ABSTRACT:
A wastewater fluid level sensing and control system is provided. The system comprises a control panel, a reservoir, at least one pump and a fluid level sensing device. The control panel comprises a housing and user interface input and output devices for use with configuring the operation of the control panel. The control panel may be configured to turn on one or more of the pumps to lower the level of fluid in the reservoir. When the level is above a selectable level, the control panel is operative to cause at least one alarm signal to be output. The control panel may include a touch sensor pad mounted to an inner wall of the housing. Changes in capacitance in the pad as a result of a hand being placed adjacent the sensor on the outside of the housing is operative to cause the control panel to silence the alarm.
