Monitor and Sensor Installation 3-21
Performing a special installation involves the following process:
Gathering the equipment and supplies
Mounting the ultrasonic depth sensor
Mounting the Doppler velocity sensor
Mounting the pressure depth sensor
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.
Caution: Handle all sensors and cables with extreme
care. The sensors and cables contain delicate mechanisms
and electronics. Keep sharp objects away from sensor
cables, and avoid stepping or placing heavy objects on the
cable during installation.
Gathering Parts and Supplies
Be sure to obtain the following supplies before performing a
special installation to prevent any costly delays. When ordering,
specify the 4000 flow monitor special installation hardware.
