Sierra

Your Complete Flow Energy Solution is here.

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.


Applications


Gas

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).

Steam

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 .

UltraSonic - InnovaSonic®

UltraSonic

In addition to gas measurement, many facilities must measure liquid flow energy rates to reduce water bills, determine leakage rates, increase system efficiency, measure thermal energy BTU, and influent and effluent liquid flow. Regardless of the application, Innovasonic clamp-on ultrasonic flowmeters are ideal for liquid flow applications. Clamp-on ultrasonic flow meters achieve high accuracy at low and high flows, save time with no pipe cutting or process shutdown, and are not affected by external noise.

  • High accuracy: +/- 0.5% of reading from 0.16 to 40 ft/s (0.05 to 12 m/s)

  • Fluids: Water and all liquids

  • Fits a wide range of pipe sizes from 2 inches to 236 inches (50 to 6000 mm)

  • Clamp-on sensors, no pipe cutting, no shutdown

  • Real-time liquid density compensation

  • Optional clamp-on or insertion PT 100 temperature inputs for thermal energy/BTU measurement.
