INTRODUCTION / TABLE OF CONTENTS
Step One
Series ULS is an innovative level sensor family that replaces float, conductance and pressure sensors that fail
due to contact with dirty, sticking and scaling media in small (< 4’/1.25m) to medium (<18’/5.5m) tall tanks.
Applied in skid, machine, tool and process applications, the general purpose sensors are available with single
and multi‐function capabilities including measurement, switching and control.
Features
Simple configuration with ULSX‐CAL software, no more target calibration
Adjustable Loop Fail‐Safe
Easy to reverse mA output
Increased output filtering
