Abstract

A method and apparatus for measuring a predetermined parameter, by providing a displaceable sensor (13) on a mounting member (12) such that the displaceable sensor (13) changes in location, form or length with respect to the mounting member (12) in accordance with the predetermined parameter. A cyclically-repeating energy wave is transmitted to or through the displaceable sensor (13), and a predetermined fiducial point in the received cyclically-repeating energy wave is detected and used for continuously changing the frequency of the transmitted cyclically-repeating energy wave such that the number of waves received is a whole integer. The change in frequency is used to produce a measurement of the predetermined parameter. Several embodiments are described wherein the displaceable sensor is a deformable membrane (13), an end wall of a bellows (23), a spring-mounted member (33, 43) a displaceable plunger (53), and a bar changing (163) its length in accordance with the parameter to be measured.
