Setting the Standard in Thermal Dispersion Airflow Technology

At EBTRON, we specialize in thermal dispersion airflow measurement technology and offer customized solutions that cater to the specific requirements of each project. What sets our sensor nodes apart is their exceptional durability. We use a thermoplastic assembly to house our thermistors and waterproof, marine-grade epoxy, which makes them impervious to moisture, direct water contact, and atmospheric acids. We have tested our sensors by immersing them in saltwater baths and exposing them to fuming acid baths, which is far beyond what you would encounter in the field. Moreover, our sensing nodes are calibrated to comply with NIST traceable airflow standards, and each sensor is independently tested and verified to meet these rigorous standards. All of this guarantees that our equipment will perform optimally in the long run and ensure that your building meets the ASHRAE standards and complies with local and national building code requirements.

Pioneering Compliance in Thermal Dispersion Airflow Technology

At EBTRON, precision is our foundation. Our meticulous manufacturing process begins with calibrating each sensor and adhering to the U.S. National Institute of Standards and Technology (NIST). Each Bead-in-Glass thermistor has a rigorous aging process, ensuring stability. Calibrate it to achieve industry-leading temperature measurement accuracy.

Our commitment to excellence continues with assembling two thermistors into a sensor node. Each node undergoes a comprehensive calibration process in our state-of-the-art wind tunnels, meticulously assessed at 16 distinct velocity points. To further validate our precision, we employ an airflow reference standard calibrated within the renowned NIST air speed wind tunnel, cross-verified by a Laser Doppler Anemometer. This standard consistently demonstrates the lowest statistical uncertainty, especially within the required operating velocities, ranging from 10 to 5000 fpm.

At EBTRON, our dedication to quality and accuracy is the cornerstone of our commitment to providing the most reliable airflow measurement solutions.

With EBTRON airflow measurement solutions, you can confidently navigate the ever-evolving landscape of building codes and standards. EBTRON high sensor density airflow measuring devices incorporated at a minimum in outdoor air, supply air, return air, and exhaust air are vital considerations to accurately measure flows to zones in DOAS and VAV systems. Additional airflow measuring devices may be needed to combat wind and stack effects. Avoid CO2 control to provide accurate and repeatable ventilation as it has drift, which is often misunderstood and applied. Select the correct airflow measurement device to suit the application. Whether it is ensuring the minimum ventilation or integrating enhanced ventilation with new control strategies, accurate and repeatable measurement of outdoor ventilation air is necessary to achieve the most efficient system operation and comply with standards and codes. Not only will real-time airflow measurement provide the flow rate, but this valuable data can be used to set upper and lower limits, maintain proper pressurization throughout operating conditions, perform ventilation load calculations, reset rates as conditions change, and initiate alarms.

Ensure you meet ventilation requirements such as the International Mechanical Code (IMC) and Uniform Mechanical Code (UMC) based on the Ventilation Rate Procedure from ASHRAE 62.1. The ventilation healthcare requirements adopted by state health departments and the Centers for Medicare and Medicaid Services (CMS) are focused similarly on ASHRAE Standard 170, which governs pressure flow directions and air change rates for different room types in hospitals and clinics. The International Energy Conservation Code (IECC) and ASHRAE 90.1 instruct on demand control ventilation for high-occupancy areas. The California Energy Commission (CEC) has required ventilation rates and DCV for many systems. ASHRAE 189.1 is the standard for high-performance green buildings and references ASHRAE 62.1 and outdoor air monitoring for VAV systems.

Uncontrolled airflow rates affect occupant health, well-being, and thermal comfort. When you combine occupant benefits with the decrease in engineer and owner risk, the cost of airflow measurement (typically $0.10 to $0.20 per sq. ft. of floor area) pales compared to its benefits. Consider incorporating EBTRON into your existing or next high‐performance building!

EBTRON, A measurable difference!

EBTRON’s airflow measurement stations can provide monitoring and verification that the code ventilation requirements are attained. Demand control ventilation (DCV) is required by the energy code in certain applications.


IAQ liability has become a major consideration for design and operation of buildings. As building have tighter construction and attempt to reduce energy usage a balance is required to provide quantities of conditioned ventilation air to improve indoor air quality. A large U.S. insurer of liability insurance programs for architects, engineers, and environmental consultants’ estimates that 49% of claims in court and 60% of the claims dollars for MEP engineers is related to the HVAC system; often these claims are a result of poor IAQ.

Methods of reducing risk exposure target how a building is set up and operated. Control uncertainties for intake airflow can range in relative terms from 5 to 25% for direct methods, and from 20 to 150% for indirect methods. EBTRON provides the best solution for direct measurement and has third party verification for the individual sensors, complete assembly, and for use internationally.
