A measurement system for remotely measuring a parameter and relative distance having a parameter sensor providing signals to control the pulse repetition rate of a pulse generator, the pulses from the pulse generator in turn controlling a switch to alternately connect and disconnect an energy storage device to the input of a sonic waveguide device. The output signals at the outputs of the sonic waveguide device control a driving device which provides a representation of these output signals on a transmission line arrangement.
