Flow Measurement instrumentation for digital flow meter air measurement solutions

From heavy industrial to research and analytical applications, Sierra has a wide range of digital air flow meters and controllers with digital output protocols. Sierra offers digital gas flow meters and mass flow meters across two core technologies: Capillary Thermal, and Immersible Thermal.

Our electronic digital air flow meters range from our highest performance, industrial, four-sensor QuadraTherm air flow meter, to our more traditional, and also very accurate, two-sensor instruments. Our heavy industrial line is ideal for custody transfer, wastewater treatment, hazardous areas, facilities management and general process control applications where high accuracy is critical. Sierra also offers our flagship line of digital high performance mass flow meters for scientific applications requiring precision measurement.

For increased field flexibility, our electronic air flow meter offers the Dial-A-Gas as a feature to easily change gases, flow rate, modify engineering units or reconfigure the instrument. The QuadraTherm 640i/780i electronic air flow meter also has the capability to change pipe size (Dial-A-Pipe) in the field, adding to the meter's ease of use and flexibility. Connected to the most up-to-date gases in our proprietary Therm Gas Library, this digital air flow meter also updates the instrument via the web. Electronic air flow meter software also features a unique multi-gas flow totalizer.

For easy systems integration with our electronic flow meters, we offer the following digital communications solutions: HART, Modbus RTU,Profibus DP and Foundation Fieldbus.
