Mechanical Considerations for Sensor Installation
Install the probe into the pipe through a pre-drilled 1-inch (25-mm) hole in
the pipe using a 1-inch (25-mm) Ball Valve (included). A 1.5-inch or 2-
inch ball valve may be used with reducers.
Installing in plastic or AC (asbestos cement) pipes with smaller diameters
and steel pipes with larger diameters requires different methods.
Plastic or AC Pipes (Fitting Gate Valve)
Plastic or AC pipes require a gate valve; however, no welding is required
to install the gate valve onto a 7.87- to 15.75-inch (200- to 400-mm)
diameter plastic or AC pipe. Simply mount a saddle to the existing pipe,
tighten the lug nuts, and connect the 1.57-inch (40-mm) gate valve. Note
that a 1.57-inch (40-mm) drill bit must be used when boring a hole in the
pipe. Do not install reducers if they will interfere with a protruding drill
bit.
Steel Pipes (Fitting Gate Valve)
To connect a gate valve to a large-diameter steel pipe, first weld a carbon
steel boss directly to the pipe. After welding the boss to the pipe and
pressure-testing the weld, attach a 1.57-inch (40-mm) gate valve.
Note: A carbon steel boss cannot be welded effectively to a
ductile iron pipe. When using the PrimeProbe2 with ductile iron
pipes, use a pipe saddle.
