The Sierra Instruments Flat-Trak™ Model 780S-UHP Ultra High Purity In-Line Mass Flow Meter with Flow Conditioning supports bulk ultra-high purity gas flow measurement in applications where clean gas distribution, gas usage monitoring, and space-conscious installation are important.
It is designed for in-line thermal mass flow measurement and is used in semiconductor fabs, pharmaceutical production, and other ultra-clean process environments.
This flow meter combines 316L electropolished tubing, a 7-10 Ra UHP interior finish, and built-in dual-plate flow conditioning to help reduce upstream straight-run requirements in UHP gas systems.
It is available with buttweld connections and a VCR probe-connection fitting, with transmitter configurations that support flow-range adjustment, validation, diagnostics, and optional local display.
