Description
The product is a sensor for level measurement of bulk solids and liquids. The product is suitable to be used in smaller silo applications.
Working principle
The product contains a 77gHz radar sensor to measure the relative distance between sensor and its target.
Installation
General instructions
This product must be mounted on a silo in order to measure the distance to the content surface. Prerequisites (only for NB-loT variants)
The sensor communicates over cellular 4G/5G communication. In order for the sensor to function properly there should be local NB-loT coverage with reasonable quality. Quality is sufficient under the following conditions:
- RSRQ > -lSdBm
- RSRP > -113dBm
- SNR > -3dB
- The following exceptions are allowed (only one exception allowed at a time!):
- RSRQ may be up to -122dBm if no other values are below the thresholds above.
- RSRP may be up to -18dBm if no other values are below the thresholds above.
These conditions can be tested with a network tester.
Tools and equipment
Aerial work platform
An appropriate work platform is required for installation. The roof of the silo has to be reached in a & safe manner in order to install the sensor. Examples of suitable and unsuitable work platform are given below. Always work in a safe environment in accordance with the instructions given for the operation of the equipment
suitable for correct installation
- Able to reach height of silo+ 1 meter
- Open platform
- Support beam mounted to the side of the platform
Example:
not suitable for correct installation
- No open tray
- Support beam mounted at the bottom of the platform
Example:
Safety equipment

Location of the sensor
The location of the sensor must be carefully chosen in order for the product to work properly. The following image represents the silo top view with green coloured locations suitable for installation. The orange coloured sections are not suitable locations for mounting the sensor.
Please follow the numbered mounting recommendations below carefully:
- Preferred mounting area
Mounting area A is the preferred mounting area for the sensor, see Figure 1 for cylindrical silos and Figure 2 for rectangular silos.
If mounting area A is not available then it is also possible to mount in the centre of the silo (area B), but only under the following conditions:- Area B consists of a removable hatch, which can be opened. Or there is a hatch nearby.
- An inspection is performed to verify that there are no obstacles underneath or near Area B.
Area C marked in the figures is only to be used in case of asymmetric silos, and only in case where the bottom exit is underneath area C. Please see paragraph 5.4.1 for additional instructions for mounting on asymmetric silos.
- Offset from silo wall
Optimal placement of the sensor is at a distance of½ the silo radius from the side of the silo in case of cylindrical silos and 1/4th of the silo width in case of rectangular silos, see Figure 1 and Figure 2. The sensor should never be placed closer than 50cm to the side of the silo. - Offset from fill pipes and other (metal) objects.
Fill pipes entering the silo might protrude into the silo and occupy the area marked in Figure 1 and Figure 2. In order to avoid unwanted reflections from pipes, the sensor must be mounted with sufficient distance from this area. Rule of thumb is to keep at least 40cm distance from any visible tubes, hatches - Silo roof angle
The device should preferably be mounted on level surface to avoid the signal deflection. In case the device is mounted on an angled surface the roof angle should be less than 20 degrees. If the rotation of the mounting bracket is not sufficient to get the sensor leveled, the silo is unsuitable for installation with the regular mounting bracket and an angled adapter plate should be used (see installation option in 5.5).
Additional instructions for silos with an asymmetric cone (offset)
In some cases, the cone of a silo has an offset, so the shape is not symmetrical. In this case additional requirements for the positioning of the sensor must be met. 
In case of an asymmetric cone the following two requirements must be met:
- The sensor should be positioned above the bottom exit, preferably at a distance of½ the silo radius from the side of the silo (1/4th the silo width in case of rectangular silos) and also keeping in mind the other general restrictions described in 0.
- The sensor should be located above line A for as much as possible (see Figure 4), while keeping in mind the restrictions regarding potential presence of fill pipes as described in 0. A slight offset from line A is allowed as long a placement is still within the green area in Figure 4.
Selection of installation method
Use the silo application fact sheet to determine the best installation method. This depends on the silo material and thickness, silo geometry and feed type.
- Ml: Non intrusive installation, on GRP silo
Glued on top of silo. No need for modifications of the silo or an opening in the silo wall. The sensor measures through the silo wall. See appendix A for installation instruction of method Ml. - M2. Installing the sensor on top of the silo with a flat or angled plastic screen (adapter).
Pay Attention! Make sure the silo does not contain dust!
Note, this method can cause pollution to the silo during drilling/installation. It is required to clean the silo to remove residues from installation.
M2A: Installation on GRP silo with radar screen or adapter
A hole will be drilled in the top of this silo. The hole will be permanently covered and closed with a screen that enables the radar signal to penetrate through the silo. The sensor is then installed on the screen.
M2B: Installation on metal silo with radar screen
Same as M2, but on metal silo.
See appendix B for installation instruction of method M2. - M3. Using radar screen, “on removable part”.
In this case the same radar screen will be used as mentioned above. However, the screen and sensor will be placed on a removable part of the silo (e.g. hatch) that will be disassembled for installation.
First the removable part (e.g. hatch) will be disassembled and the silo will be covered to protect against ingress. Secondly a hole will be drilled in the disassembled hatch. The hole will be permanently covered and closed with a screen that enables the radar signal to penetrate through the silo. The sensor is then installed on the adapter plate and the hatch is reinstalled on top of the silo.
See appendix B for installation instruction of method M3.
Photographing the device and installation
Take the following photos of the device and installation after the installation is complete:
Take a photo of the device
- Take a photo of the device where the serial number is clearly visible (photo 1 in the installation app).
- Take a photo of the device with a leveler placed on the device, such that the level of the device can be checked (photo 2 in the installation app).
- Take a photo such that the location of the device relative to the silo roof is clearly visible (photo 3 in the installation app).
Taking photographs of the silo - Take a photo where the entire silo is in frame and the silo number (if present) is clearly readable (photo 4 in the installation app).
- Take a photo where the installed silo can be seen with surroundings. Relevant surroundings can be, other installed silo’s or the location on the premises (photo 5 in the installation app).
Measuring the silo
The dimensions of the silo should be filled in on the corresponding measurement form for the correct shape of silo. Instructions for taking the measurements can be found in appendix C, examples of the measurement forms can be found in appendix D Also write down the product UID and silo details on the form.
Register the product and silo dimensions
Submitting with the app
- Go to: https://apps.dutchsense.net/apps/silo/link-devices
- Fill in group name. Example: Abel Sensors Group
- Choose silo and select Install
- Enter UID of the device and select Choose Device
The app performs a check on the state of the sensor. Contact the Abel supportdesk when faults appear. - Confirm that installation is performed according to the installation procedure by selecting Yes.
- Select New installation.
- Read instruction and select Next
- Enter Silo dimensions and select Next
Abel Sensors will supply a silo dimension sheet with each sensor. This sheet can be found in appendix A.l. During installation this sheet should be filled in. The filled in silo dimension sheet should be kept as backup for administration and troubleshooting purposes. - Submit photographs and select Next. Five pictures must be uploaded, the last is optional. This can be used for particularities or uploading a silo type plate.
