100 Series Smart Trak

Whatever your criteria, low cost, performance, size, flexibility, or design, Sierra’s new Smart Trak™ digital mass flow controller is hard to beat. Ideal for OEM customers and end-users alike, Smart-Trak offers accurate, reliable performance, an easy-to-use interface, rugged stainless steel construction, and maximum flexibility – at a very competitive price.

	Model 101 Micro-Trak

Sierra Instruments Micro-Trak™ measures and controls micro mass flows of gas previously thought to be too low for a reliable reading. Micro-Trak is specifically designed for flow ranges under 4 sccm with a minimum controllable mass flow rate of 0.1 sccm. The Model 101 Micro-Trak is a specialized and highly engineered instrument for those who need accurate and reliable micro mass flow control of clean gases including corrosives and toxics.

	NEMA 6 Model 180 Max Trak

In applications where frequent wash-down / hose-down is required, such as food and beverage, chemical processing, pharmaceutical and biotech, Max-Trak™ outperforms the competition as it conforms to the rigorous requirements of NEMA 6 and IP67. 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 and forgiving of variations in process conditions.

	240 241 Vortex Innova Mass

Sierra Instruments' Innova-Mass® Multivariable Vortex Mass Flow Meter provides a reading of five process parameters from a single entry point in the pipeline. The meter measures the fluid's velocity, temperature, and pressure and calculates mass flow rate, volumetric flow rate and density. Sensing all process parameters at a single location in one integrated meter greatly improves measurement accuracy and reduces total installed cost.

	Innova Sonic - Portable and Dedicated

The Innova-Sonic™ 210 Portable ultrasonic flowmeter is a state-of-the-art universal transit-time flowmeter incorporating the latest developments in digital signal processing. Sophisticated electronics coupled with powerful ultrasonic transducers deliver highly accurate flow measurement for liquids in full pipes. While principally designed for clean liquid applications, the instrument is tolerant of liquids with a small quantity of air bubbles or suspended solids common in most industrial applications.

	620S Boiler Trak Meter

Sierra Instruments’ Boiler-Trak™ Smart Insertion Mass Flow Meter provides an optimized solution for natural gas flow measurement applications. Boiler-Trak is designed to provide an economical solution to new regulations for the burning of natural gas in heaters and boilers. The meter's sensor offers long-term reliability and a 200 millisecond response to changes in flow rate.

	640S Thermal Gas Mass Flow Meter

The Series 640S allows you to easily configure or change the following password protected parameters: flow range, totalizer, alarm settings, time response, zero flow cut-off and a calibration correction factor that compensates for flow profile variations.

	730 Accu Mass

Sierra Instruments’ Series 730 Accu-Mass™ Flow Meters provide outstanding measurement accuracy and 200 millisecond response time at a reasonable cost. They monitor the mass flow rate of air and process gases (including methane). The Accu-Mass™ meter is available in pipe sizes from 1/4-inch to 1 1/4-inches and delivers an electronic output signal proportional to total gas mass flow rate.

	780S Flat Trak

The 780S Flat-Trak™ flow body eliminates velocity profile distortions, swirl and temperature stratifications in the gas stream and reduces the amount of upstream piping required for accurate flow measurement. The versatile microprocessor-based transmitter integrates the functions of flow measurement, flow-range adjustment, meter validation and diagnostics, in either a probe-mounted or remote housing. Mass flow rate and totalized flow, as well as other configuration variables,are displayed on the meter’s optional 2 x 12 LCD panel.

	810 Mass-Trak

Sierra Instruments' Model 810 Mass-Trak™ offers exceptional mass flow control capabilities at a lower cost than any other thermal mass flow controller. Available in any range from 0 to 10 sccm to 0 to 50 slpm, the Model 810 is suitable for any clean, non-corrosive gas flow control application.

	820S Top Trak

Sierra Instruments' Model 820-S Top-Trak™ is designed for precise measurement of any process gas in ranges from 0 to 10 sccm to 0 to 500 slpm. Because all wetted materials are 316 stainless steel, the device accommodates most clean gases, including corrosives.

	830 840 Side Trak

Sierra Instruments’ Model 830 Side-Trak™ Mass Flow Meters and Model 840 Mass Flow Controllers are designed for precise measurement and control of air and process gases in ranges from 0 to 10 sccm to 0 to 200 scfm. Because all wetted materials are 316 stainless steel, the device accommodates most clean gases, including corrosives.

	Innova Switch

Sierra Instruments’ Innova-Switch represents the State-of-the-art in gaseous and liquid flow switching or liquid level control and continues the Sierra tradition of providing the highest quality mass flow meters and controllers in the industry.

	Cal Trak Gas Flow Calibrators

Sierra Instruments, Inc. presents a new line of portable, low-maintenance, primary standard gas flow calibrators, the Cal-Trak SL-500 and Cal-Trak SL-800. The CalTrak SL-500 offers an excellent accuracy of ±0.35% of reading while the Cal-Trak SL-800 offers the best accuracy of any commercially available standard: ±0.15% of reading! The accuracy of the highest level metrology laboratories worldwide can now be a part of your lab, workshop or production floor when you do-it-yourself with Cal-Trak.
