Incoming goods inspection

Control and product recognition

LiquiSonic® sound velocity measurements during incoming goods inspection

 

Application

When goods are received, the delivered goods are handed over and then pumped into the respective tanks to check the quality of the goods.

Deliveries are usually made using intermediate bulk containers (IBCs) or directly from tankers. On the one hand, it is important that there is no mixing of different, possibly highly reactive substances and, on the other hand, it is necessary to check the correct concentration of the starting materials within narrow tolerance limits. The liquid concentration is measured directly in an adapter piece at the product inlet before the liquids enter the respective pipeline.

The LiquiSonic® immersion sensor can not only measure the concentration, but also control the product valves via digital output or BUS interfaces to the control system.

 

Advantages of sonic velocity measurement for incoming goods inspection

The LiquiSonic® measuring method, which is based on high-precision sonic velocity measurement, offers significant advantages over conventional methods in the context of incoming goods inspection. Many traditional inspection methods require sampling and subsequent laboratory tests, which are not only time-consuming but can also be prone to errors.

The LiquiSonic® system, on the other hand, enables continuous and non-contact inspection directly in the flow of goods, which means that every delivery can be monitored in real time and without interrupting the process. For companies, this means significantly faster goods receipt, reduced waiting times and greater certainty regarding the quality of the products delivered.

Compared to other methods, LiquiSonic® enables more accurate, efficient and cost-effective inspection, making it a preferred choice for many companies looking to optimize their incoming goods inspection.

 

Installation

LiquiSonic® immersion sensors can be installed directly in the delivery pipeline. The installation location must be selected so that the sensor is fully in contact with the process liquid. It is therefore advisable to install the sensor in rising pipes or alternatively from below in partially filled pipes. The compact sensor design ensures long process service life of the system.

The LiquiSonic® Controller 30 can be connected to up to 4 sensors. This makes it possible to monitor several measuring points at the same time.

Alternatively, with the help of the LiquiSonic® Lab system, spot measurements of samples in the laboratory can be carried out in seconds.

Possible measuring range (depending on the respective liquid):
Concentration range: 0 to 100 m%
Temperature range: -20 to 140 °C

 

Customer benefits

The LiquiSonic® inline measuring system enables precise product detection and analysis of the input concentration of liquid media using the speed of sound. This ensures stable product quality and increases plant safety. There is no need for time-consuming sampling and analysis in the laboratory.

The robust sensor design with no moving parts and no seals guarantees reliable inlet analysis and monitoring in the long term. If required, the sensor parts in contact with the media can be manufactured from special materials such as Hastelloy C2000.

Further advantages for the user are

  • Incoming goods inspection in seconds

  • Monitoring the product quality of the delivery

  • Also for potentially explosive areas

  • No contamination of tanks due to incorrect filling

  • Increased system safety

  • Avoidance of system corrosion

  • error potential

Incoming goods inspection explained

Incoming goods inspection (also known as incoming goods inspection) is a central component in the logistics and production chain and refers to the process in which goods are checked for quality and quantity upon delivery to a plant or warehouse. The main focus is on ensuring that the delivered goods meet the defined requirements and specifications.

The receipt of goods is the first step in the inspection process. Once the goods have been delivered, they are subjected to a thorough quality check in the incoming goods inspection. This inspection can be both visual and technical and serves to ensure quality.

Aspects such as quantity, condition and any damage are examined. After a successful inspection, the goods can be released for storage or further processing. In some cases, if the goods do not meet the specified standards, the goods are removed from stock or returned to the supplier. Incoming goods inspection therefore plays a crucial role in ensuring product quality and contributes significantly to successful operations.

What does an incoming goods inspection involve?

An incoming goods inspection typically consists of several components, all of which are necessary to check the quality of incoming goods as part of good quality management. The incoming goods inspection ranges from an inspection of the delivery documents to a detailed analysis of the components of each individual delivery.

How does an incoming goods inspection work?

Typical process of an incoming goods inspection: During incoming goods inspections in a company, the quantity and quality of delivered goods are checked. After delivery, the goods are first physically recorded and compared with the delivery note data. Random samples are then often taken and tested in a laboratory or test room for their condition and quality.

These tests can vary depending on the goods and requirements, from simple visual inspections to complex chemical analyses. After successful testing, the goods are transferred to the warehouse or integrated directly into the production process. In the event of deviations or quality defects, the goods are rejected or corrective measures are initiated.

Process with integration of the LiquiSonic® measuring system: The integration of the LiquiSonic® measuring system into the incoming goods inspection process significantly optimizes this process. Instead of waiting for time-consuming random samples and laboratory tests, the system enables a direct and continuous check in the flow of goods. As soon as a delivery arrives, the quality of the liquid products can be measured in real time based on high-precision sonic velocity measurement.

This not only significantly reduces waiting times, but also increases the accuracy of the inspection, as the entire product volume is analyzed and not just random samples. Companies benefit from faster goods receipt, improved quality assurance and ultimately a more efficient overall goods flow chain.
