Sierra Instruments launches the qMix gas mixing software package, now included with every QuadraTherm 640i/780i thermal mass flow meter on a beta trial basis. The qMix software package is a feature of the smart interface program (SIP).
qMix allows the user to create custom gases or gas mixtures to compensate for gas compositional changes in the field. The qMix can be used when the gas composition changes in a pipe or when moving the meter to another location with a different gas composition. Users can retain accuracy without returning the thermal mass flow meter to the factory. In industries such as biogas or oil and gas, where gas compositions change over time, the meter will not need to go back to the factory for gas recalibration every time gas changes, according to the company.
