The Definer™ 220
Now more than ever, modern industry requires precisely-honed process control systems. Requirements, standards and competition have become so demanding, and the margin for error so slim, that for many organizations, ±2% or ±3% of reading standardized accuracy is no longer enough.
They need more. They need the dependable Definer™ 220 primary flow meter.
The Definer 220 allows users to verify gas flow rates, in the field or in the lab, to an accuracy of ±1% percent of reading, including temperature and pressure compensation. Unlike thermal mass flow meters, the Definer 220's positive displacement technology provides immediate indication of actual volumetric gas flow rate – accurately and independently of gas type. Integrated temperature and pressure sensors in the flow stream allow users to automatically standardize volumetric flow readings to standard conditions, for traceable verifications of mass flow devices.
The Definer 220 represents the next generation of our Proven DryCal® Technology developed specifically for critical industrial and environmental applications. It comes standard with Bios Optimizer™ 110 standalone software and provides the accuracy, customization and durability needed in today’s exacting, fast-paced workplace.
