ChannelMag
Section 2 Installation
2.4.5 PM2 Sensors in
Non-Full Pipes
The ChannelMag PM Series sensors are used in partially filled pipes from 20” - 120” (500 -
3000
mm) diameter. For pipes 20” - 36” (500 - 915 mm) a single Channe
lMag sensor is installed in a
retention band at the bottom of a horizontal pipe. For larger pipes two sensors are used at the
bottom of the pipe, with their center lines equally dispersed at 15 degrees from the pipe center.
For partially filled pipes a hyd
rostatic level transducer is incorporated in a ramp on the upstream
end of the sensor. The level transducer cable includes a “breather” tube, which is vented in the
remote 4411e transmitter, or in a junction box when the cable is longer than 33 feet (10 m)
. The
cables are run in plastic conduits to the pipe exterior.
