Install the mounting hardware on the wall
Sensor location guidelines
Review the following guidelines to find the best location for the sensor.
Examine the upstream and downstream flow characteristics. Use a mirror if necessary. Install the sensor
above the water where the flow is steady. Do not install the sensor where there are standing waves, pools
or objects or materials that can disrupt the flow profile.
If the upstream flow characteristics are acceptable, install the sensor on the upstream wall of the manhole
with the sensor pointing upstream. This location will make sure that the measured flow is the same as the
flow in the pipe and that the sensor cable points away from the wall.
Install the sensor away from the sides of the pipe and in the very center of the flow where the fluid is at
the maximum depth.
Install the sensor in a location that is accessible for maintenance.
Prerequisites
Permanent or one-time entry mounting hardware
Material needed: Fixings, washers and screws from the correct size
Tools needed: mirror, ruler or tape measure, marker, battery operated power drill, wrench.
Procedure
Complete the steps to install the mounting hardware on the wall of the manhole above the flow. Be sure to follow all
codes and/or directives that are relevant to the location (refer to section 3.2.1 on page - 10 -).
1.
Make a mark on the wall 400 mm above the crown of the pipe. The wall bracket will be installed centered
on this mark.
2.
Make sure that when the sensor is in position, the radar beam will not be blocked by the wall or channel.
Refer to Figure 9 or Figure 11.
3.
Position the wall mount bracket centered around this mark.
4.
Attach the brackets to the wall using anchors and screws.
5.
Connect the rest of the mounting hardware to the wall bracket.
