An apparatus and method for transmitting ultrasonic energy. In one embodiment, the apparatus can include a vessel, such as a conduit, having a first end, a second end, and a vessel axis between the first and second ends. An ultrasonic energy emitter can be positioned toward the first end of the vessel to direct ultrasonic energy into the flowable substance during operation. An ultrasonic energy focuser can be positioned toward the first end of the vessel at least proximate to the ultrasonic energy emitter to focus the ultrasonic energy toward the vessel axis as the ultrasonic energy approaches the second end of the vessel. A reflector can be positioned toward the second end of the vessel to reflect the ultrasonic energy back toward the ult1.asonic energy emitter. A signal reverser can redirect at least part of the ultrasonic energy propagating away from the ultrasonic energy emitter.
