Our mass flow sensor VA 400 comes in a robust housing in a version with or without an additional display to show the actual flow in m³/h as well as a counter in m³. Even under pressure, the mass 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.
