Steam Flow Measurement in Semiconductor Fab Facilities – Vortex Flow Meter Applications

In modern semiconductor manufacturing, precision is not limited to microchips—it extends to every utility system that supports the cleanroom environment. One often-overlooked but critical utility is steam, used in multiple processes within wafer fabrication plants.

Accurate steam flow measurement plays a vital role in ensuring energy efficiency, process reliability, and cleanroom stability.

Why Is Steam Used in Semiconductor Fabs?

Semiconductor fabs use steam primarily for:

  • Wet process equipment heating – heating chemical baths in cleaning, etching, and stripping steps

  • Ultrapure water (UPW) generation – heating raw or intermediate water through steam heat exchangers

  • Cleanroom humidity control – using steam-based humidifiers to maintain consistent relative humidity (typically 40–50% RH)

  • Wastewater treatment systems – driving evaporation processes in high-concentration waste treatment

  • Tool sterilization and cleaning – occasional SIP (steam-in-place) systems in critical areas

These applications demand reliable, clean, and precisely controlled steam supply.
