The temperature transmitter is required when a flow converter or flow computer is used to convert the measured volume to base conditions, in some countries called standard or normal conditions. The temperature sensor should be installed in a thermo-well.

As an option, your IGTM Gas Turbine Flow Meter can be equipped with an integrated thermo-well. Alternatively, the temperature measurement shall be located downstream of the meter. vemm tec recommends 1 to 3 meter diameters distance downstream from the meter, but not more than 600 mm. No pressure drop should occur between the temperature device and the meter. The temperature sensor is recommended to be within the center third of the pipe and be protected from heat transfer from the external environment.

A second thermo-well close to the other one may be added to allow in-line checking of the main temperature
sensor.

Some specific models of the IGTM Gas Turbine Flow Meter are equipped with thermo-wells integrated in the meter body. Do not replace these thermo-wells by other models and do not remove these thermo-wells when the meter is pressurized.
