CS Instruments VA 400 Flow Sensor

CS Instruments VA 400 Flow Sensor 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. CS Instruments VA 400 Flow Sensor for mounting into different pipe diameters VA 400 is available in the following probe lengths: 120, 160, 220, 300, and 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 respective probe length. Example: VA 400 with a probe length of 220 mm has a maximum mounting depth of 220 mm.
