CS Instruments VA 400 Flow Sensor For Compressed Air And Gases

Description

The CS Instruments VA 400 Flow Sensor For Compressed Air And Gases distinguishes itself by its ability to be installed under pressure. It is mounted by means of a standard 1/2 inch ball valve, allowing for immediate deployment in active systems. To ensure operator safety during mounting and dismounting, the device features a safety ring that avoids an uncontrolled ejection of the probe which may be caused by the operating pressure.

To accommodate a wide variety of pipe dimensions, the VA 400 is available in multiple probe lengths including 120, 160, 220, 300, and 400 mm. The exact positioning of the sensor in the middle of the pipe is granted by means of the engraved depth scale, ensuring optimal measurement accuracy. The maximum mounting depth corresponds with the respective probe length.
