5 Maintenance

Torbar Averaging Pitot Tube elements have no moving parts,
and do not normally require routine maintenance.

However, depending on process conditions, check Torbar
periodically for signs of blockage, erosion or corrosion. If
withdrawal is necessary, it must be carried out in accordance
with the relevant procedure – see Section 3, page 25.
