The LVUC10 liquid level switch is the ideal
solution to a host of liquid level sensing
applications at cryogenic temperatures.
It uses proven ultrasonic technology to
operate in virtually any liquid, regardless
of viscosity or aeration. Its small size and
standard 3⁄4 NPT mounting make it the
perfect choice for new or existing
applications.
The LVUC10 consists of a 316 SS sensor
and an integral miniaturized, encapsulated
electronic control unit which is mounted in
a cast aluminum, explosion-proof,
watertight enclosure. It can be either
integral or remotely mounted.
