Description

ABSTRACT:
A means for measuring fluid flow through or into a pipe comprises a fluidistor element (11) arranged in a wall of a pipe splicing piece (10) inserted between sections of the pipe. A pressure sensor (3, 12) senses oscillations in the fluidistor element, and delivers a signal to an analyser (8) for deriving fluid flow rate, density and composition.
