4.4.4 Securing Probe with a
Weighted Plate
In situations with a minimal flow velocity (for example, in a
stilling well), you can simply attach the probe to a weighted plate
and submerge it in the flow.
4.4.5 Completing the Probe
Installation
The submerged probe installation is finished by coiling any
excess sensor cable and securing it using cable clamps or other
means. The reference tube inside the cable can be restricted or
blocked if the cable is kinked, sharply bent, or otherwise pinched.
The probe cable should be handled and mounted with care. Also,
if there is any appreciable distance between the point where the
probe cable leaves the mounting apparatus and the location of
the flow meter, be sure to attach the cable to the flow stream wall
to prevent it from vibrating, moving around, tangling, or possibly
collecting debris.
CAUTION
Do not permit any extra length of probe cable to dangle freely
in the flow stream under any circumstances.
