Coriolis flowmeters help GF reduce filling times and improve accuracy 08 June 2012

GF is reporting reduced filling times, improved accuracy and repeatability and tighter filling tolerances on its filling machines since installing the latest Micro Motion FMT filling mass transmitter, from Emerson Process Management.

Based in Parma, Italy, GF designs and manufactures high-tech filling equipment and control systems for the pharmaceutical, medical and food industries – typically for the precision measurement of injectables, infusions, ophthalmic preparations, syrups and detergent solutions.

"Emerson's Micro Motion Coriolis technology is accurate, reliable and user-friendly, adding value for our end user customers," comments Marco Serventi, sales manager with GF.

Previously, GF had been using filling systems based on time-pressure instruments, as well as piston-syringe and peristaltic (roller type) pumps, for the pharmaceutical industry, he explains.

Apart from improving the speed and accuracy of its machines, and enable users to change media without replacing the instrumentation, GF wanted to enable in-line sterilisation without disassembling the machine.

Serventi says GF met these objectives by using the FMT filling mass transmitter with Micro Motion Elite and H-Series flowmeters.

Specifically, GF has improved system response time and reduced batch cycle times by taking advantage of integrated valve control from the transmitter, rather than the traditional pulse output, set up through a PLC.

In addition, the rangeability of the Coriolis flowmeter allows different media to be dispensed without changing any mechanical components. For example, fillings can be in the range from 0.5g to 5Kg.
