0. Fluidic module:
To create a liquid time indicator that is compact, and wearable, HYT has developed a
completely new high-tech concept, using two flexible bellows at each end of a capillary
tube. The system is sealed in accordance with the most stringent standards used in
the aerospace industry, with each bellow containing immiscible liquids. The exclusive
patented fluidic module represents this complete system.
1. Meniscus:
The two liquids are separated by their intrinsic repulsive properties. . The meniscus
marks the surface separating the liquids in the tube, indicating the time.
2. Bellows:
The bellows are the two reservoirs located at 6 o’clock. They are made of a highly
resistant, flexible alloy four times finer than a human hair. The movement compresses
the left-hand bellow which is emptied of its colored liquid. The other bellow then fills,
and vice versa, moving the liquid within the capillary, and with it the meniscus which
indicates the time.
3. Capillary:
This tube, made from the best quality glass as used in the medical industry, is circular in
shape and contains two immiscible liquids. A surface treatment is applied to the inside
of the capillary, which enables the two liquids to move smoothly without adhering to the
glass.
4. Rewind:
When the colored liquid gets to 6 o’clock (Zone II), it switches to rewind mode, flowing
back to its original position (Zone I).
