  • Well cellar high fluid level alarm
    Patent number: 9085961
    Abstract: A well cellar high fluid level alarm includes a control box providing a water-tight enclosure and a alarm control circuitry disposed within the control box. An audible alarm indicator is operably connected to the alarm control circuitry. A visual alarm indicator is operably connected to the alarm control circuitry. A float switch is operably connected to the alarm control circuitry. An electrical power cable is operably connected to the control circuitry and provides electrical power thereto. A control switch is operably connected to the control circuitry and is operable to turn the control circuitry on and off. Operational indicator lamps are operably connected the control circuitry and operates to indicate an on or off state of the control circuitry. The control circuitry operates to operate the audible alarm indicator and the visual alarm indicator upon the float switch sensing a high fluid level.
