Flowline DL14 Series EchoPod® Ultrasonic Level Switch, Controller and Transmitter

EchoPod® Ultrasonic Level Switch, Controller and Transmitter
DL14 Series

The general purpose, ultrasonic sensor provides non-contact level detection up to 49.2” (1.25m) with 4 SPST 60 VA 1A relays and a two-wire 4-20 mA level measurement output. Each relay can be configured on a single set point alarm or latched on two sets for automatic fill or empty in simplex or duplex control modes with fail-safe logic. The embedded controller can replace external control hardware. The sensor is well suited for a wide range of corrosive, sticky or dirty type media. EchoPod is broadly selected for small atmospheric day tank, skid or process vessel, lift station, IBC, drum and sump applications. To configure EchoPod, download our free WebCal software and purchase one USB interface tool.
