Flow Controller FC3
Continuous, gravimetric dosage of free-flowing bulk solids
- Electrically controlled flat slider with weighing sensor
- Precise regulation of flow capacity in kg/h
- Summation of total amount in kg
- Compact shape with low installation height,
– ideal for assembly below silos - Control of slider position and position presetting possible
The Flow Controller FC3 is particularly suited for:
- Producing grain blends via controlled dosing from multiple silos – ideal for automated recipe management
- Regulated discharge from silos to ensure continuous feeding of downstream processing equipment
- Retrofitting or replacing outdated dosing and weighing systems with minimal installation effort
Further application examples:
- Continuous production of seed mixtures: Seeds are dosed simultaneously from different silos into a common conveyor, such as a chain conveyor, where the streams are combined in the required proportions.
- Dosing plastic granules and recycled granules in a predetermined ratio.
- Production of feed mixtures by dosing raw materials in the required proportions.
Example: Wheat dosing before the first break – FC3 in operation
Note: For proper operation, the Flow Controller FC3 requires a consistent product supply at the inlet.
Functions
The Flow Controller FC3 is enclosed in a robust steel housing.
An electrically driven slide gate opens continuously according to the desired setpoint.
Free-flowing bulk material passes over a weighing sensor that measures the actual flow rate. The device adjusts the opening of the slide gate until the measured and target flow rates are in balance — enabling precise, continuous dosing.
Applied products
The system is compatible with all free-flowing bulk materials, including: grains, pulses, seeds, granules, pellets, fertilizers, sand, substrates, additives, sugar, minerals and various milled or crushed products.
The main advantages of the Flow Controller FC3 at a glance:
- Low installation height = more available silo space
- Easy integration into existing space
- Accurate and continuous flow rate
- Automated control of material flow
- Process visibility and monitoring
