Smart-Trak 50 Series - .PDF file.

Sierra Instruments has announced the release of its Smart-Trak 50 Series flow controller for machine builders, systems integrators and end users.

Sharing the same advanced core sensor technology as the Sierra Smart-Trak 100, the Smart-Trak 50 is now available at almost half the price with off-the-shelf delivery at no extra charge.

The Smart-Trak 50 Series can be calibrated onsite and is claimed to deliver an accuracy of +/-1.5 per cent FS ‘The Smart-Trak 50 is a modular design, so users can add communications, displays or future functionality as required,’ said Matthew J Olin, president of Sierra Instruments.

This performance/price ratio was made possible by reducing the number of mass flow controller parts by almost 50 per cent, automating calibration around slightly reduced accuracy and leveraging research and development costs against already developed sensor, valve and LFE technology.

Sierra has also streamlined delivery by stocking the seven most common flow ranges.

OEMs that purchase in volume can achieve greater price reductions.

The Smart-Trak 50 is claimed to deliver an accuracy of +/-1.5 per cent FS, repeatability of +/- 0.25 per cent FS, 300ms response time and 0-50slpm (nlpm) range in a compact footprint.

It comes with 316L SS wetted materials, field zero and span adjust, plus analogue outputs, RS-232 and RS-485, with optional large local display.

Two DB9 connectors are located on either side of the enclosure for convenient wiring and the unit can be calibrated onsite

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
