Abstract
In a system and method for sensing and controlling the level of a fluid in a tank, the system includes a fluid inlet, for enabling the flow of fluid into the tank, and a controller, for controlling the flow of fluid through the fluid inlet. The system further includes a sensor, for sensing the level of the fluid in the tank, for activating the controller responsive thereto, and for directing the flow of fluid out of the tank. The system also includes a connector for connecting the sensor to the controller. The sensor comprises a siphon outlet tube, comprised of a conductive material, including a downwardly depending portion which includes a leading edge having a substantial surface area for contact by the fluid upon reaching a preset level in the tank.
Claims22
A system for sensing and controlling the level of a fluid in a tank comprising:
- a fluid inlet, for enabling the flow of fluid into the tank;
- a controller, for controlling the flow of fluid through the fluid inlet;
- a sensor, for sensing the level of the fluid in the tank and activating the controller responsive thereto, and for directing the flow of fluid out of the tank, wherein the sensor includes a leading edge;
- and
- a connector, for connecting the sensor to the controller wherein the controller is adapted to measure the resistance between the level of fluid in the tank and the leading edge of the sensor.
A method of sensing and controlling the level of a fluid in a tank, in a system which comprises a fluid inlet, for enabling the flow of fluid into the tank, a controller, for controlling the flow of fluid through the fluid inlet, a sensor, for sensing the level of the fluid in the tank and activating the controller responsive thereto, and for directing the flow of fluid out of the tank, wherein the sensor includes a leading edge, and a connector, for connecting the sensor to the controller, wherein the controller is adapted to measure the resistance between the level of fluid in the tank and the leading edge of the sensor, wherein the method comprises:
- enabling fluid to flow through the fluid inlet into the tank;
- and
- controlling the flow of fluid into the tank, including sensing the level of fluid in the tank, and activating the controller responsive thereto;
- wherein controlling comprises measuring the resistance between the level of fluid in the tank and the leading edge of the sensor.
