Content available remote A new method of mass measurement for checkweighers
EN
A checkweigher is an automatic machine to measure the weight of in-motion products. It is usually located around the end of the production process and ensures the weight of a product within specified limits. Any products are taken out of line if their weights are out of the specified limits. It is usually equipped with an optical device. It is used to make a trigger to set the time duration to allow a product to move completely on the weigh belt for sampling the weight. In this paper, a new method of mass measurement for checkweighers is proposed which uses just signal processing without the optical device. The effectiveness of the method is shown through experiments. Also a possibility of faster estimation of weight is shown.

In this paper described measurement system model accuracy weighing method of liquid flow in closed conduits, use system structure modeling related by process signals. There is presented model system analyze for pointed high quality of representation properties included in the measurement system model. In this work described way of valuation accuracy measurement system weighing method of liquid flow in closed conduits, using models represented by conceptions of: uncertainty of measurement and error of measurement. Presented measurement system model accuracy to apply an experimental stand for testing and calibration water flowmeter in The Division of Measurement And Control Engineering of Power Plant Processes.
