Sierra Instruments announces the launch of its new flow energy solution for managing and optimizing flow measurement for industrial facilities of all sizes. It features Sierra's QuadraTherm 640i/780i thermal flow meters, their InnovaMass 240i/241i vortex flow meters, and their new InnovaSonic 207i ultrasonic flow meter. Designed, built, and calibrated in the USA by Sierra, the Big-3TM share the same revolutionary Raptor firmware and many of the same software apps. They are a complete flow energy solution for flows like compressed air, natural gas, steam, and hot and chilled water. Together, they set a new standard in ease-of-purchase, performance, accuracy, reliability, and ease of use.
