What is the 3DLevelScanner?

The APM 3DLevelScanner™is the only device presently available that delivers accurate measurement of bulk solids and powders – regardless of the type of material or product characteristics, type and size of storage silo, bin or container, and harshness of the storage environment. It incorporates APM's unique dust-penetrating technology to achieve an unrivalled degree of process measurement and inventory control.

APM Technology


Mapping and Echo Detection

Traditional sensors with single transducer are only capable of measuring a single point on the contents surface.

APM implements a circular array of three transducers for beam forming both at reception and transmission.


APM TechnologyHow does it work

By collecting all echoes bounced from the surface area, the patented algorithm of the 3DLevelScanner™ is able to detect: The distance to the material (time of flight for

each echo) The location of every returning echo at the

surface area (by calculating the arriving angle of the echo using the time difference between the received echo at each antenna).

The echoes are being converted to mapping points and constructs the 3D image of the surface area using APM 3DLevelManager™ software.


APM TechnologyHow does it work - General Concepts

SNR – The Signal to Noise Ratio that determines the ability of the 3DLevelScanner to measure the contents of the vessel.

Volume – The volume [%] of the material in the vessel.

Mass – The volume multiplied by the product’s bulk density.

R distance –“R distance” is the absolute diagonal distance measured from the flange level at the mounting position of the 3DLevelScanner.

Mapping Points – are the X, Y and Z coordinates of every measured echo, the 0,0,0 coordinate is at the top center of the silo. {(X-X0)² +(Y-Y0) ²+(Z-Z0)^2}^½ = R X0,Y0,Z0 are the coordinates of the

3DLelvelScanner’s location. Full & Empty Calibration – Distance to 100% and

0% from the flange level of the 3DLevelScanner.

APM Technology How does it work - General Concepts

APM’s 3DLevelScanner™ use low frequency signal of 2 to 7 KHz. Wide Coverage - the lower the frequency the wider the beam angle

(70 ۫) Dust penetration - low frequency implementation results in good

performance at dusty highly moisturized environments.

Installation Procedure


Pre PO Procedure


Installation Preparation – AAF

AAF – Application Approval Form. Go/No Go – Simplify the approving procedure of

new applications. Provides basic understanding of customer’s

expectations from the 3dlevelscanner. Helps in deciding which product best fit the

application (S/M/MV/MVL). To better understand the application, it is

recommended to request a detailed silo drawing. To view the AAF – click here.


Installation Preparation - IPF

IPF – Installation Preparation Form. To be filled after an order has been made. Main Objective – Maximum information before

shipping & installing the 3DLevelScanner. More information needed:

Detailed drawing of vessel is mandatory at this stage.

Drawing of 3DLevelScaner's Location – to verify that APM’s positioning guidelines are applied

To view the IPF – click here


Installation Preparation

Positioning Guidelines

Always use the 3DLocator Software to finalize position.

1. Not centered

2. Clear vision to material

3. 90° to the ground

4. At least 10 mm (0.4”) gap between the socket’s floor and the antenna's bottom



Positioning Guidelines (cont.)

6. Orientation:i. The mounting direction is indicated by a tendon on the unit.

ii. The 0º should point to the center of the vessel (including square vessels and open bins).
