Smart-Trak 50 Series Medium Flow Controller - .PDF file.

Sierra Instruments has launched the Smart-Trak 50 Series Medium Flow Controller, which increases the maximum flow range of the Smart-Trak 50 Series from 50slpm to 200slpm.

The company developed the instrument for a high-volume OEM customer who had a furnace purge application that required accurate Argon flow control to stabilise gas mass flow and temperature.

The 50 Series builds on the same core sensor, LFE and valve technology found in Sierra’s flagship Smart-Trak 100 Series.

Key benefits

  • Standard accuracy of +/-1.5 per cent of full scale
  • Works for nearly all common semiconductor purge and carrier gases
  • Direct-acting frictionless hovering control valve minimises leak-by, while offering +/-0.25 per cent repeatability
  • Both analogue and digital inputs and outputs are available
  • Can work with older analogue systems or the newest multi-drop digital tools
  • Field adjustment of zero and span enable calibration adjustments to align with on-site process conditions

Sierra Instruments

With in excess of 150 locations in more than 50 countries, our Flow Measurement and Control Division is known for the design and manufacture of innovative high-performance fluid flow measurement and control instrumentation for nearly any gas, liquid and steam application spanning across global industries as diverse as scientific research, semiconductor, wastewater treatment, iron and steel, clean energy, aerospace and biotech, to name a few.

Experience our passion for flow

Our Flow Measurement and Control Division designs and manufactures high-precision capillary-sensor-based mass flowmeters and controllers for gas flow in applications. We also design and manufacture immersible thermal mass, transit-time ultrasonic, vortex shedding and multivariable flow instruments in both standard and customised versions for applications in industrial and hazardous environments.

Our technologies precisely measure and/or control very low flows of gas down to less than 1sccm full scale, as well as extremely high flows of gas, liquid and steam. With rugged product design, cutting-edge innovation and a worldwide team of flow experts, we know you will 'experience our passion for flow'.

Our flowmeters and controllers provide a high return on investment.

  • Direct mass flowmeters provide improved accuracy and cost efficiencies
  • Direct mass flowmeters do not need pressure or temperature compensation equipment or flow computers
  • Flowmeters provide immunity to process changes in P&T, leading to very repeatable measurements
  • In gases, density is highly variable. Unlike mass flowmeters, volumetric gas flowmeters are very sensitive to changes in pressure and temperature
  • Mass flowmeters are a necessity in more than 80 per cent of all industrial processes such as those involving chemical reactions, combustion, respiration and HVAC, which are based on mass flow, not volumetric flow
