Apparatus and method for monitoring a sump pump
First Claim
1. An apparatus for monitoring and controlling a motor driven sump pump for a sump having a liquid with a height of an upper surface of the liquid therein, comprising:
- pressure sensing means for detecting a pressure resulting from the height of the upper surface of the liquid within the sump, and including a means for converting the detected resulting pressure into a continuous electrical signal, wherein the continuous electrical signal represents the height of the upper surface of the liquid within the sump; and
,control means comparing the continuous electrical signal to a first preselected electrical signal level that represents at least a first preselected pressure for turning the motor either "on" or "off" when the detected pressure is either above or below the first preselected pressure.

Abstract
An apparatus and method for monitoring and controlling a motor driven sump pump. The apparatus and method includes a power supply which powers the apparatus, a sensing portion which detects the level of the liquid within the sump, a control portion which turns the motor either off or on in response to the level of the liquid, and an alarm portion cooperating with the sensor which activates an alarm when a preselected level has been reached. The apparatus and method also includes power failure detection portion cooperating with the alarm portion which activates an alarm when a power failure occurs, a fault detection portion cooperating with the alarm portion which activates an alarm when the fault condition occurs, and a disabling portion which disables the pump when the fault detection portion detects a fault condition in the pump.
