Use

MF METER (Solids Flow) uses the principle of the Doppler effect.
A microwave signal is emitted, thereby generating an electromagnetic field inside the pipes. The particles passing in movement in this field generate a signal that varies in amplitude and frequency. The rate of flow is computed from a mathematical analysis combined with a calibration (with real measurements).

The Smart HMI Controller combines the raw signals of all 3 sensors and produces an accurate overall flow measurement usually within +/- 1-3% FS. This intelligent system compensates for material randomly flowing at different concentrations within the pipe diameter.

Why Use Three MF METERs?

Eliminates Flow Profile Bias: Product rarely flows uniformly in wide pipes or chutes. Averaging three independent measurements eliminates errors caused by asymmetrical flow.
Redundant Measurement: Ensures continued operation if one sensor fails.
Improved Accuracy: Captures localized variations, delivering a reliable overall mass flow value.

Function

Beyond the working principle, the technology developed for MultiFLOW METER allows the equipment to compensate for variations in:

Concentration
Speed of particles
Granulometrics
Temperature
Buildup

FOR BETTER PRECISION.
FOR BETTER REPEATABILITY.
FOR BETTER STABILITY OVER TIME.

Contactless measurement
Very easy-to-use device
No maintenance
No remote electronic handling

Mounting and Installation

SENSOR MOUNTING PROCEDURE :

Position the circlip on the waveguide regarding depth of the bushing + valve +
bracket + thickness of the pipe.
For optimal operation, the sensor head should be at least flush with the inside of the
pipe or slightly inside.
Use a depth gauge to determine the exact depth
Unscrew the headless screws of the blue holder bracket.
If you have a valve, open the valve to allow the passage of the waveguide.
Insert the waveguide sensor proper depth.
Secure the sensor with the screws.
