Method and apparatus for pulsed ultrasonic doppler measurement of wall deposition
First Claim
1. A method for monitoring and measuring the buildup of deposits on the inner surface of a pipeline containing flowing fluid, comprising:
- (a) transmitting a first acoustic signal into the pipeline through the pipeline wall;
(b) receiving echoes of the transmitted signal; and
(c) determining from the received echoes how far from the pipeline inner surface the interface between the deposits and the flowing fluid lies.

Abstract
A method for monitoring and measuring the buildup of deposits on the inner surface of a pipeline containing flowing fluid comprises (a) transmitting a first acoustic signal into the pipeline through the pipeline wall, (b) receiving echoes of the transmitted signal, and (c) determining from the received echoes how far from the pipeline inner surface the interface between the deposits and the flowing fluid lies. An alternative method for monitoring and measuring the buildup of deposits on the inner surface of a pipeline containing flowing fluid comprises (a) transmitting a first acoustic signal into the pipeline through the pipeline wall, (b) receiving echoes of the signal, and (c) using the Doppler frequency shift of the received echoes to determine how far from the pipeline inner surface the interface between the deposits and the flowing fluid lies. An apparatus for monitoring and measuring the buildup of deposits on the inner surface of a pipeline containing flowing fluid, comprises a first transmitter in acoustic communication with the pipeline wall and generating a transmitted signal, a first receiver in acoustic communication with the pipeline wall generating received echo signal from a received signal comprising the reflection of the transmitted signal off the flowing fluid, and a microprocessor for determining from the received echo signal how far from the pipeline inner surface the interface between the deposits and the flowing fluid lies.
