The LVU-A700 Series solid state
liquid level switch is a direct
replacement for mechanical
float-type liquid level devices.
The switch employs proven
ultrasonic technology and solid state
integral electronics, and provides
reliable operation in virtually any
liquid, regardless of viscosity. This
eliminates problems of stickiness
and failure rate due to finite
mechanical life inherent in the
mechanical float design. The
combination of fully epoxy-sealed
electronics and ultrasonic sensing
technology will provide years of
maintenance free service.
