A method for measuring one or more parameters in a fluid in a flow conduit using ultrasound is disclosed, the method comprising transmitting ultrasound signals at a frequency in the range of from about 100 kHz to about 30,000 kHz through the fluid, measuring the amplitude attenuation of the ultrasound signals having passed through the fluid, and using the measured attenuation to measure a parameter in the fluid.
