Product Description

Product Description

In the complex landscape of industrial processes, accurate flow measurement is the cornerstone of efficient operations, quality control, and cost - effectiveness. The KROHNE 6400C Mass Flowmeter, a part of the renowned OPTIMASS series, has emerged as a leading solution in the field of mass flow measurement. Engineered with cutting - edge technology and a deep understanding of industrial requirements, the 6400C offers a comprehensive set of features that make it suitable for a wide range of applications across diverse industries.

 

Exceptional Accuracy:

The KROHNE 6400C Mass Flowmeter is designed to provide high - accuracy mass flow measurement, with an accuracy of ± 0.05% flat. This level of precision is crucial in applications where even the slightest deviation in measurement can have significant implications for the overall process. In the oil and gas industry, for example, accurate mass flow measurement is essential for custody transfer operations. Precise measurement ensures fair billing between producers, transporters, and consumers, preventing financial losses due to inaccurate volume or mass calculations. A deviation of just a small percentage in mass flow measurement during custody transfer can result in substantial monetary discrepancies over time.

 

Wide Rangeability:

The 6400C offers an impressive rangeability, allowing it to measure flows over a wide spectrum. This is particularly advantageous in industrial processes where flow rates can vary significantly depending on production demands or operating conditions. In a food and beverage factory, for example, the flow rate of ingredients such as milk, sugar syrup, or flavorings may change during different production stages. The 6400C can accurately measure these varying flow rates, from the low - flow rates during the initial mixing stages to the higher flow rates during the filling and packaging processes. This eliminates the need for multiple flow meters with different ranges, simplifying the installation and reducing costs.

Robust Construction for Harsh Environments:

The 6400C features a rugged construction that can withstand the harsh conditions commonly found in industrial environments. It is built to resist vibrations, shocks, and mechanical stress. In industries such as manufacturing, where there may be significant vibrations from machinery, or in mining operations where the equipment is subject to rough handling, the 6400C's robust construction ensures reliable performance.
