If you need something special, Sierra customizes often free of charge.ĭIY Calibration: If you prefer to calibrate your own digital flow meters and gas controllers in-house, Sierra provides all necessary software and training and even the flow calibration standards required for the job. Custom valve orifice sizing yields full-range stability. These features assure the best speed and reliability. SmartTrak digital gas mass flow meters have a strong and flexible control valve with accessible PID valve tuning. Quality Calibration: SmartTrak’s NIST traceable accuracy is backed by our 10-point, primary standard calibration over the entire flow range. Q: What Calibration Options are Available for Sierra's Digital Mass Flow Controllers?Ī: Whether you want to take advantage of our industry-leading calibration services or calibrate your meters in-house, Sierra Instruments can support all your calibration needs. Discover The Swiss Army Knife of Mass Flow Controllers The capillary sensor of the digital mass flow controller communicates all the data the control valve needs to actively control the given set point. This signal is directly proportional to the total mass flow through the mass flow controller. The temperature difference is measured by digital electronics and converted to a mass flow signal. 028 inches, which has an upstream and downstream RTD.Īs the gas flows through the capillary sensor, the temperature profile shifts downstream, which is measured by the RTDs. A very small portion of the total flow is diverted through a small “capillary” sensor tube with an ID between. The vast majority of the gas flow passes through the Laminar Flow Element (LFE) bypass. This principle is based on heat transfer and the first law of thermodynamics.ĭuring operation, the process gas enters the inlet of the instrument’s flow body. Digital mass flow controllers for gases operate on the capillary thermal principle of operation. Direct mass flow meters and mass flow controllers count and control every gas molecule flowing through the instruments and are immune to changes in process temperature or pressure. Control is based on direct mass flow, not volumetric flow.ĭirect thermal mass flow controllers offer customers direct mass flow without pressure or temperature equipment or flow computers. Q: How Does a Digital Mass Flow Controller for Gases Work?Ī: A digital mass flow controller automatically controls a specific gas flow rate at a given set point. Lifetime Support: Sierra offers support and calibration services for the lifetime of your product. Localized and Global Support: Sierra’s experienced team operates out of more than 150 locations and can provide sales, installation, calibration, and other services no matter where you’re located.Ĭommissioning: Product specialists are available for installation and any other commissioning services you might need. Multi-gas flexibility: Specify any gas, any flow range up to 1000 slpm (nlpm). Key features of Sierra’s digital mass flow controllers include:Īccurate and repeatable flow measurement: Digital mass flow controllers measure down to the gas molecule, providing accurate and repeatable measurements.Ĭompact footprint: Sierra’s digital mass flow controllers offer the smallest footprint by flow range. This feature allows them to provide the most reliable, repeatable, and accurate gas mass flow for various gases, including natural gas, air, nitrogen, and argon. Sierra Instruments' thermal mass flow controllers are true digital MFCs based on thermal mass flow control technology that directly measures molecular flow by counting gas molecules.ĭigital mass flow meters are unaffected by upstream gas temperature and pressure fluctuations like other differential pressure devices. Over 80% of all industrial processes-such as those involving chemical reactions, combustion, respiration, and HVAC-are based on mass flow, not volumetric flow.
