50 YEARS
of Flow Innovation

For Monterey-based Sierra Instruments, 50 years marks the beginning of a new era of global innovation in precision flow measurement where truth prevails as a driving force.

Today, Sierra flow meters regulate greenhouse gases, convert waste to energy, and deliver life-saving vaccines. They control industrial processes and help create silicon chips that enable our everyday life.

After fifty years, a new Sierra team built on core values that never change continue to deliver on a vision of operational excellence.
