  • Measurement of specific gravity during fermentation
    Patent number: 4959228
    Abstract: A method of determining the specific gravity of a fermentable liquor during fermentation is disclosed. Specific gravity is determined from measurements of original gravity, velocity of sound, and temperature.
    Type: Grant
    Filed: November 13, 1989
    Date of Patent: September 25, 1990
    Assignee: Acumet Precision Instruments Limited
    Inventors: Damir M. J. Skrgatic, James C. Mitchinson, John A. Graham
  • Method and apparatus for ultrasonic measurement of a physical parameter
    Patent number: 4580448
    Abstract: A parameter such as the depth (d) of a liquid (12) in a tank (10) is measured by use of an ultrasonic transducer (14) outside the tank (10). This is possible by choosing the ultrasonic frequency and the thickness of the tank wall such that a defined relationship is satisfied.

  • Method and apparatus for determining physical quantities
    Patent number: 4388708
    Abstract: A distance R to be measured is derived by measuring the spacing x.sub.m between a fixed transmitter Tx and a movable receiver Rx, and comparing this with the reference spacing x.sub.ref between a fixed transmitter Tx' and receiver Rx. Each spacing is measured by passing a large number of pulses sequentially from receiver to transmitter through a coupling medium, the receipt of one pulse triggering transmission of the next. The spacing is derived from the time T taken to pass n pulses; preferably n is fixed and T is measured.
