Product Description

Our solids flow meter MF 3000 is designed for bulk-solids flow measurement in metallic pipes from a few kg/h to many t/h. The system is suitable for on-line measurements of powders, dusts, pellets, and granules from 1nm up to 20mm in pneumatic or free fall conditions. The measurement principle of the MF 3000 is based on the Doppler-Effect, where the sensor generates a uniform field in the microwave frequency range inside the metallic pipe. These microwaves are being reflected by particles passing through the pipe. Calculation of frequency and amplitude changes allows for accurate determination of solids flow. Non-moving particles like accumulated dust are excluded from the calculation.

The installation is simple and cost effective via a welded branch, through which the sensor is screwed flush to the inside of the pipe. The sensor is connected to a DIN-rail mounted transmitter with 4…20 mA, RS232 and RS485 output. The calibration is made easy by using our MF–SMART software and a reference solids flow value.

Material Types:

All dust, powders, granulates, panels, threads etc. Also sticking or abrasive materials.

Range of detection:

From kg/h to many t/h
