence before the rotor, so the technical brochure allows a minimum straight upstream section of 2 DN at compact stations.

  • Removable cartridge

    The removable metrological cartridge lets you change capacity or carry out maintenance by swapping the cartridge.

  • Custody transfer and outputs

    For custody transfer, the IM-TM is designed to EN 12261 and certified under MID, PED and ATEX, with an 8-digit index, low frequency pulse outputs and optional high frequency sensors for a Modus volume converter.

  • What to send us

    For power plants in Jubail, booster stations near Dammam or a city gate in Doha, send us the flow, pressure and flange class.

Frequently asked questions

Why does a turbine gas meter need a flow conditioner?

Rotor speed depends on how the gas reaches the blades, so swirl and turbulence from upstream pipework can disturb the reading. The IM-TM integrates a multi-stage flow conditioner and places the turbine wheel at the rear of the cartridge, which doubles the straightening length compared with conventional turbine meters. The brochure gives a minimum straight upstream section of 2 DN.

Should I choose a turbine meter or an ultrasonic meter?

It depends on line size and duty. The IM-TM turbine meter covers 8 to 6,500 m³/h up to DN300, with rangeability up to 1:20 and a removable cartridge. The FioSonic ultrasonic meter has no moving parts, goes up to DN750, offers rangeability up to 1:125 for custody transfer and gives path-by-path diagnostics. We can compare both on your flow and pressure data.

Can the IM-TM be used with hydrogen blends?

Yes. The IM-TM is biomethane compatible and rated for natural gas blends with up to 25% hydrogen in both aluminium and steel bodies, with higher blends on request. A dedicated 100% hydrogen version, the IM-TM H, is also available for lines that carry pure hydrogen.
