The QUANTIM&reg Coriolis family of products provides users with precise measurement and control of liquids and gases at lower and higher flow rates. A modular hardware platform using improved sensing tube geometries and optical sensing techniques now enable QUANTIM to handle both liquids and gases. This new platform allows QUANTIM to measure and control flows as low as 1 g/hr (gram per hour) and as high as 28,000 g/hr. Controller features a new valve that is more forgiving of variations in line pressures and reduces the chance of clogging due to a larger orifice. The new valve also uses an all-metal valve seat thus eliminating potential control issues associated with elastomer valve seat compatibility and swelling. Users can change liquids or gases without switching meters or recalibrating the device. QUANTIM has no moving parts in the area where process liquids and gases flow, which minimizes maintenance requirements. Minimal physical space is required due to its small, integrated design. Piping and wiring during installation are dramatically simplified since QUANTIM has fully integrated sensor, transmitter, valve, and control electronics.
