ABSTRACT:
Disclosed herein is apparatus for measuring elevation and including an elongated conduit adapted to be filled with liquid and having opposite ends, and a first pressure sensing transducer connected to one end of the conduit for measuring the fluid pressure in that end and including means for producing a first pressure indicative signal. The elevation measuring apparatus further includes a second pressure sensing transducer in fluid communication with the other end of the conduit for measuring the pressure of fluid at that end and including means for producing a second pressure indicative signal, and means for processing the output signals of the pressure sensing transducers, to produce an elevation differential readout.
