Sierra

Sierra Instruments manufacturers high performance mass flow meters and mass flow controllers for nearly any gas, liquid, or steam application. Thermal Mass, Transit-Time Ultrasonic, Vortex Shedding and Multivariable flow meters are available in both standard and customized versions for applications in laboratory, industrial, and hazardous environments. Sierra's flow measurement technologies precisely measure or control very low flows down to less than 1 sccm full scale as well as extremely high flows of gas, liquid, and steam.
