Sierra Instruments designs and manufactures high-performance thermal mass flow controllers, immersible thermal mass flowmeters, vortex flow meters and transit-time ultrasonic flow meters for nearly every gas, liquid, or steam application.
Gas Flow Meters & Controllers for Accurate Mass Flow Measurement
Sierra designs and manufactures a wide range of today's most advanced analog and digital gas flow meters, mass flow meters, controllers and switches across three core technologies: Capillary Thermal, Immersible Thermal, and Mass Vortex. Each gas flowmeter or controller meets exacting standards, and we can also customize your flow rate sensor to meet application requirements (often free of charge).
Ultrasonic Meters, Volumetric Vortex Meters and Flow Switches for Liquids
Measure liquid flow rates quickly and more accurately with Sierra transit-time ultrasonic flow meters, vortex flow meters or thermal flow switches. Manufactured by Sierra’s team of flow engineers, our liquid flow meters are suited for even the most challenging liquid flow applications.
Vortex Volumetric and Multivariable Flow Meters for Saturated & Superheated Steam
The ideal technology for steam flow measurement, the InnovaMass vortex steam flow meter measures five process variables with one process connection: mass flow, volumetric flow, density, pressure, and temperature. With five high-accuracy results available from a single device, total cost-of-ownership plummets while still providing accurate steam flow meter rates. Lower initial cost, less complex installation, and reduced maintenance costs contributed to significant overall savings to maximize your steam productivity.
