SolidFlow

Solid Flow Meter for Lean Phase

SolidFlow is a sensor especially developed for measuring the flow rate of solids conveyed in metallic pipes from 20mm to 600mm. The sensor works according to the latest microwave technology. It is wear-resistant and very easy to commission.

This sensor for Solids Flow Measurement has proven track record for online-measuring of:

  • types of dust, types of powder, granulates
  • grain size between 1 nm and 1 cm
  • pneumatically conveyed materials
  • in free fall after mechanical conveying systems

Features

  • Can be used in free fall and in pneumatics
  • Simple retrofitting using a welding socket
  • ATEX-certified
  • Almost all types of dust, powder and granules can be measured
  • No installations in the material stream
  • Online flow metering
  • Throughput measuring up to 20 t/h

The SolidFlow 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 has an 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.
