Single Duct terminals are the fundamental building blocks for Variable Air Volume (VAV) systems. Their primary function is to regulate airflow to a zone, in response to zone temperature requirements. ...
inlet condition, an 8 in. VAV box, a flow conditioner, and a straight duct prior to the VAV inlet. A twoaxis airflow sensor (shown in Fig. 5(a)) was modeled for the VAV flow sensor. Only one type of VAV airflow sensor was modeled because the ASHRAE RP1353 project [3,4] revealed that different VAV airflow sensors …
Model: "AeroCross" DESV Flow Sensor. The flow sensor is the most important component of a VAV terminal. The flow sensor measures the total and static pressure in a terminal so that a controller can calculate the cfm through the unit. If the flow sensor does not provide accurate information to the controller, the controller cannot determine ...
The flow sensor is the most important component of a VAV terminal. The flow sensor measures the total and static pressure in a terminal so that a controller can calculate the cfm through the unit. If the flow sensor does not provide accurate information to the controller, the controller cannot determine actual cfm, and therefore cannot maintain ...

CSP5001/5002 VAV Flow ControllerActuators 3 Applications Guide, Rev. B Controller, Sensor, and Thermostat Functions Typical Voltage/Velocity Chart The chart below illustrates typical voltage versus velocity using a CSP with a SSS1002, singlepoint flow sensor. Because this is a flowthrough type sensor,
The Model 36FMS Flow Measuring Station is a multipoint averaging airflow sensor. It has been designed to provide accurate sensing by sampling air velocities in the four quadrants of a round duct. The differential pressure flow sensor …
An airflow sensor in each VAV terminal measures the flow of conditioned air and sends a differential pressure signal to a controller. The accuracy and range of the airflow sensor and controller are critical to the system’s ability to control airflow, outside air dilution and air motion at partload conditions.
