VA 400 - Flow sensor for compressed air and gases

The VA 400 for flow measurement of compressed air and gases in a robust housing with and without display with actual flow in m³/h and counter in m³.

Even under pressure, the flow sensor VA 400 is mounted by means of a standard 1/2“ ball valve. During mounting and dismounting the safety ring avoids an uncontrolled ejection of the probe which may be caused by the operating pressure. For the mounting into different pipe diameters VA 400 is available in the following probe lengths: 120, 160, 220, 300, 400 mm. So the flow sensors are being mounted into existing pipelines with inner diameters of 1/2“ upwards. The exact positioning of the sensor in the middle of the pipe is granted by means of the engraved depth scale. The maximum mounting depth corresponds with the resprective probe length. Example: VA 400 with probe length 220 mm has a maximum mounting depth of 220 mm.
