Operation & Maintenance

OPERATION

The FlowVis® is factory-calibrated to be extremely accurate across its full operating range. Any

perceived ‘inaccuracy’ is related to the viewing angle at which the scale is being read. To avoid

so-called ‘parallax error’, it is important to position your eye so that you are looking squarely at the

tip of the indicator arm. To achieve this, simply move your head so that you just lose sight of the

vertical leading edge of the red arm.

Vertical leading edge

NOTE:

Slowly move your head

in this direction to the point
where the leading edge of the
indicating arm is not visible.
