<p>"ELECTRONIC LIVESTOCK WATERING DEVICE" Conventional stock watering devices include mechanical water level controls, floats and linkages within an immersion heater and usually bi-metallic strips are used to control temperatures. All of these components are easily corroded particularly when highly mineralized water is often the only source. The present device eliminates all moving parts with the exception of an electronically controlled solenoid valve for opening and closing the water intake line. It is controlled by electronic sensors within an insulated stainless steel tank which includes a heat blanket bonded to the base thereof. Furthermore it includes an automatic shut down capability if there is no water in the tank. All of the controls are contained within an insulated casing which in turn may be maintained at a working temperature by means of a separate heater if desired.</p> |
