Description
AV-EP Multi-point Air Velocity Probes available in lengths from 100 to 600mm. They are used to ensure that recommended flow rates for public buildings and industrial plant are achieved and maintained. Using a PA-267, PA-60-x, PA-65-x or PA-699 Air Differential Pressure Sensor of an appropriate range allow the flow rate to be monitored in real-time.
Features
- Push-on connectors to suit 6mm i/d PVC tubing
- Neoprene rubber gaskets duct seals included
- Averages across the duct
- Easy installation
- Fully compatible with PA-267, PA-60-x, PA-65-x or PA-699 DP pressure transmitters
Air Velocity to Differential Pressure

Using the chart to determine the range of the differential pressure sensor:
From the left hand column (velocity, in 1 m/s increments) and the top row (velocity, in 0.1 m/s increments), read across and down to find the corresponding differential pressure.
Examples:
Air velocity is 6.3m/s – Read across from the left to 0.3m/s and down from the top to 6m/s. Where the column and row meet gives a differential pressure of 23.81Pa. Therefore, a differential pressure sensor, with a range of 0 – 25Pa should be selected.
Air velocity is 25.6m/s – Read across from the left to 0.6m/s and down from the top to 25m/s. Where the column and row meet gives a differential pressure of 393.22Pa. Therefore, a differential pressure sensor, with a range of 0 – 400Pa should be selected.
