摘要：
An apparatus for measuring concentration of a material in a process fluid includes an antenna configured to contact the process fluid and a pulse generator coupled to the antenna to generate a microwave transmit pulse through the antenna. A pulse receiver receives a reflected pulse from the antenna and the concentration of the material is calculated as a function of the reflected pulse.
