1 - Mechanical Installation

General Idea

Placement

When installing the Radar & Tilt Module underneath a plastic lid, consider the following:

• Identify a flat mounting area on the underside of the cover where the back of the device can be fully supported and positioned level. A ribbed surface is acceptable, provided the ribs offer sufficient and even support.

• Ensure there is sufficient space to accommodate two M6 mounting bolts, one on either side of the device. For ribbed covers, the bolts may pass through the ribs, provided they offer adequate structural support.

• Mount the device as close to the centre of the cover as possible, ensuring the radar sensor has an unobstructed view of the liquid surface. Off-centre mounting is acceptable where obstacles prevent central placement.

  • If the device is mounted off-centre, make sure the manhole cover has a keying insert so it can only be installed in one orientation. If there is no keying insert, add a clear alignment mark to ensure the cover is always returned to the same position

Mounting Procedure

1. Hold the device against the underside of the manhole cover and mark the mounting hole positions using one of the following methods:

   • Direct marking: Use a paint marker to mark the two mounting holes from underneath the cover

   • Measurement: Identify the ribs or mounting points where the M6 bolts will pass through, then measure and transfer their positions to the top of the cover

2. Drill two 7mm holes through the cover at the marked positions

3. Secure the device using the following stainless steel A2 components, assembled in order:

   1. Insert two M6 bolts (e.g. Würth Art. No. 0096665), each with an M6 washer (e.g. Würth Art. No. 04096), through the cover from above. Select the appropriate bolt length based on the cover thickness.

   2. Position the device onto the protruding bolts underneath the cover

   3. Fit an M6 washer and M6 nut (e.g. Würth Art. No. 03226) onto each bolt, then tighten to secure the device in place

4. Ensure the device is securely mounted and level when the cover is in its closed position

Required Measurements

Take the following measurements based on whether the manhole or reservoir is cuboid or vertically cylindrical. Also note whether it includes a chimney (narrow access opening) and, if so, whether the device is installed within the chimney, as this affects the required measurements.
