Sierra Mass Flow Meter: SmartTrak Gas Calibration Software
Quick Answer
SmartTrak gas calibration software gives Sierra mass flow meter users the ability to switch between gases on site with no lab recalibration. You select the gas from a library, the meter adjusts its internal curve, and you get a correct mass flow output in a few seconds. This is common in biogas, burner control, and gas blending applications where multiple gases run through the same line. The 4-20 mA signal stays accurate without sending the meter back to a calibration house.
How SmartTrak Calibration Works in Practice
Most thermal mass flow meters ship with one calibration gas. If your process changes from nitrogen to methane, the meter reads wrong. SmartTrak stores up to 10 gas calibrations, each with its own K-factor, density, and viscosity table. The software runs on a Windows laptop and connects via RS-232 or USB to the Sierra meter board. You open the gas select window, click the new gas, and the microprocessor rewrites the flow curve instantly. No screwdriver, no multimeter, no shipping delay.
Here is the thing. Engineers often miss that temperature and pressure compensation stays active during the switch. The software pulls real-time data from the onboard PT100 and pressure sensor if available. So even if your line pressure drifts from 2 bar to 4 bar, the mass flow reading stays within ±1% of rate plus ±0.5% full scale. This matters a lot in LNG sampling and hydrogen blending where small errors cause big safety offsets.
Real Deployment: A Paint Factory in Vietnam
A paint manufacturer in Ho Chi Minh City runs one Sierra 640S on a nitrogen blanket line and occasional solvent vapor recovery. Before SmartTrak, they had to send the meter to a lab for recalibration each time they swapped gases. Calibration took 10 days and cost around USD 400. Last year they bought the SmartTrak kit from Silver Instruments. Now an operator plugs a laptop into the meter during a shift change, selects Acetone Vapor from the list, and resumes measurement in under two minutes. Downtime dropped from 10 days to zero per gas changeover.
Key Specs and Compatible Models
SmartTrak software works with Sierra 600 series, 640, 780, and SmartTrak 100 models. It handles flow ranges from 0-10 sccm up to 0-1000 slpm for gases like air, CO2, methane, propane, argon, and custom mixes. The software also allows user-def
Five Questions Engineers Ask About SmartTrak
Can I calibrate a Sierra mass flow meter for mixed gases? Yes. You can define a custom gas in SmartTrak by entering the exact mole fractions and molecular weight. The software computes the composite K-factor. Lab validation is still recommended for custody transfer, but for process control the calculated curve works fine.
What flow range does SmartTrak software support? From 0-10 sccm up to 1000 slpm, depending on the meter body. Sierra 780 series handles high flows up to 1000 slpm. The software reads the meter tag and adjusts the range automatically.
Is SmartTrak compatible with older Sierra 600 series meters? Yes, all 600 series with digital PCB revision 2.0 or later support SmartTrak. If you have an older analog meter, you will need to upgrade the electronics. Silver Instruments often stocks refurbished 640S units preloaded with 10 gases.
How do I connect a PC to the meter for calibration? You need a USB-to-RS232 converter and the 9-pin D-sub cable that comes with the SmartTrak kit. Plug into the meter top port, launch the software, and select the COM port. The software auto-detects the meter. No special driver required on Windows 10 or 11.
Where can I buy a Sierra meter with SmartTrak calibration preloaded? Silver Automation Instruments supplies Sierra thermal mass flow meters and SmartTrak kits to Southeast Asia, Middle East, Africa, and Australia. They configure gases before shipping so the meter arrives ready to measure your process gas straight out of the box.
