SYSTEM DESCRIPTIONS

GENERAL DESCRIPTION

This Series of Liquid Level Detection systems are ideal, low cost ultrasonic
liquid level detection systems for many applications. They operate in a broad
spectrum of viscous to light liquids.

It uses proven ultrasonic technology with a sensor fabricated completely from

316 Stainless Steel, which allows it to operate in virtually any liquid.
Sensitivity adjustment allows the monitoring of percentage solids in the contents

of the liquid. Its small size standard 3/4” NPT mounting fitting, and ability to be
installed vertically or horizontally makes it the perfect choice for new or existing

applications.
