Installations
The Street Level Installation System provides a way to install
the probe in a round pipe without entering a manhole. This
system uses multi-section poles and expansion rings that fit 6, 8,
10, 12, and 15 inch round pipes in manholes as deep as 15 feet.
The system includes an instruction manual.
Teledyne Isco's mounting hardware can be installed or adapted
for use in many channels. The paragraphs below list additional
bubble line installation methods.
Teledyne Isco offers the Sensor Mounting Plate for these
channels. The stainless steel plate has tabs to mount up to three
sensors. The bubble line carrier also attaches to the tabs (see
figure in the left margin). It is secured in concrete channels by
driving studs into the channel bottom and bolting the plate to the
studs. In an earthen channel, the plate can be held in place by
driving in stakes.
It is possible to mount the bubble line retainer in a U-channel
with a scissors ring base section. Attach the base section to the
channel wall with studs fired from a power-activated stud gun.
Consult the factory for more information, if you must mount the
bubble line in a U-channel.
If you are not using a primary device, or if your primary device is
not listed in Figure 3-4, please consult with the Teledyne Isco
Customer Service Department for installation recommendations.
