Use

SF 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 in frequency.

Dynamic flow:
The rate of flow is deduced from a mathematical analysis
combined with a calibration (with real measures).

Flow no Flow:
The threshold can be defined between 0 and 100% of flow
A “switch” is activated when the sensor detects a superior or
inferior fixed threshold.

Function

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

Concentration
Speed of particles
Granulometrics
Temperature

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 :

1. 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

2. Unscrew the headless screws of the blue holder bracket.

3. If you have a valve, open the valve to allow the passage of the waveguide.

4. Insert the waveguide sensor proper depth.

5. Secure the sensor with the screws.
