The Flowline EchoSwitch ultrasonic level switch provides continuous level detection up to 26.2ft(8m) with 3 programmable relays for
level switch or level control functions, and is configured via the integral push button display module. Each relay
can be configured on a single set point (high level alarm or low level alarm) or latched on two set points for automatic fill or
empty in simplex (one pump or valve), duplex (two pumps) or triplex (three pumps) level control modes with selectable time delay and
fail-safe logic. The embedded level controller can lower cost by replacing external control hardware. This non-contact liquid level
sensor is ideally suited for corrosive, sticky or dirty liquids, and is broadly selected for pump lift station, sump and day tank level
applications.
The Flowline EchoSwitch can be configured before installation. The switch features
a non-volatile memory preventing set points from being lost even when the switch is powered down. Configuration
is simple using the three push buttons and built-in LCD display. All that's needed to configure the switch is
tank height, maximum fill height, and the measured distances from the bottom of the tank to each set point. The
EchoSwitch configuration accepts several units of measurement including
inches, centimeters, feet, or meters.
