Accurate and Reliable Flow Meters, Flow Analyzers, and Flow Sensors

All TSI Flow Meters, Certifier™ Flow Analyzers, and Flow Sensors offer the following performance advantages:

  • Fast Response Time: Our instruments provide a rapid four-millisecond (ms) response time, making them perfect for control applications and highly accurate tidal volume measurements.
  • Fully Calibrated: TSI takes pride in calibrating all flowmeters, flow analyzers, and flow sensors against a flow reference and storing gas calibrations on-board. The result is exceptionally accurate measurements.
  • Fully Compensated: Our flowmeters, flow analyzers, and flow sensors are temperature and pressure compensated, ensuring mass flow output remains independent of temperature and pressure fluctuations.
