How do I mount a Consibio Logger with a radar in a sewer for level and flow monitoring?

Required equipment:

  • Consibio Logger in Rugged Case
  • Vegapuls C21 radar sensor
  • Crossbeam (mounting bar)
  • Cable hanger
  • Measuring stick (for manual water level measurement)

Overview

1. Open crossbeam

2. Slide the cable hanger onto the crossbeam

3. Mount Logger

4. Adjust crossbeam

5. Position cable hanger in center

6. Insert sensor cable in cable hanger

7. Lock sensor cable

8. Manual Water Level Measurement 

9. Calibrate Water Level Measurement 



Step-by-step

0. Pre-Deployment Setup

  1. Charge the equipment - Ensure all equipment is fully functional and that the logger batteries are charged to at least 90% before deployment.

  2. Configure the Logger

    1. Log in to Consibio Cloud.

    2. Locate your Project and navigate to the “Devices” tab.

    3. Select the relevant logger device.

    4. Set the Max Offline Time and Max Measurement Interval to 4 minutes and 30 seconds, respectively, to ensure timely and consistent data collection during deployment.

    5. If the logger is currently in a sleep cycle, press the physical wake-up button to force a check-in.

 

1. Open crossbeam

Open up the crossbeam by unscrewing the wingnut:

 

2. Slide the cable hanger onto the crossbeam

 

3. Mount Logger

Slide the Consibio Logger in a rugged case onto the crossbeam:

 

4. Assemble and adjust crossbeam

Adjust the width of the crossbeam to the width of the manhole and fasten the wingnut. The crossbeam should be as wide as possible to ensure that it will not fall off and into the manhole.

 

5. Position cable hanger in center

Align the crossbeam and cable hanger so they are centered over the channel/invert.

         

 

6. Insert sensor cable in cable hanger


Determine the installation height:

  • High Mounting: Install the sensor near the top of the manhole (if depth is <50 ft / 15 m).

    • Allows monitoring of normal level/flow conditions in the invert while also capturing rising water levels during surcharge events — all the way to the top of the manhole.

  • Low Mounting: Install the sensor 3–4 ft (1–1.2 m) above the highest expected daily level.

    • Provides higher accuracy with less risk of signal disturbance.

 

Install the sensor cable in the cable hanger. Use the two sliders to grip the cable and hold it in place:

7. Lock sensor cable

Lock the cable in the cable hanger in place with a cable tie to ensure that it doesn't move:

8. Retrieve installation parameters to display level (and flow)



9. Verify Level and Flow Data

Check the dashboard to confirm that level (and optional flow) readings look correct:




10. Place the Manhole Cover Back in Position & Verify Signal

Put the manhole cover back on.

Wait 4–8 minutes, then verify that the logger successfully completes another check-in under the Devices tab.

(If the logger is not able to transmit through the cover use the external antenna)

 

11. Adjust Transmission and Measurement Intervals

To preserve battery life, update the logger settings:

  • Max Offline Time: Set to a more reasonable value (e.g., 1-12 hours)

  • Measurement Interval: Set based on your monitoring needs (e.g., 5–15 minutes for long-term deployments)


 

12. Installation Complete

Congratulations — your installation is now complete!
Sit back and enjoy the data coming in.
