Acoustically Monitored Separator, a Dual-bore mechanical separator equipped with an ultrasonic transducer for detection
of liquid-liquid/gas-liquid interfaces. The relative proportion of effluent is sensed
by a sound reflection technique that utilizes an acoustic pulse triggered at the
bottom of the measurement bore. The pulse travels upward through the denser fluid
occupying the lower section and is reflected by the fluid interface.
The fluid volume
is determined by the comparison of the travel time of the reflected pulse from the
fluid interface and the simultaneous reflected pulse from a target at a known height
thus performing a continuous calibration allowing the system to determine precise
volumes even in varying density situations such as temperature and pressure variation.
The AMS™-900 can also be used for the measurement of the acoustic velocity of various
fluids such as brines and crude oils at reservoir condition.
The AMS™-900 design allows fluid collection and separation to occur in one bore
while measuring the interface height in a second bore in constant communication,
at top and bottom, with the first. Measurement accuracy is dependent upon the separator
tube being maintained in a true vertical position. System includes a PC based pulsar/receiver
board with oscilloscope capability coupled with a Windows based operating software
allowing ease of use, troubleshooting capability and error checking. When integrated
into a Core Flood system, the board can be connected via a USB port on the control
PC and data integrated with the control program.
