 Sonar
flow technology provides
a non-intrusive and robust way to accurately and repeatedly measure a wide
range of singlephase and multiphased flows, including pulp slurry, sewage,
and flows with entrained air.
This emerging technology is based on sonar techniques
used for decades in submarine tracking and other underwater acoustic
applications. CIDRA, which introduced proprietary sonar flow technology in
October 2003, developed it for the highly demanding oil and gas production
industry. CIDRA is still the
only manufacturer offering sonar flow processing.
Sonar
flow processing captures two measurements: 1) volumetric flow rate (phase
fraction) monitoring turbulent eddies and 2) compositional (sound speed)
detecting the speed at which sound waves propagate through the fluid
within the pipe.
Unlike
some conventional flowmeter technologies (vortex, orifice plates, flow
nozzles) that create pressure drops by introducing obstructions, sonar
measurement measures naturally occurring turbulence, eliminating pressure
loss and clogging.
