Specifies a method of determining the liquid flow-rate by measuring the mass of liquid delivered into a weighing tank in a known time intervall. Deals in particular with the measuring apparatus, the procedure, the method for calculating the flow-rate and the uncertainties associated with the measurement. Does not cover the cases of corrosive or toxic liquids.
Abstract
Overview
ISO 4185:1980 - Measurement of liquid flow in closed conduits - Weighing method defines a primary laboratory method for measuring liquid flow by collecting and weighing the mass of liquid delivered into a tank during a known time interval. The standard covers apparatus, procedures, calculation of mass and volume flow-rate, and estimation of measurement uncertainty. It excludes corrosive or toxic liquids and situations where vaporization from the weighing tank would affect accuracy.
Key Topics and Requirements
- Principle (static and dynamic weighing)
- Static weighing: tare and gross weighings before and after diverting flow into the weighing tank.
- Dynamic weighing: continuous weighing while flow is delivered to the tank; no diverter required.
- Essential apparatus
- Diverter: fast-acting baffle or nozzle divider (typical travel
