The new microwave technology solids flow meter D3000 is designed for flow measurement in metallic pipes from a few kg/h to many t/h, in pneumatic conveyors and freefalling process applications without any moving parts and mechanical wear.

The measuring principle is based on the Doppler effect with the sensor generating a uniform field in the microwave frequency inside the pipe.These microwaves are being reflected by particles passing through the pipe. Calculation of frequency and amptitude changes allow the accurate determination of solids flow and at the same time exclude non-moving particles such as dust from the calculations.

The solids flow measuring system is suitable for on-line measurements of powders, dust, pellets, and granular products from 1 nm up to 2 cm, in pneumatic or free fall condition.

Installation is simple and cost effective via a welded base, through which the sensor is screwed flush with the inside face of the pipe. The sensor is connected to a DIN-rail mounted transmitter with 4...20 mA, RS232 and RS485 output.
Calibration is easy with software and a reference flow amount.
