 VORTEX FLOW METERS
 
Multivariable Mass & Volumetric Vortex Flow Meters
 
Sierra was the first to introduce a Multivariable Mass Vortex Flow Meter to the market in the late 1990's. Learn more about how this next generation ofMass Vortex Flow Meter technologycame about.  Sierra's Multivariable product line features an inline version, the Model 240 Innova-Mass® vortex flowmeter and a unique immersion version, the Model 241 Innova-Mass®. The Model 241 has emerged recently as the proven instrument of choice ingeothermal steam applicationsacross the globe. The Model 240 and Model 241 can measure the mass flow rate of any gas or liquid and are ideally suited for saturated or superheated steam. The Model 241 vortex flow meter is available in high-pressure versions capable of mass flow measurement of gases up to 5000 psig.
 
Our Multivariable Technology allows one instrument and one process connection to measure FIVE process parameters at the same time to simultaneously measure mass flow rate, temperature, pressure, volumetric flow rate, and fluid density.
 
The Innova-Mass cryogenic version has undergone extensive testing and field validation over the last several years proving that the meter is preferred versus traditional turbine meters for measuring mass flow rates of cryogenic fluids down to -328°F (-200°C).  Using a special cryogenic temperature RTD, mass calculations are done with the latest density equations of state for liquid Oxygen, Nitrogen, Argon, and CO2. All models are fully field-programmable, configurable and feature RS485, MODBUS or HART protocols.   Sierra's Innova-Flo volumetric vortex products, the Model 240V and Model 241V, have the same advantages of the premium Innova-Mass offering, but do not have the temperature and pressure measurement capability.
 
You save money by getting FIVE separate instruments in ONE. Increase your flow knowledge—Try Innova-Mass® when looking for your next vortex shedding flow meter!

 GAS MASS FLOW METERS
 
Scientific Product Family (Gas Mass Flow up to 1000 slpm):
 
Our Scientific Product Family offers you a powerful choice in gas mass flow products.  If you only need to measure the mass flow rate of gas, choose from our line of Mass Flow Meters (MFM).  If you would like to regulate as well as measure gas mass flows, select from among our Mass Flow Controllers (MFC) with integrated valve and control electronics.  Our Scientific Products can be used with any clean dry gas you choose, including mixtures, toxics and corrosives.  The Scientific Product Family utilizes our patented Laminar Flow Element Technology and Thermal Capillary Tube flow sensors to create some of the highest performance, inherently linear mass flow instruments in the world.  Our Scientific Products are widely used for precise measurement and/or control over an enormous flow range:  from ultra low flows (less than 10 sccm) up to 1000 slpm (up to 5600 slpm available upon request).
 
Our Scientific Product family is split into three groups:  Premium Digital, Traditional Analog, and Economical Analog. We also offer Gas Flow Calibrators for validation and primary standard calibration of our Scientific Products.
 
 
Industrial Thermal Product Family (Gas Mass Flow 1000 slpm & higher):
 
Our Industrial Thermal products utilize "Immersible Thermal" sensing technology and are widely used for precise mass flow measurement in light-industry, heavy-industry, hazardous environments, and Ultra High Purity (UHP) applications.  Rugged and reliable, our line of industrial thermal mass flow meters are work horses in industry and are commonly used to measure Air and Natural Gas as well as all other industrial gases and mixtures.  Full scale flow rates are generally above 1000 slpm (35 scfm, lower flows available upon request). We offer a high temperature (HT) industrial thermal version as well for high temperature gas above 375C (700F). Sierra's Multi-Trak™ Model 670S is an advanced state-of-the-art instrument for measuring mass flow rates in very large ducts or stacks that have non-uniform velocity profiles, high turn-down requirements, dirty gas streams, wide temperature ranges and fast velocity and temperature changes.   For high pressure gas above 250 psi up to 5000psi, we recommend our Multiparameter Mass Vortex products as a great optimal solution.
 
Sierra has certified several light and heavy industrial thermal mass flow meters for greenhouse gas (GHG) measurement.  These meters are ideal for GHG measurement meeting all requirements defined by the new EPA rule (CFR 40 Part 98). Our GHG Certified mass flow meters provide an economical way to totalize methane or natural gas burned, enabling the calculation of CO2 equivalent emissions. Sierra has extensive experience in producing highly accurate and repeatable mass flow meters for methane (CH4) as well as N20, SF6, HFC's, PFC's and CO2 as called out in the EPA mandate.

 THERMAL MASS FLOW METERS
 
Thermal Mass Flow Meters for Heavy-Industry
 
North America's #1 selling thermal mass flow meter offering (2009 Flow Research, Yoder), our heavy-industrial thermal mass flow meters are designed for the most demanding industrial gas mass or air flow measurement applications.  These rugged and reliable meters feature the most advanced digital technology and heavy-duty 316 stainless steel wetted materials. All of our thermal instruments feature our proprietaryDry-Sense™ Sensor Technology backed by aLifetime Limited Warranty. Sierra also manufacturers a complete family ofLight-Industrial Thermal Mass Flow Meters.
 
All of our heavy-industrial thermal mass flow meters: Steel-Trak™ Model 640S, Chlorine-Trak™ 760S, Flat-Trak™ Model 780S , and UHP Model 780S feature direct mass flow measurement. Each model also features Sierra's Smart Electronics Package for field-rangeability, flow-range adjustment, and meter validation and diagnostics. Sierra's heavy-industrial thermal mass flow meters have no moving parts and feature digital signal processing, which allow them to work in the toughest environments.  Sierra's Multi-Trak™ Model 670S is an advanced state-of-the-art instrument for measuring mass flow rates in very large ducts or stacks that have non-uniform velocity profiles, high turn-down requirements, dirty gas streams, wide temperature ranges and fast velocity and temperature changes.
