Introduction: The EchoSonic II 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. New Features Simple configuration with WebCal software, no more target calibration.
About this Manual: PLEASE READ THE ENTIRE QUICK START PRIOR TO INSTALLING OR USING THIS PRODUCT. This manual includes information on the EchoSonic II series Ultrasonic Level Switch from FLOWLINE. Please refer to the part number located on the switch label to verify the exact model configuration, which you have purchased. User’s Responsibility for Safety: FLOWLINE manufactures a broad range of level sensing technologies.
Warning: Always use the Viton gasket when installing the EchoSonic II, and make sure that all electrical wiring of the switch is in accordance with applicable codes. Components: EchoSonic II is offered in three different models. Depending on the model purchased, you may or may not have been shipped all the components shown below. You do however, need an EchoSonic II, USB® Fob and Viton® gasket to configure, install and operate EchoSonic II.

Getting Started: EchoSonic II is configured through WebCal, a PC software program. WebCal is a free download from Flowline’s website. You must download and install WebCal prior to plugging in the USB® Fob. Please go to http://www.flowline.com, click on WebCal Software and select your language version. WebCal System Requirements Windows® XP or 2000 10 mB hard drive space 256 mB RAM 1 USB® 2.
USB® Fob Interface EchoSonic II communicates with WebCal through a USB® interface called a Fob. Before plugging your Fob into your computer’s USB® port, be sure that you have installed WebCal on your computer. Connect the red, green, white and black wires from EchoSonic II into the correct terminals on the Fob. Tighten the screws on the terminals and plug your Fob into the USB® port of your computer.
WebCal Step 1: Configuration This section of WebCal is where you select the application’s configuration settings. Start from the top and work to the bottom, choosing the selections that are applicable to your configuration. “Not Applicable” will automatically show when a selection doesn’t apply to your configuration settings, and you may move on. All configuration settings must be selected or have “Not Applicable” before you can continue to step 2.
Output at Empty This feature allows you to select the orientation of the 4 to 20mA output (4 to 20 mA or 20 to 4 mA). Choose which output setting best fits the application. Typical installations are set with 4 mA at Bottom. This will not affect the performance of the sensor other than the output of the EchoSonic II. WebCal’s factory default is 4mA at bottom and 20mA at top. When connecting your sensor to a display, you must account for your output settings.
WebCal Step 2: Tank Levels This section of WebCal is where you enter application measurement values. All values must be filled in before moving to step 3. Sensor Height: Distance from the bottom of the tank to the bottom of the transducer. Fill Height: Distance from the bottom of the tank to the maximum liquid height. WebCal Step 3: Write to Unit After you have entered configurations and tank values, click “Write to Unit” and send the configuration to your EchoSonic.
Wiring Diagram Wiring EchoSonic II After you have finished positioning and mounting EchoSonic II, follow WebCal’s wiring diagram to wire EchoSonic II. Flowline recommends using a qualified licensed electrician to wire EchoSonic II and your application’s components. Wire Connections: Red & Black Red and Black leads are for connection to a 24 VDC power supply or to a 4-20 mA loop power source.
General notes for electrical connections, usage and safety: Where personal safety or significant property damage can occur due to a spill, the installation must have a redundant backup safety system installed. Wiring should always be completed by a licensed electrician. Supply voltage should never exceed 28 VDC. The sensor materials must be Chemically compatible with the liquids to be measured. Design a fail-safe system for possible sensor and/or power failure.

Installation The EchoSonic II should always be mounted perpendicular to the liquid surface and installed using the provided Viton mounting gasket. Make sure that the fitting and transmitter threads are not damaged or worn. Always hand-tighten the transmitter within the fitting. Perform an installed leak test under normal process conditions prior to system start up. Note: The preferred mounting fitting for the LU27 series is the LM52-1400 (2” thread x 1” thread) reducer bushing. Mounting Guide 1.
Installation in existing fittings If the existing fitting is larger than the threads of the EchoSonic II, select a reducer bushing such as the LM52-1400 (2” thread x 1” thread) or LM52-2400 (3” thread x 2” thread). Metal Tanks (LU27 series) Flowline ultrasonic transmitters have been optimized for use in non-metallic fittings. 1. For best performance, avoid the use of metallic fittings. a.
Note: Do not exceed the dimensions listed above 2. Flange (LU27 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 LU23, LU28 & LU29 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" Poly ANSI Flange (series AF100). c.
4. Stand Pipe: A standpipe maybe used to dampen turbulence or when foam is present in the application. a. Pipe can be made of any material. b. Select a minimum 3” ID pipe for the stand pipe. i. A 2” pipe is usable with the LU27 series, but is the minimum. ii. Pipes larger than 3” can also be used. c. Use a coupling and reducer bushing to attach the EchoSonic II to the pipe. i.
Advanced Features This tool is designed to help solve operational issues. Changing these setting will alter the performance of your unit. Please read through this HELP file to assist you in making adjustments or if still unclear about a specific issue, please contact FLOWLINE, Applications Engineering.
Decrease Output Filtering: Placing a check mark in the box will eliminate all filtering (averaging) of the analog output. Enables a pulse by pulse level reading. Use this filter to see changes in level after every sound pulse. Note: Never check increase output filtering and decrease output filtering at the same time. Stabilize Output in Deadband: Placing a check mark in the box will activate a filter to hold the output at Full if the level enters the dead band of the EchoPod.
Updating Transmitter Firmware WebCal software can also be used to update the firmware inside the EchoSonic II transmitter. This feature allows the transmitter to be updated when new features are added. First open WebCal with an EchoSonic II transmitter connected and the latest version of WebCal downloaded to your PC. Click on the Updates Tab and then click on Select Program to select the Firmware update. Select the latest version of the firmware file and click on OK.
