Sierra Instruments’ Products Receive Russian Federation Approval For Use In Hazardous Areas

Sierra Instruments, Inc.: MONTEREY, CA – April, 2009 - Sierra’s Steel-Trak™ Model 640S Thermal Mass Flow Meters have recently received both the GOST R Certificate of Conformity (1Exd IIC T6…T2 ) for use in hazardous areas and the Pattern Approval Certificate for Measuring Instruments from the Russian Federation Authorized Bodies.

A GOST R Certificates states that the Steel-Trak™ Model 640S Industrial Thermal Mass Flow Meter is applicable for use in explosive areas.

The Pattern Approval Certificate for measuring instruments (Metrology Certificate) confirms that the particular design of a measuring instrument conforms to applicable standards and that Sierra’s Model 640S has an approved method of factory calibration for use in the Russian Federation.

Both certificates will increase the areas of applications where Sierra’s products can be used in the Russian Federation.

Pattern Approval Certificates for Measuring Instruments (Metrological Certificates) are issued by Rostekhregulirovaniye after comprehensive tests provided by authorized metrology centers.

Mandatory testing of the Model 640S was conducted in the D.I. Mendeleev Federal All-Russian Research and Development Metrology Institute and in the Federal All-Russian R&D Institute for Physics, Technical and Radiometrics Measurements. The extensive testing includes verification of accuracy, repeatability, temperature and pressure limitations, and other flow meter characteristics Approved patterns are then registered in the State Record of Measuring Instruments managed by Rostekhregulirovaniye. The comprehensive tests on the Model 640S also confirmed the safety capabilities of flow meter.

Sierra’s local partner in Russia, APPEC-Service Limited, assumed responsibility for initiating and supporting this project to a successful conclusion. APPEC, based in St. Petersburg, is responsible for all Sierra sales and service in Russia and offers complete technical and application support via a highly trained engineering team.

The addition of GOST and Russian Pattern Approvals to Sierra’s flagship line of industrial thermal mass flow meters allows Sierra to offer an approved product for the global market. Sierra’s industrial thermal mass flow meter line now has CSA and CRN (Canada), FM (USA), ATEX, CE and PED (EU), IEC Ex (Australia), KOSHA (South Korea) and Chinese Pattern Approval (China).

All of Sierra’s industrial thermal mass flow meters are designed for the most demanding industrial gas mass or air flow measurement applications. Featuring direct mass flow measurement, each thermal meter utilizes Sierra’s patented Dry-Sense™ Technology for drift-free performance…year after year. Each model also features Sierra’s Smart Interface™ Package for field programming and meter validation and diagnostics.

Additionally, all of Sierra’s flow meters are calibrated to exacting customer specifications at Sierra’s calibration laboratories and are directly traceable to NIST and compliant to ANSI/NCSL Z540 and MIL-STD-45662A and certified to ISO 9001 standards.
