Level Measurement For Plastic Pellets And Powder Handling
Plastic processing plants require reliable level measurement for plastic pellets, powder materials, PET flakes, EPS, compound materials, mixing bins, storage silos and central feeding systems. SHAO provides level measurement solutions for plastic raw material storage, powder handling, granule conveying and automated production lines.
Why Plastic Material Level Measurement Needs The Right Sensor
Plastic processing applications include pellets, powders, flakes, dry blends and compound materials. These materials may flow differently depending on particle size, density, moisture, static electricity and feeding method. A suitable level measurement solution should consider whether the material is powder or granule, whether dust or buildup is present, and whether the production line needs continuous level monitoring or point level alarm.

PET Flakes
Monitoring for PET flakes, recycled plastic flakes and irregular recycled material storage bins.
EPS And Foam Materials
Level detection for EPS, foam plastic raw materials and lightweight granule storage systems.
Compound Materials
Measurement support for compounded plastic materials, mixed granules and blended production materials.
Central Feeding Systems
Level alarm and monitoring for automatic feeding systems, vacuum loaders and material supply lines.
Main Challenges In Plastic Material Level Measurement
Plastic material storage and handling systems often require stable measurement in dusty, lightweight or fast-moving material conditions.
Plastic powders may create dust and buildup inside bins.
Pellets and granules may form uneven surfaces during filling.
PET flakes may be irregular and difficult to measure consistently.
Lightweight materials may be affected by airflow and feeding speed.
Static electricity may influence some sensor applications.
Central feeding systems require reliable alarm and automation signals.
Selection Focus For Plastic Processing Applications
Recommended Solutions By Application

Frequently Asked Questions
What level sensor is suitable for plastic pellet silos?
Radar level meters or solid level switches can be used depending on whether continuous inventory monitoring or point level alarm is required.
Can radar level meters measure plastic powder?
Yes. Radar level meters can be used for many powder storage applications, but dust, buildup, silo size and installation position should be considered.
Which solution is suitable for PET flake storage?
PET flakes may have irregular surfaces and inconsistent flow behavior. Radar level measurement or point level detection can be selected according to the storage bin and control requirement.
Why is level measurement important in central feeding systems?
Reliable level monitoring helps prevent material shortage, feeding interruption, overflow and unstable production in automated plastic processing lines.
What information should I provide before requesting a quotation?
Please provide material type, bin or silo size, measuring range, dust condition, feeding method, installation position, required output signal and site photos if available.
