Liquid Level Inspection Machine

I. Project Overview

Project Title: Liquid Level Inspection System

Project Scope: Designed for real-time detection of product liquid levels with precise online rejection of nonconforming containers.

Maximum Capacity: Up to 72,000 bottles/cans per hour (high-performance model).

Compatible Container Materials: Aluminum, tinplate, PE, PET, PP, ceramics, and glass.

Applicable Product Range: Volume 200–2000 ml; diameter 30–90 mm; height 50–200 mm.

Equipment Model: MT-HFX-06

II. Environmental Conditions

Altitude Requirements: Suitable for operation between 5–3000 meters above sea level.

Ambient Temperature Range: 5°C–40°C.

Relative Humidity Range: 50–65% RH.

Factory Conditions: Floor flatness, load-bearing capacity, and other site parameters must comply with national standards to support stable equipment operation.

Storage Requirements: After delivery, equipment and components must be stored in facilities meeting relevant national standards. Proper lubrication and maintenance should be carried out during storage to prevent surface corrosion or deformation that could hinder installation, commissioning, or normal operation.

III. Production Requirements

Power Supply: 220V, 50Hz, single-phase (customer to provide). For special voltages, prior notice is required; specifications, lead time, and pricing may vary accordingly.

Total Power Consumption: Approx. 1.0 kW.

Control Voltage: 24 VDC.

Compressed Air: 4 Pa–12 Pa (air pipeline from source to equipment provided by customer).

IV. Equipment Introduction

1. Installation Plan

Location: Positioned after the filling machine, either before or after the inkjet printer.

Requirements: Single-row conveyor chain required, with a minimum straight section of 2 meters at the installation site.

Installation Timeframe: Installation to be completed within 24 hours.

Conveyor Modification: A guardrail gap of ≤15 cm in the straight section must be cut to accommodate the reject outlet.

Main Components: Inspection unit, rejection unit, power distribution cabinet, human-machine interface, electronic systems, and mechanical structures.

Rejected Container Collection: Purchaser is advised to construct a rigid collection box at the reject location for defective containers.

2. Inspection Scope

High Liquid Level Detection (auxiliary).

Low Liquid Level Detection (standard).

3. Detection Principle

The system applies X-ray penetration technology. Containers with varying liquid levels create distinct projection patterns at the receiving end, generating different numerical readings. Based on pre-set user parameters, the system evaluates each container’s fill level. If a container is deemed non-compliant, the system automatically triggers rejection.

4. Key Features

Non-contact, in-line inspection with no product damage.

Encoder-based counting method ensures rejection precision is unaffected by line stoppages or speed variations.

Automatically adapts to varying line speeds for dynamic inspection.

Independent inspection and control cabinets minimize electromagnetic interference, ensuring stable performance.

Stainless steel housing and sealed design offer resistance to condensation, water droplets, and harsh environments.

Automatic X-ray shutoff when idle.

Hardware circuit combined with an embedded operating system ensures long-term reliability.

Integrated audible and visual alarms with automatic rejection of defective containers.

5. Technical Specifications

Conveyor Speed: ≤1.6 m/s.

Container Diameter Range: 20 mm–120 mm (final configuration based on container density and size).
