Sierra Instruments has released a new gas mixing software package that allows users to create custom gases or gas mixtures to compensate for gas compositional changes in the field.

When the gas composition changes in the pipe or when moving the meter to another location with a different gas composition, qMix lets users retain accuracy without returning the thermal mass flow meter to the factory for gas recalibration each time, the company says.

The qMix software package is now included with every QuadraTherm 640i/780i thermal mass flow meter on a beta trial basis.
