  • assembly 20 is connected to output port via a distal tube 22 and to mouthpiece member 18 via a proximal tube 24.

  • Knowledge of the amount of consumed liquid or, equivalently, the amount of remaining liquid according to some embodiments of the present invention is advantageous for several reasons. First, it is crucial that the body remain properly hydrated, especially during physical activity. Knowing the amount of consumed liquid and/or the rate of liquid consumption aids the user assessing whether he or she maintains adequate hydration.
  • knowing that .the reservoir is running low enables the user to refill or replace the reservoir it in a timely way.
  • the user can also take into account the time period which is expected to elapse before the reservoir is refilled or replaced.
  • the sources of water do not contain safe drinking water, and the water must be filtered or treated with chemicals prior to drinking. Both these activities result in a time period elapsing before the water may be consumed.
  • Reservoir 14 can be either disposable or reusable. When reservoir is reusable, it can include a sealable inlet port 26 which is connectable to a liquid source (not shown) for refilling the reservoir. Inlet port 26 can be sealed by means of a manually operated valve 28 and/or a cap 30. However, it is not necessary for apparatus 10 to include an inlet port even in the case of reusable reservoir.

The rotational motion is transmitted layerwise along the train via the interleaving of the gear disks, up to the upper gear disk 68 which is partially exposed above chamber 65.
  • Scale device 48 typically serves as a totalizer for providing indication as to the amount of liquid passing through assembly 20.

  • the cogwheels transmission system employs 4 transmission layers each of 1:7 reduction ratio. The total reduction ratio is therefore 1:2401.
  • a toroidal turbine ( Figures 2a-c) is advantageous from the standpoint of measurement accuracy. This is because the vanes are confined in a to move within the toroidal channel and the liquid is brought to flow within that channel thus improving the relation between the flow of the liquid and the motion of the vans. In the configuration shown in Figures 3a-c the turbine is placed in relatively large volume and part of the liquid bypasses the vans, making the measurement less accurate.
