The general purpose ultrasonic level sensor provides continuous level detection up to 26.2'(8m) with 3 programmable relays for level switch or level control functions, a 4-20mAoutput 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 II ultrasonic level switch has three SPDT relays each of which can be configured on a single set point to control pumps, valves, or alarms. In addition, all 3 relays can be simplexed, duplexed, or triplexed. The Flowline EchoSwitch II ultrasonic level switch also features an integrated timer with pump / valve delay and timed pump alternation.
The Flowline EchoSwitch II ultrasonic level switch 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 Flowline EchoSwitch II ultrasonic level switch configuration accepts several units of measurement including inches, centimeters, feet, or meters.
