SPECIFICATIONS
A direct replacement for mechanical float type
liquid level devices
Proven ultrasonic technology
Solid state integral electronics
Designed for years of maintenance-free service
The Solid State Float™ LL-10 series liquid level
switch is a direct replacement for mechanical float type
liquid level devices. It employs proven ultrasonic
technology and solid state integral electronics. The Solid
State Float™ provides reliable operation in virtually any
liquid and eliminates failures due to finite mechanical life
inherent in the mechanical float design. With fully epoxy
sealed electronics, combined with ultrasonic sensing
technology, Solid State Float™ is designed for years of
maintenance-free service.
