Note!
• Insertion sensors mounted in DN 80 and 100 (3" and 4") pipes are calibrated in the factory at the actual line
size specified, all insertion sensors for pipe sizes
≥
DN 150 (6") are calibrated on a DN 175 (7") pipe and
numerically scaled to suit the process pipe size (this pipe configuration together with the engineering units
selection is programmable via the integral keyboard and display when fitted).
• Unless stated otherwise, any installation guidance assumes that a standard mounting boss provided by
Hauser is being used.
Vertical alignment
It is important that the sensor mounting boss is welded to the pipe or duct such that the sensor is mounted at
90 degrees to the flow direction. Any deviation from this angle in any plane may cause flow disturbances
around the measuring point that could cause errors.
Flow direction alignment
It is very important that the sensor is aligned correctly with the direction of flow. There are two guidelines for
correct alignment:
• The arrows on the sides of the sensor housing assembly are pointing in the same direction as the flow.
• The graduated scale on the insertion tube section should be aligned directly upstream of the flow direction.
To ensure optimum exposure of the measuring transducers to the flowing gas stream, the sensor must not be
rotated more than 7 degrees from this alignment.
