7-2 IETG FlowHawk Manual
Mounting the Monitor on Manhole
Rung
The simplest way to mount a monitor in a manhole is to attach it to
a rung. FlowHawk monitors come with a standard hook for this
purpose.
 Make sure the rungs are capable of holding the weight of the
monitor and cables. The monitor weighs 13.7 kilograms (30.3
lbs) with added weight coming from the cables.
 The hook must be closed to prevent accidental dislodging from
its support rung. The hook has two pieces, a curved portion
that goes over the rung and a straight portion which closes the
hook underneath the rung. The hook must be closed and the
clamping bolt/nut tight enough to ensure that the straight
closure remains in position.
