The vemmtec IGTM Gas Turbine Flow Meter is a highly accurate flow meter, approved for custody transfer measurement, equipped with electronic pulse outputs and a mechanical counter. This document explains the dimensions, ranges, performance, calibration and outputs of the instrument. It details the installation, safety requirements and material specifications.

The vemmtec IGTM Gas Turbine Flow Meter measures gas volume flowing through an annular passage in the meter. The flowing gas volume is totalised on a local mechanical counter. In addition, low or high frequency pulse signals are generated to infer the gas flow and volume. The indicated gas volume is the actual volume flowing through the meter at the actual temperature and pressure. The IGTM is available in two models: CT and IM.

The vemmtec IGTM Gas Turbine Flow Meter-CT is used for high accuracy and custody transfer applications. The IGTM-IM is an economically priced meter with a good accuracy.

Gas Types

The vemmtec IGTM Gas Turbine Flow Meter in its standard design can be used for all non-aggressive gases, such as natural gas, methane, propane, butane, city gas and fabricated gas, air, nitrogen, etc.

For aggressive gases, like sour gas, biogas and oxygen, special designs are available with Teflon coating, special lubrication or special purging. See table 1, for detailed requirements or different type of gases.

Temperature Ranges

As standard The vemmtec IGTM Gas Turbine Flow Meter is designed to operate at temperatures between -10°C to 60°C. Special low and high temperature designs are available on request.
