I. Project Overview
Project Name: Liquid Level Inspection System
Project Scope: This system is designed to perform real-time detection of liquid levels in products and automatically reject containers that do not meet the specified standards.
Maximum Production Capacity: Up to 72,000 bottles/cans per hour (high-performance model).
Applicable Container Types: Suitable for aluminum, tinplate, PE/PET/PP plastics, ceramics, glass, and other common packaging materials.
Product Range: Capacity from 200 ml to 2000 ml; container diameters between 30–90 mm; heights between 50–200 mm.
Equipment Model: MT-HFX-06.
II. Environmental Requirements
Altitude Range: Suitable for operation at 5–3000 meters above sea level.
Ambient Temperature: Optimal range 5°C–40°C.
Ambient Humidity: Recommended relative humidity 50%–65% RH.
Plant Conditions: Floor flatness, load-bearing capacity, and other infrastructure parameters must comply with national standards to ensure normal equipment operation.
Storage Conditions: After delivery, equipment and components should be stored in accordance with relevant national standards. During storage, appropriate lubrication and maintenance are required to prevent surface damage or deformation that could affect installation, commissioning, and long-term operation.
III. Production Requirements
Power Supply: 220V, 50Hz, single-phase (provided by customer). Special voltage requirements must be communicated in advance, as they may impact equipment specifications, delivery schedule, and pricing.
Total Power Consumption: Approx. 1.0 kW.
Control Voltage: 24VDC.
Compressed Air: Pressure range 4–12 Pa. Customer must provide the air pipeline from the main air source to the equipment.
IV. Equipment Overview
1. Installation Plan
Installation Location: Positioned after the filling machine, either before or after the inkjet printer.
Installation Requirements: Must be placed on a single-row conveyor with at least 2 meters of straight-line conveyor length.
Installation Timeline: On-site installation and commissioning can be completed within 24 hours.
Track Modification: A guardrail gap of ≤15 cm should be created on the straight conveyor chain to serve as the reject outlet.
Main Components: Inspection unit, rejection unit, power distribution cabinet, human–machine interface (HMI), electronic control modules, and mechanical assemblies.
Rejected Container Collection: Purchaser is advised to prepare a rigid container at the reject point to collect defective products.
2. Inspection Functions
High liquid level detection (auxiliary function).
Low liquid level detection (standard function).
3. Detection Principle
The system operates on the X-ray penetration principle. Containers with varying liquid levels create different projection patterns on the receiving sensor, which are processed into distinct numerical values. Based on pre-set parameters, the system determines conformity. Nonconforming containers are automatically rejected from the production line.
4. Key Features
Non-contact, in-line inspection with no damage to containers.
Defective container identification via encoder ensures rejection accuracy remains unaffected by line stops or speed variations.
Automatically adapts to varying conveyor speeds for continuous dynamic detection.
Independent inspection and control cabinets minimize electromagnetic interference and enhance operational stability.
Stainless steel housing with sealed structure ensures resistance to fog and water droplets, improving environmental adaptability.
Automatic X-ray shutoff when idle for safety and energy efficiency.
Combination of hardware circuit design and embedded operating system guarantees long-term stable performance.
Integrated audible and visual alarm system with automatic rejection of defective containers.
