Case Studies

U.S. – Emissions Research Facility, Colorado

A university-led emissions research project required precise ambient pressure data for accurate gas flow calculations in simulated stack environments. Emissions and Stack Monitoring Instruments deployed digital barometric sensors with temperature-compensated output, enabling reliable real-time correction and contributing to data accuracy in multiple published studies.

U.S. – HVAC Automation in High-Rise Office Complex, Illinois

To manage pressure-based airflow distribution across 40+ floors, we integrated compact barometric pressure sensors with the client’s smart HVAC system. This allowed the building management system to dynamically adjust ventilation rates, resulting in energy savings of over 18% annually and improved indoor air quality monitoring.

Canada – Weather Station Network, Alberta

A regional environmental agency in Alberta upgraded its weather station network with our ruggedized barometric pressure sensors. These sensors offered better drift resistance and cloud-based data access, improving forecasting accuracy and enabling real-time integration with wildfire risk assessment models.
