Organization: ASME
Publication Date: 9 October 2006
Status: active
Page Count: 24
scope:

This Standard, provides information on the use of multiport averaging Pitot head-type devices used to measure liquids and gases. The Standard applies when the conduits are full and the flow

(a) has a fully developed profile

(b) remains subsonic throughout the measurement section

(c) is steady or varies only slowly with time

(d) is considered single-phase

A differential pressure transmitter or other pressure measuring device, known as a secondary element, must be used with a multiport averaging Pitot primary element to produce a flow rate measurement.

Although multiport averaging Pitot primary elements are sometimes used in noncircular conduits, such applications are beyond the scope of this Standard.
