Air Velocity Transmitter – Series VTP
The VTP is easily configured or adjusted in the field with the digital display and keypad. The Air Velocity Range and Pressure Range are both field adjustable as well as units of measure. Other adjustable parameters include signal dampening and low velocity cut off point. The VTP Air Velocity Transmitter can also be configured to measure and totalize flow in CFM or M3/h by entering the duct area where the measurement is taken.
Installation of the VTP Air Velocity Transmitter is easy with the adjustable depth, removable flange. The standard product includes an integral design, but is also available with a remote mounted probe to accommodate any application.
