#THERMAL DISPERSIO INSTALL#
Air Monitor’s airflow measurement systems are easier to install and place in real-world applications. Understanding how thermal dispersion airflow measurements work in real-world applications is important.
Our ELECTRA-flo G5 is for stations mounted in ductwork, the ELECTRA-flo/SD is designed specifically for small ducts (16” or smaller), the ELECTRA-flo/FI is designed to be mounted in fan inlets, and the VOLU-trol/E is a combination airflow station and control damper. Our thermal airflow measurement systems are designed to work in a wide variety of applications. Airflow measurement devices are designed for large or small HVAC systems and fan types. We offer a variety of airflow measurement products that use different technologies so that we can meet the challenges of measuring flows in any environment. Our OAM-IIb is specifically designed to work well in outside air applications. In the second, a different technology is the best solution. In the first example above, you can use our built-in three-point field characterization feature to reduce the errors introduced when factory-recommended installation requirements cannot be met. Find Solutions To Airflow Measurement Challenges Another would be measuring outside air at a rain hood, where there is no straight run in a turbulent environment and the instrument is subjected to dirt, dust, rain, fog, sleet, and snow. This technology faces challenges when applied in environments that are outside of these environmental conditions-for example, when there is a limited straight run of duct. Extreme variations of temperature are limited the air is filtered, and the sensors are protected from moisture of any type. There is enough straight run of ductwork upstream and downstream to condition the flow profile. Thermal airflow measurement technology works well in ducted environments because the dimensions and characteristics of common upstream and downstream obstructions are well-defined and understood. The relationship between the mass airflow rate and power needed to maintain the temperature difference is used to calculate the flow rate. As the velocity increases, so does the rate of heat dispersion. One thermistor measures the temperature of the airstream, and the other is heated to maintain a set differential above that temperature. Each point of measurement in an airflow station utilizes two precision-matched thermistors for temperature measurement. A flow stream can transfer and remove heat from a source, cooling it in the same way air takes warmth from you as it flows across your skin. Thermal dispersion airflow stations, also known as thermal airflow stations or calorimetric airflow stations, are used to collect data about flow streams. The Way That Thermal Flow Measurement Works Whether for commissioning, monitoring, or control, airflow measuring stations are necessary for accurate control of ventilation rates, building pressurization, humidity, and energy use. Know About Airflow MeasurementĪirflow measurement devices are a fundamental component of building automation systems (BAS), which are used by controls contractors and mechanical contractors to monitor and control the performance of a facility.
