Select from 10 pre-programmed gases!
Sierra’s Mass-Trak meters measure and control the flow of any clean gas, including toxic or corrosive gases, in any range from 0 – 4 standard cubic centimeter per minute to 0 – 1 000 standard litres per minute. The all-digital Smart-Trak Sierra is pre-programmed for ten commonly used gases! Simply select air, argon, carbon dioxide, carbon monoxide, methane, helium, hydrogen, oxygen, nitrogen or nitrous oxide. The stainless steel construction is suitable for any clean gas and its small footprint facilitates drop-in replacement of any mass flow controller .
With an accuracy of +1% full scale and repeatability of +0.2%, the Sierra Smart-Trak offers versatility and reliability for optimum flow measurement and control.
Gas Mass Flow Meter / Controller
Sierra’s QuadraTherm – the most accurate thermal mass flow meter in the world – measures gas mass flow to unsurpassed accuracy and long-term stability. Using three precision temperature sensors and one patented mass velocity sensor, it measures the mass flow directly of inert gases, flammable gases and corrosive gases. It is inherently superior to meters which measure volume and correct for temperature and pressure. The meter can be simply switched between air, argon, carbon dioxide, chlorine, digester gas, helium, hydrogen, methane, nitrogen, oxygen and propane. It can be calibrated for any other gas or mixture at Sierra’s in-house, independently certified flow laboratory. The built-in facility to perform field validation of the flow calibration meets your quality plan requirements. Available in both insertion and full bore configurations, the QuadraTherm has outputs for mass flow, temperature and pressure.
