The specified measuring methods are built upon the determination of the volume of liquid collected in a volumetric tank in a known time interval. Deals in particular with the measuring apparatus, the procedure, the method for calculating the flow-rate and the assessment of uncertainties associated with the measurements.
Abstract
Overview
ISO 8316:1987 specifies the volumetric tank method for measuring liquid flow in closed conduits by collecting a known volume over a measured time interval. The standard covers apparatus, procedures, calculation of flow‑rate and the evaluation of measurement uncertainty. Because of its high accuracy, the volumetric method is often used as a primary calibration technique for other flow meters and for legal metrology applications.
Key topics and technical requirements
- Measurement principle
- Two main variants: static gauging (measure level before and after diversion) and dynamic gauging (measure level while filling).
- Apparatus
- Volumetric tank: typically cylindrical, leak‑proof, designed to minimise wall absorption and distortion; large enough to make timing and level errors negligible.
- Diverter: must direct flow to tank or bypass without changing flow-rate; rapid travel recommended (e.g.,
