  • Publication number: 20160231022
    Abstract: This invention relates primarily to an electric heater based tankless water heater, though some aspects may also apply to a natural gas or other fuel based tankless water heater. In particular aspects relating to “smart” communication and coordination of the tankless water heater with other devices, which may be electrically powered or powered by other fuels, may also apply to non-electric flow through fluid heating systems. The subject tankless water heater invention incorporates several aspects relating to energy and construction efficiency which will be detailed further. These include both physical aspects, such as coatings, tubing and heater element design, and electrical aspects, such as power control for individual heater elements, which can make the tankless water heater more compact and more efficient in operation, with reduced instantaneous and long term load on electrical supply systems.

  • Patent number: 9310327
    Abstract: An apparatus and process for making noncontact measurements of liquid conductivity are disclosed. This apparatus forms a conductivity cell and uses two toroids, one to generate a magnetic field and another to sense the magnetic field, placed in an enclosure which allows liquid to pass through it for measurement. Ground planes constructed preferably of printed circuit boards with conductive layers are used to reduce capacitive coupling between the toroids and provide better shielding. Circuitry on or near these circuit boards are used to convert local, low level signals from a sensing toroid to signals which can be more readily passed to and from a recording system or operator without degradation. Sensors on or near these circuit boards can be used to sense environmental conditions in order to improve operation and stability of the conductivity cell. Methods and apparatus for increasing circuit sensitivity and calibrating the sensor are also disclosed.
