Monitor and Sensor Installation 3-3
Installing the Sensors in the Pipe
There are two types of sensor installations:
Standard Installations
Special Installations
Standard Installations involve installing a stainless steel ring to
mount the sensors in round pipes up to 48 inches (122 cm) in
diameter. Special Installations involve installing stainless steel
bands to mount the sensors in round pipes over 48 inches (122 cm)
in diameter or irregular-shaped pipes of any size. This chapter
includes the procedures for performing sensor installations under
either condition and connecting the sensors to the monitor.
Standard Installation
Performing a standard sensor installation involves the following
process:
Gathering the equipment and supplies
Assembling the ring
Mounting the sensors on the ring
Installing the ring in the pipe
Before beginning the installation, conduct a thorough investigation
of hydraulic and other site conditions. The hydraulics of a site
directly affect the monitor's ability to accurately measure flow
depth and velocity. In addition, measure the horizontal and vertical
pipe dimensions carefully. Even slightly inaccurate pipe
dimensions can significantly skew and misrepresent flow data.
