ABSTRACT:
A high-sensitivity device for measuring the mutual level differentials among a certain number of reading locations, the device comprising a plurality of containers, one for each reading location, mutually connected at the bottom ends by a piping opening into a balancing tank which holds a liquid mass. Each container is equipped in its interior with a float which is held spaced apart from the container walls by flexible retaining members, a level-differential sensitive transducer being mounted in correspondence with the walls. The apparatus further comprises a device for measuring the signals delivered by the transducers.
