The EchoSpan series ultrasonic level transmitter from Flowline provides a loop powered 4-20 mA output that can be used to provide the proportional level of liquid in any tank or vessel. The new EchoSpan series offers several new features including push button configuration, adjustable loop fail-safe, easy to reverse mA output and increased output filtering.
The EchoSpan is a general-purpose ultrasonic level transmitter that provides a loop-powered 4-20 mA output to indicate the proportional level of liquid in any tank or vessel. It features simple push-button configuration and adjustable settings such as Loop Fail-Safe, Hold Last, Empty, Full, and current inversion.
The document details how to configure units (inches, feet, cm, meters), set operational ranges using height and fill-height parameters, and utilize target calibration for empty or full volumes. It also provides wiring diagrams, installation guidelines for metal tanks, and troubleshooting steps.
