Using:

SolidFlow 2.0 is a sensor especially developed for measuring the flow rate of solids conveyed in metallic ducts.
It has successfully been tested for online-measuring of:

all types of dust, powder and granulates
grain size between 1 nm and 1 cm

pneumatically conveyed materials or
in free fall after mechanical conveying systems

SolidFlow is wear-resistant and the commissioning is very easy.

For the assembly of the sensor, the installation location is specified in accordance with the conveyed inlet and outlet paths.
In case of pipe diameters over 200 mm, 2 or 3 sensors per measuring point are used, with the sensors arranged at 90° or 120° to each other.
In free-fall applications (e. g. after conveyor screws or rotary conveyors), an inlet path (fall height) of at least 300 mm is ideal. Shorter inlet paths are possible by agreement.
The sensor bracket (welding socket) is welded on at the specified installation location.
After this, a 20 mm-borehole is drilled through the sensor bracket and through the pipe wall. The sensor is then adjusted to the wall thickness, inserted and fixed with the help of the coupling nut. Done!

Commissioning:
The commissioning of the measuring device takes place via the FME analysis electronics. These electronics offer a convenient, menu-driven input of parameters such as measuring range, desired physical units or measuring signal attenuation.
The available outputs are a current output, 4…20 mA as well as a pulse output (open collector).
The menu language options are German, English or French.
