Process Control

Bios products are at home in the diverse process measurement community. From semiconductor to pharmaceutical manufacturing, and from automotive to aerospace production, Bios products help the world's best companies to build better products. With their simple operation, primary and repeatable results and broad flow ranges, Bios products enable industrial process control customers to refine their gas-dependent processes, leading to improved yields and enhanced quality control.

The Definer™ 220 primary flow meter represents a new age for flow meter technology. Now you can do the job of a thermal mass flow meter – but with Proven DryCal Technology. The Definer 220 is a true primary standard that’s based on the principal of volume displacement. Because it’s volume-based, the Definer 220's accuracy is both percent of reading and gas-independent, which means you get accurate, repeatable results without worrying about common thermal flow meter (TFM) issues, such as sensor factors or the subtle viscosity characteristics of the gas being measured. And, it’s handheld, battery-powered design is as rugged as it is reliable, making the Definer 220 equally at home in the lab, on the shop floor or in the field.

For your higher-accuracy process needs, the Bios Met Lab Series represents the finest in primary gas flow measurement. Its true field-portability combined with its measurement speed nets you even more out of its high-precision – you’ll be monitoring more industrial processes than ever before. Sporting broad flow ranges from 5 to 50,000 scc per minute at 100:1 turndown, and measurement uncertainties as low as ±0.15% of reading, the most critical and elusive processes can now be verified, on-site and in virtual real-time.

And there’s more. The Bios gas flow measurement solution combines the best of our high-speed primary piston provers, the Met Lab Series, with the Integrator 110, a simple-to-use universal mass flow meter and mass flow controller command, control and readout device. Combined, these systems integrate seamlessly to provide you with the ability to generate setpoints and read most thermal flow devices, while verifying the results against your Met Lab.

Our Proven DryCal® Technology for process control is accredited to the calibration laboratory quality and proficiency standards set forth by ISO 17025, ANSI Z-540 and NIST Handbook 150, through the National Voluntary Laboratory Accreditation program (NVLAP) of the National Institute of Standards and Technology (NIST).
