- Hammer
- Wrench
- 6x 5/16 in (8 mm) concrete anchor
- 5/16 in (8 mm) eye bolt
- 3/8 in (10mm) concrete rawlplug
- 10x Zip-ties
- Carabiner (optional)
Step-by-step
1. Site Survey
Begin by assessing the type of sewer or structure where you intend to install your product. Visualize the setup, considering both the bracket and the level sensor in their desired positions.
In general, please consider the following:
- Space: Is there enough room for the chosen bracket?
- Mounting Surface: Is there a suitable surface available for mounting the bracket?
- Radar Position: Is the radar positioned effectively to monitor the water? It needs a clear line of sight to the water surface - ensure nothing obstructs it.
- Accessibility: Does the bracket interfere with any sewer maintenance (e.g., suction truck
access)? If possible, choose a position where the equipment is as discreet as possible.
Based on the evaluation of the above, select a bracket below suitable for the sewer / overflow structure you are working with.

Our recommendations and experiences
- Bracket nr. 1 Is the choice if you need to service the radar regularly - the brackets foldable
function makes for easy access to the radar. - Bracket nr. 2 Is often used in situations where the clear line of sight for the radar is narrow. The brackets turnable feature makes it possible for you to position it just in the right position.
- Bracket nr. 3 is suitable in situations where the bracket’s mounting area is far from the radar’s monitoring zone. The extendable function of the bracket makes it possible to extend as much as 11.8 in / 300 mm.
2. Preparing the installation
The bracket comes with a sticker that displays the dimensions for the holes you need to drill.
Place the sticker in your desired mounting position and make sure it is level. Drill the holes as indicated.
- Green: 5/16 in drill (8mm): Holes need to be approximately 2 in / 50mm deep.
- Blue: 3/8 in drill (10mm): Hole needs to be the same depth as the length of the chosen rawlplug.
If you do not have the sticker, you can hold the bracket in the desired position and use a permanent marker with your other hand to mark where the holes should be drilled.
Please ensure that the holes are drilled so the bracket is level. Using a spirit level can be very helpful in the process. We always recommend using the guide sticker if it is possible.
3. Mounting the bracket
Remove the nut and washer from the bolt. Hammer in place four (4) stainless-steel concrete anchors in each of the four (4) holes, marked with green in step 2.
Hammer in place one (1) 3/8 in (10mm) rawlplug in the hole marked with blue in step 2. The rawlplug needs to be flush with the wall when finished.
Now place your bracket over the concrete anchors, put on the washer and tighten the nut using a wrench. The nut needs to be tightened with a force of 15Nm.
The eye bolt can be screwed into place by hand or with a wrench - tighten the wrench around the eye and apply force to the end of the wrench to turn the eye bolt.
When you are done, your setup should look something like this.
4. Mounting the radar and Consibio Logger
Start by mounting the Radar at the end of the bracket. Mount the radar in its position by following these steps:
- Untighten the nut from the radar and move it out of the way by sliding it up along the cable.
- Hold the radar in place with one hand, while you use the other to tighten the nut on the top of the radar. Tighten the nut as much as you can, using your hands. If necessary, a wrench can be used to make sure the nut is tightened properly.
When the radar is firmly in place, you can now attach the Logger and excessive cable to the eyebolt using either zip-ties or carabiner. If zip-ties are used, use the two holes in the handle to secure the Rugged Case (Logger) to the eyebolt.

That's it! You are now ready to measure level and calculate flow in your sewers.
