SYSTEM DESCRIPTIONS

GENERAL DESCRIPTION

The LVUN-600 Series Liquid Level Detection system is an ideal, low cost ultrasonic
liquid level detection system for many applications. It operates in a broad spec­trum of viscous to light liquids.

PRINCIPLES OF OPERATION

PRINCIPLES OF OPERATION

The LVUN-600 Series operates using ultrasonic sound wave propagation. Ultrasonic
sound waves are greatly attenuated when transmitted thr ough air. Conversely,
when liquid is present, transmission of the sound waves is greatly enhanced. The
electronic control unit, either integral or r emote to the sensor, generates electrical
signals that are converted to bursts of ultrasonic energy at the sensor. The ultra­sonic bursts are transmitted across the liquid sensing gap of the sensor. Upon
receipt of a valid signal at the receiver, the solid state electronics generate a “data
enable” condition indicating liquid is present. This signal energizes a relay and
provides an output condition.
