LeveleseTM LS-200/CS-100 Dual Overfill Sensor & Control
Introducing the LeveleseTM LS-200/CS-100 Single and Dual Fuel Overfill Level Sensor and Control Station, consisting of of a dual point level sensor with adjustable set points and an electronic Control station with audible and LED visual alarm and shut-off valve control.

The LeveleseTM LS-200/CS-100 has been specifically designed to accurately and repeatably guage diesel engine tanks ranging in depth from 6 inches and switch on (1) a high level alarm and (2) a shutoff alarm and valve shutoff when levels reach near overflow conditions. Features include:

  • Independently-Adjustable Dual Float Operated Level Switches with 2” NPT Mounting and NEMA-4X Enclosure
  • Level Sensor Pressure Sealed to Prevent Leaks
  • Electromechanical Controls with Barrier Strip Termination
  • Surface Mount NEMA-4X Electronics Enclosure
  • Universal 12 or 24 VDC Power
  • Designed to meet the requirements of NFPA-30.


The LS-200 Dual Level Alarm uses two magnetic floats, one for alarm and the other for shut-down, each operating an ndependent, hermetically sealed reed switch activated when the float passes the sensitive portion of the switch. When the fuel level reaches a preset point, the switch changes state. Each switch is rated at 1 Amp, 117 VAC, is mounted on a HDPE tube, passes a leak test of more than 100 psig, is independent from the other and may be field adjusted by moving the HDPE tube and setting it with a set screw.

Designed to meet the requirements of NFPA-30, the LS-200/-CS100 Control Station is a hardened electronic or electromechanical circuit mounted in a NEMA-4X housing. When the alarm level switch is closed, it activates a large Amber LED and Sonalert audible alarm. When the level reaches the Shut-down point, it removes power for the fill pipe solenoid valve, shutting it off and preventing fuel flow into the tank. A toggle switch with OFF, ON and momentary TEST functions is the operator's control over the station.
