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.
The SolidFlow 2.0-sensor uses the latest microwave technology.
The sensor is used exclusively in metal piping.
The measuring field is generated through the special coupling of the microwave together with the metal pipe.
The microwave coupled into the pipe is reflected by the solid particles and received by the sensor.
The received signals are evaluated with regard to their frequency and amplitude.
The sensor virtually works like a particle counter that counts streaming particles per time unit.
The frequency-selective analysis ensures that only streaming particles are measured.
The SolidFlow 2.0 has a active roping compensation. Based on latest microprocessor-technology, the measuring signal is being dismantled in its frequency spectrum, which enables the sensor to compensate influences of roping.
The calibration of the sensor takes place in the installed state, simply by pushing a button and entering the reference quantity.
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!
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.
