Sierra Expands Award-Winning Flow Meter Lineup

MONTEREY, CA - Sierra Instruments has just announced that they will be introducing their new SmartTrak® 100 High Pressure mass flow meter at the Pittcon Expo, on March 12 in Orlando at booth #2327. The 100 High Pressure is the latest addition to Sierra's award-winning SmartTrak 100 and 50 Series of mass flow meters and controllers.

"We've got the widest variety of options in the industry," says Matthew Olin, President. "If we don't have the ideal digital mass flow meter or controller for your application, it doesn't exist."

"The result of over a decade of user feedback on earlier versions, our 100 Series mass flow meters and controllers deliver the kind of intelligent control, independence and flexibility that leading companies and growth enterprises will need to take advantage of the huge opportunities we see on the horizon," says Olin. "And our 50 Series is ideal for OEMs. They share the same advanced core sensor technology as the 100 Series, but they are now available at nearly half the price."

Reliable, stable and smooth gas mass flow control is now within reach as a result of the proprietary Sierra Frictionless-Hovering Valve Technology(TM) inside every Smart-Trak® 100 and 50. Users can experience the most advanced direct-acting control valve available, and unlike other valves, it has shut-off capability.

With Sierra's Smart-Trak® 100 series, you can independently adjust calibration in the field for any of the 10 pre-programmed Dial-A-Gas® gasses. The user-friendly Pilot Module control/readout interface lets you view and adjust critical control functions at any time.

The performance/price advantage of the Sierra 50 Series was made possible by reducing the number of mass flow controller parts by almost 50% and automating calibration around slightly reduced accuracy. Their modular design means you can add communications, displays or future functionality as you need it. Sierra has also been able to streamline delivery by stocking the seven most common flow ranges. OEM's that buy in volume will see deeper price reductions.

All Sierra SmartTrak 50's and 100's are available for purchase online at

Attendees at Pittcon can purchase flowmeters at Sierra's booth #2327 and get next day delivery for in stock products.
