Air velocity transmitter is the process of measuring and monitoring the air flow velocities in supply air. These process is useful for ventilators, control flaps and electronic damper registers. We have to place these sensor in air stream path so the person can easily check the status and the amount of air flow. In addition to an on-off signal, it also graphs the analogue values over a moment period. for example, the air flow reduces the web interface will display an indication of change gradually. The measurement range of all type of air velocity transmitter are start from 0 to 1 /1.5 / 2 m/s.

The electronic air velocity and temperature transmitter (AVT) for air and non-combustible fumes with optional relay output. AVT series of air velocity transmitter are developed for building automated system in the HVAC/R sector. These series calculate air velocity and temperature with field selectable array and output options in a single system. These type of transmitter are made with a duct mount sensor and adjustable collar appropriate for round or rectangle-shaped ducts.


AVT includes three field selectable measurement array for air velocity and it can be select by using air velocity jumper. It also includes Separate readings and loop outputs for air velocity and temperature. Some Proportional loop electronic output options include: voltage (0-10V) and current (4-20mA). Air velocity and temperature transmitter with relay output is the main application of these product. These is a best solution to increase your LEED points. One of the LEED objectives is to provide capacity for air flow system monitoring to help promote tenant convenience and well-being. This can be obtained by supplying a direct outdoor ventilation measurement device. These device is capable of calculating the minimal outdoor air consumption flow with an accuracy of plus or minus 15% of the design lowest outdoor air rate.
