Introduction: The EchoSpan is a general-purpose ultrasonic level transmitter that provides a loop powered 4-20 mA output. The 4-20 mA output can be used to provide the proportional level of liquid in any tank or vessel. The signal can be connected to any device that accepts a loop powered 4-20 mA signal, such as a PLC, SCADA, DCS, display, controller, etc. -

User’s Responsibility for Safety: FLOWLINE manufactures a broad range of level sensing technologies. While each of these sensors is designed to operate in a wide variety of applications, it is the user’s responsibility to select a sensor model that is appropriate for the application, install it properly, perform tests of the installed system, and maintain all components. - Page 6 Make a Fail-Safe System: Design a fail-safe system that accommodates the possibility of switch and/or power failure. FLOWLINE recommends the use of redundant backup systems and alarms in addition to the primary system. Flammable, Explosive or Hazardous Applications: EchoSpan should not be used within classified hazardous environments.

LM52-1400 (2” thread x 1” thread) or LM52-2400 (3” thread x 2” thread). Metal Tanks (LU80 series) Flowline ultrasonic transmitters have been optimized for use in non-metallic fittings. 1. For best performance, avoid the use of metallic fittings. a. Use a plastic 2” x 1” reducer bushing, such as the LM52-1400 or a plastic 1” flange, such as the LM52-1850 for metallic tanks. -
Page 18: Fitting Selection
Fitting Selection: Check the part number to determine the required fitting mount size and thread type. EchoSpan is commonly installed in tank adapters, flanges, brackets or standpipes. Note: Always include the gasket when installing the EchoSpan. 1. Tank Adapter: Select a tank adapter fitting, such as the LM52-1890 for the LU80 series or the LM52-2890 for the LU81, LU83 &... - Page 19 3. Flange (LU80 series): If installing on a flange, select a flange with a thread that is above the plane of the flange, such as the LM52-1850. a. The LU81, LU81 & LU83 series works well with Flange installations. b. Avoid the use of blind flanges with tapped threads or flanges where the threads are even with the plane of the flange, such as the Banjo 1"...
