Flowline LU78 EchoSwitch - Manual (Page 2)

2 of 34 MN300282 Rev A
INTRODUCTION / TABLE OF CONTENTS Step One
The EchoSwitch® is a general‐purpose ultrasonic level switch that provides the end user the ability to control
up to three unique devices (pump, valves and/or alarms) through an advanced non‐contact technology.
EchoSwitch® features push button configuration that uses real engineering values for setting up the relay
operation(s). One relay has SPDT Form “C” contacts useful for controlling a valve and the other two relays are
SPST Form “A”. All of the relays can be used for controlling valves, pumps or alarms.
Features
 Simple digital push button configuration.
 Pump simplex, duplex and triplex option.
 Integrated timer for pump / valve delay and pump alternation.
 Available in a 3m (9.8’), 5.5m (18.0’) or 8m (26.2’) maximum range.
 Isolated 4/20 mA loop output for indicating level.
 AC powered
