This Standard specifies the geometric and method of use for orifice meters of 6 mm to 40 mm (1/4 in. to 1 ½ in.) line size when they are inserted in a conduit running full.

This Standard consists of a collection of definitions of those terms that pertain to the measurement of fluid flow in pipes. Only those terms of general usage have been included.

This Standard presents a working outline detailing and illustrating the techniques for estimating measurement uncertainty for fluid flow in closed conduits.

This Standard applies to the steady flow of single-phase gases and deals with devices for which direct calibration experiments have been made.

This Standard describes vortex shedding flowmeters and how the frequency of the vortex pairs is a measure of the fluid velocity.

This Standard applies to axial full-flow turbine meters with mechanical and/or electrical outputs whose rotating member is driven by a compressible fluid and the measurement of gas by a turbine meter.

This Standard establishes methods for determining the influence of installation conditions or flow patterns on the performance of flowmeters in closed conduits (i.e., pipe, ducts, etc).

This Standard describes the practices and means which allow the pressures at a head type primary device to be conveyed to the secondary device in a flow measurement system.

This Standard describes the common variable area flowmeter. This Standard does not attempt to standardize dimensions because the commercial products differ too widely.

This Standard specifies a method of liquid flow rate measurement in closed conduits by measuring the mass of liquid delivered into a weighing tank in a known time interval.

This Standard applies only to ultrasonic flowmeters that base their operation on the measurement of transit times of acoustic signals.

This Standard provides information on the use of multiport averaging Pitot head-type devices used to measure liquids and gases.

This Standard defines the use of tracer (dilution) methods in the measurement of single-phase fluid (gas or liquid) flows in closed conduits.

This Standard describes the criteria for application of turbine flowmeter with a rotating blade for measurement of liquid flows through closed conduit running full.

This Standard applies to AC and pulsed-DC type industrial electromagnetic flowmeters with either wetted or non-wetted electrodes.

This Standard gives guidelines for the selection, installation, calibration, & operation of Coriolis meters for the determination of mass flow, density, volume flow, & other parameters fluids.

This Standard applies to AC and pulsed-DC type industrial electromagnetic flowmeters with either wetted or non-wetted electrodes.

This Standard covers geometry and method of use for pressure differential devices installed in a closed conduit running full and used to determine the flow-rate of the fluid flowing in the conduit.
