Precision Air Flow Measuring Stations


Controlling airflow rates is essential for the successful operation of today’s high performance buildings.

Outside air for the dilution of contaminants requires precise monitoring and control of outside airflow rates into the building.

Proper pressurization is essential to limit moisture development within the building envelope.

EBTRON has been manufacturing thermal dispersion airflow measurement products since 1984. Our trained application specialists, combined with an extensive local representative network, assure your designs meet the performance requirements demanded for today’s 21st Century buildings.

Ebtron Provides Unsurpassed low flow sensitivity!

  • Each sensor is calibrated at up to 16 airflow rates. All calibration starts from still air. A large signal change with airflow results in accurate airflow measurement, even at low airflows. A microprocessor-based transmitter reads calibration data stored in a memory chip in the sensor probe cable connector plug and “flashes” it into memory during transmitter power up making all EBTRON products “plug and play”.
  • The transmitter essentially reverses the calibration process in the field. Each sensor pair is individually read by the transmitter. The measurements are summed and divided by the number of sensor points. A high speed microprocessor results in virtually instantaneous measurement. As a result, EBTRON technology is ideal for the direct measurement of outside airflow rates and flow tracking applications.
  • In addition, the transmitter is able to detect errors and ignore sensors if a sensor or cable gets damaged. As a result, your system is always running.

Our Gold Series is our “top-of-the-line” airflow measurement solution and is designed around the GTx116 transmitter. The Series is designed for engineers that do not want to compromise system performance. Although our Silver Series has fewer features and a lower sensor density than the Gold Series it is an ideal competitive upgrade to traditional pitot arrays.

-P Duct and Plenum Probes are our most popular devices and should be your first choice when “out of the box” accuracy is paramount.
-F Fan Inlet Sensors are very popular for fan tracking applications when -P probes cannot be used.
-B Bleed Sensors measure airflow and direction through a ˝” tube and are excellent for indirect measurement to flow pressure differentials.

EBTRON also manufactures application specific and custom measuring devices.

All sensors are individually calibrated at multiple points to standards traceable to NIST. Our in-house application specialists work with our local representatives to help you select the best product for your project.
