Sierra’s FlatTrak™ 780S for Inline Mass Flow Metering

Date Added: 15th July 2015

Sierra is North America’s number one manufacturer of thermal air flow meters for demanding environments.

They produce a range of inline and insertion meters calibrated for the most demanding high-temperature industrial gas mass and airflow applications. From traditional, accurate, two sensor instruments to the highest performance four-sensor QuadraTherm design Sierra offer the instrument that is perfect for your precision cubic feet per minute (CFM) determinations whatever the industrial setting.

If your installation lacks long straight pipes runs then Sierra’s FlatTrak™ 780S will provide improved measuring capabilities using a traditional thermal two-sensor design. Instalment costs are reduced thanks to its proprietary dual-plate, flow-conditioning element. By eliminating swirl and temperature stratification in the gas stream and velocity profile distortions piping straight run requirements are reduced to as little as three upstream diameters. By comparison optimal performance with an orifice-plate would require at least 20 upstream piping diameters.

The FlatTrak™ 780S has a wide turndown, a very low pressure drop, and is available in pipe sizes from 1/4-inch to 8-inches in a choice of Buttweld, NPT, or ANSI 150 lb flanged design (300 lb flanges are optional). Larger sizes are also available upon request. Meter accuracy is +/ 1% of reading plus +/-0.5% of full scale, with repeatability of +/- 0.2% of full scale.

The FlatTrak™ 780S inline mass flow meter does, of course feature Sierra's well proven Smart Electronics Package (SIP) for field flow-range adjustment, field-rangability and field diagnostics and validation. Tremendous flexibility is offered by the package, enabling full integration and networking capabilities with any industrial application and automated system. Digital communications solutions include: HART, Modbus RTU, Foundation Fieldbus and Profibus DP.

The FlatTrak™ 780S is hazardous area approved by CSA and CRN (Canada), ATEX, CE, FM (USA), and PED (EU), GOST R (Russian Federation), IEC Ex (Australia), and Chinese Pattern Approval (China). It is optimised for highly accurate and repeatable mass flow measurement of gasses, methane (CH4), N20, PFC’s, SF6, HFC’s and CO2.

If you require inline mass flow metering with flow conditioning in demanding environments, where constrained piping means long straight pipe runs do not exist, the FlatTrak™ 780S, with its built-in Dual-Plate flow conditioning element, has to be the meter of choice.
