The Smart-Trak is our flagship mass flow meter and controller. Smart-Trak has demonstrated that premium flow instruments do not have to be hard to use. This combination of convenience with un-matched performance and flexibility has earned the 100 Series awards and praise as one of the finest MFC's in the world. Smart-Trak is the culmination of a massive three year development effort that has created a higher standard of performance for gas flow instruments into the future.

Smart-Trak is designed so the physics are correct! Excellent accuracy and reliability coupled with unsurpassed instrument stability result from a patented, inherently linear design, advanced platinum sensor technology, and a valve that is strong, flexible, and forgiving. Smart-Trak features Dial-A-Gas® Multiple Gas capability so that one single unit may be used with up to 10 gases. The 100 Series is constructed entirely from 316 Stainless Steel, so it can be used with any clean gas including toxics, corrosives, combustibles, and even mixtures of these. The unique Pilot Module replaces expensive control/readout boxes and is available mounted to the face of the instrument or in a convenient hand-held remote version.

• Wide FS flow range for measurement and control of gases from 3 ccm to 2500 lpm, (N2 eq.)
• Accuracy: + 1.0% of rate up to 1100 lpm; 1% FS including linearity above 1100 lpm.
• Industry leading sensor stability. Long term drift performance of < 0.2% per year. Increased system throughput by reducing maintenance and eliminating periodic recipe adjustment.
• Storage of up to 10 selectable calibration curves. Spares inventories are reduced by limiting the number of individual MFC/M's required, lowering inventory holding costs.
• NEMA 4X and IP66 weatherproof protection for 'Hosedown' applications such as: Food, Beverage, Pharmaceutical and Biotech.

The vent-captor type 3202.30 is an air flow meter for industrial applications. The small, self-contained vent-captor is completely epoxy resin encapsulated and operates with high accuracy and repeatability even in harsh industrial environments.The vent-captor can be integrated into measurement and control systems without additional component parts. The newly developed operating principle for the measurement of air flow, based on the calorimetric principle, provides a wide measurement range from 1 to 30 m/s. To achieve the best signal resolution 4 different units are available. The maintenance-free air flow meter is simple to install with the supplied mounting flange. For applications under pressure conditions vent-captor type 3205.30 with stainless steel casing and integral union nut is available.
