In the wood processing and papermaking industries, wood chip silos are an important part of storing raw materials. The accurate measurement of their material levels has a decisive impact on the smoothness and efficiency of the production process. The material level characteristics of wood chip bins are complex and changeable.
They are not only affected by factors such as material accumulation angle, humidity, density, etc., but may also face problems such as bridging and uneven accumulation of wood chips, which all bring challenges to material level measurement.
Against this background, radar level meters have become the preferred solution in the industry with their advantages of high-precision, non-contact measurement.
Let us use a practical case to gain an in-depth understanding of the application of radar level meters in wood chip bin level measurement.
A large paper mill has a wood chip warehouse with a diameter of 20 meters and a height of 15 meters, which is used to temporarily store pre-treated wood chips.
Due to the stacking characteristics of wood chips and the complexity of the warehouse environment, traditional measurement methods such as rope scales or pressure sensors are often difficult to provide accurate material level information, resulting in difficulty in inventory management and potential waste of resources.
To solve this problem, the paper mill introduced an advanced radar level gauge. This device uses microwave pulse technology, which can penetrate dust and steam, and can work stably even in harsh industrial environments.
The measurement principle is to emit microwave pulses and receive echoes, and calculate the material level height through the time difference of the echoes.
The installation location of the radar level gauge is usually chosen in the center of the silo roof to ensure uniform distribution of measurement signals and maximum coverage.
In actual operation, the radar level meter has demonstrated excellent performance. First of all, its measurement accuracy is extremely high, and the error can be controlled within ±1 cm, which is crucial for accurate inventory control and optimization of production plans.
Secondly, because it is a non-contact measurement, it is not affected by changes in the humidity and density of the wood chips, nor is it impossible to measure due to bridges between the wood chips. In addition, radar level gauges are very low maintenance and require little to no regular calibration or other maintenance work.
The application of radar level meter in wood chip bin level measurement not only solves the limitations of traditional methods, but also brings about a double improvement in measurement accuracy and efficiency.
Through the application of this technology, the management of wood chip bins has become more scientific and efficient, bringing positive changes to the entire wood processing and papermaking industry.
Just as art requires precise brushstrokes to depict delicate emotions, industrial production also requires precision tools such as radar level gauges to ensure that every detail is properly grasped and controlled.
