Industry-Choice For Bulk High Purity Gas Custody Transfer To Semicon Fabs
FlatTrak™ 780S-UHP
- Optimized for bulk ultra high purity (UHP) gas custody transfer
- Direct mass flow measurement
- No moving parts, 100:1 turndown, low pressure drop
- Reduce straight-run requirements with built-in flow conditioning
- Validate in the field for easy in-situ calibration
Overview
The 780S is North America's #1 selling inline thermal mass flow meter (2009 Flow Research, Boston MA). Our ultra high purity 780S-UHP is the industry-choice for bulk gas distribution service in semiconductor fabs, in pharmaceutical production and other ultra-clean processes. Real-time monitoring of gas usage provides reliable information on consumption and usage patterns in the manufacturing area and may be used for both billing and diagnostic purposes.
The 780S-UHP thermal mass meter is constructed with 316L electropolished tubing with 7-10 Ra (UHP) interior. The 780S-UHP is available in pipe sizes from 0.5 up to 12 inches (1.27 to 30.4 cm) and offered with buttweld connections and a VCR probe-connection fitting.
The 780S-UHP also features Sierra’s unique FlowTrak dual-plate flow conditioning element to eliminate velocity profile distortions as well as swirl and temperature stratification in the gas stream. This product reduces piping straight run requirements to as little as three upstream diameters. As a result, you save money on installation costs when compared to an orifice-plate where at least 20 upstream piping diameters are required for optimal performance.
Operating Principle: Thermal dispersion technology provides direct mass flow measurement featuring: no pressure or temperature compensation needed; no moving parts; low pressure drop; and high turndown. Watch the video.
