Wall Option

1 - Mechanical Installation

The required wall bracket for this installation can be ordered from the IoT Pro Product Selector, under Radar & Tilt Module Accessories > Wall Bracket Selection (update hardware price list)

General Idea

Placement

When installing the Radar & Tilt Module against a wall, take the following into consideration:

  • Install the device on the flattest available section of wall, free from protrusions, steps, pipework, or other structures beneath the sensor that could obstruct or reflect the radar signal

  • Position the device as close to the centre of the reservoir or manhole as practical, while ensuring that it does not obstruct any opening used for filling, emptying, or servicing

  • Where the reservoir or manhole has a narrow access opening or chimney, it is preferable to install the device within this section where possible. This allows the radar to measure the full level range rather than being mounted lower inside the reservoir or manhole.

External Antenna Installation

If the device is supplied with an external SMA antenna connector and a short whip antenna, follow this guide for the correct installation procedure.

Mounting Procedure

  1. Position the wall bracket against the wall at the selected installation point

  2. Using the bracket’s top-right slot as a guide, mark the drilling position and drill the hole using a 6mm masonry drill bit

  3. Insert a suitable 6x40 mm wall anchor (e.g. Würth Article No. 5907206040 or equivalent) through the top-right slot and secure the bracket to the wall. Leave the fixing slightly loose to allow the bracket to be adjusted.

  4. Use the integrated spirit level on the bracket to adjust the bracket until it is level

  5. Mark and drill the top-left fixing hole, then insert and tighten the wall anchor

  6. Repeat the procedure for the two lower fixing slots. Then ensure that all wall anchors are securely fixed.

Uneven or curved walls: Where the wall surface prevents all four fixing points from sitting correctly, use the two centre fixing slots instead

  1. Mount the Radar & Tilt Module onto the adjustable device holder using the supplied nuts and bolts. Ensure that the radar sensor faces outwards, towards the centre of the reservoir or manhole.

Ensure the silver label on the rear of the device aligns with the pocket in the bracket, and that the QR code on the front label faces towards the centre of the manhole

  1. Extend the adjustable device holder outwards to position the device as close to the centre of the reservoir or manhole as practical

  2. Rotate the adjustable device holder until the Radar & Tilt Module is level using the integrated spirit level on the bracket

  3. Tighten the bolt and serrated nut securely to lock the device holder in 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.

Use a weighted sounding tape (or a string with a weight attached) to measure the depth of the manhole or reservoir, and a standard measuring tape to measure the chimney height and other dimensions

  • Length/Height: The actual internal length or height of the tank, excluding any chimney

  • Chimney Height: The vertical distance from the device's sensing surface to the top of the tank. This generally defines the 100% level, but can be increased to set the 100% level lower, providing an additional safety margin.

A minimum chimney height of 5cm is generally configured, even where no physical chimney is present. This provides earlier indication of 100% level and helps prevent the device from becoming submerged when the reservoir or manhole reaches full level.
