Overview

EN 24185:1993 - Measurement of Liquid Flow in Closed Conduits, Weighing Method (ISO 4185:1980) is a European standard developed by CEN. It outlines a standardized weighing method for determining the flow rate of liquids in closed pipe systems. The process involves measuring the mass of a liquid collected in a weighing tank over a defined period, enabling accurate calculation of the flow rate. This method is particularly valued for its reliability and precision in various industrial and laboratory applications. Note that the standard excludes systems handling corrosive or toxic liquids.

Key Topics

Weighing Method: The core procedure captures the mass of liquid delivered into a tank over a known time interval.

Measurement Apparatus: Guidance on the necessary devices, including weighing tanks and timing equipment, ensuring traceable and repeatable results.

Flow-Rate Calculation: Mathematical procedures for converting measured mass and time into standardized flow rate units.

Uncertainty Assessment: Recommendations for identifying and minimizing uncertainties inherent in measurement, ensuring compliance with metrological best practices.

Exclusions: The standard is not applicable to flow measurement for corrosive or toxic liquids due to safety and equipment integrity concerns.

Applications

Implementation of EN 24185:1993 brings significant value to sectors requiring precise liquid flow measurement in closed conduits, including but not limited to:

Industrial Process Control: Monitoring and regulating liquid flows in chemical, water treatment, and food processing plants.

Calibration of Flow Meters: Serving as a reference procedure in calibration laboratories for verifying other liquid flow measurement devices.

Research and Development: Providing an established measurement methodology for scientific experiments involving fluid dynamics in pipes.

Quality Assurance: Supporting compliance and quality management of fluid transfer systems by guaranteeing measurement accuracy and repeatability.

Commissioning of Pipelines: Confirming system performance during the installation or maintenance of pipeline networks.

Related Standards

Several international and European standards align with or complement the guidance provided in EN 24185:1993:

ISO 4185:1980: The international equivalent, forming the basis of the EN 24185 procedure.

EN ISO 4064: Covers water meter specifications and testing methods.

ISO 6817: Relates to testing and verification of flow measurement devices.

EN 1434: Addresses measurements related to heat meters, often involving liquid flow calculations.

ISO 9104: Pertains to methods for determining measurement uncertainty.

Benefits of Adherence

By following EN 24185:1993 for liquid flow measurement in closed conduits, organizations can ensure:

Traceable and standardized results in flow-rate assessments.

Reduced measurement uncertainty, supporting regulatory compliance and process optimization.

Improved safety and reliability in industries where precise fluid management is essential.

This standard is a vital technical reference for ensuring accurate liquid flow measurement, underpinning best practices in industrial, laboratory, and quality assurance environments.
