Introduction / Table of Contents Step One ® EchoWave utilizes TDR (Time Domain Reflectometry) technology. It is best described as low-energy, high- frequency electromagnetic impulses, generated by the sensor’s circuitry that is propagated along the probe as it is immerged in the liquid to be measured. Impulses hit the surface of the media and part of the impulse energy is reflected back up the probe to the circuitry.

3. DO NOT open the unit cover until it is time to calibrate. 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 a redundant backup system and alarm in addition to the primary system.
Getting Started Section Two SETUP OVERVIEW Below highlights the initial steps in setting up your sensor for operation. 1. Check Part Number (Section Two) a. Confirm that the sensor’s part number matches the ordered part number and all components are provided with the model delivered. 2.
Getting Started Section Two ® Components: EchoWave is offered in 12 different models. Depending on the model purchased, you may or may not have been shipped the configuration component shown below. Mat’l of Part Maximum Probe Thread Components Number Range Style Const.
Getting Started Section 2 UNDERSTANDING SENSOR HEIGHT ® This is a critical setting for EchoWave . Sensor Height defines the height of the sensor above the bottom of the tank. The height value must take into account the shape of the tank and any risers, fittings, structures or extensions associated with the tank or the installation (see examples below).
Page 10
Getting Started Section Two UNDERSTANDING INSTALL LOCATION LENGTH Measure the space below the actual installation location for the sensor. This distance (install length) must be greater than the probe length. In many tanks, the install length corresponds to the height of the tank. With dome top, cone bottom and horizontal tanks, include the added height of the curved surface.

Getting Started Section Two ADDING A RISER TO AVOID CUTTING THE PROBE In some conditions, a riser may be added to avoid cutting the probe. Rod and Cable Probes With the Rod and Cable versions Least Number of Fittings Too Many Fittings of the probe, the maximum height for the riser is 12”...
Getting Started Section Two UNDERSTANDING MEASUREMENT RANGE ® EchoWave level transmitters have small dead band areas at both the top and bottom of the probe. It is due to the presence of unavoidable signal disturbances at both ends of the probe. In these dead band areas the measurements are non-linear or have reduced accuracy.
Page 13
Getting Started Section Two UNDERSTANDING MINIMUM FILL-HEIGHT (PUTTING IT ALL TOGETHER) ® EchoWave has a Minimum Fill-Height (Min. Fill-H), which is measured from the bottom of the tank to the top of the Bottom Dead Band. As shipped from the factory, Min. Fill-H is where the 4mA current is located and is the lowest point on the probe where the sensor can detect a liquid level.
Getting Started Section Two DISTANCE (HEIGHT OF LIQUID) VS. VOLUME OF LIQUID ® With WebCal , the LG10/LG11 series can be configured to operate as a device that reads the distance (height of liquid) or volume of a liquid. The location of the empty current will adjust depending on which configuration method is selected.
Installation Section Three ® EchoWave is mounted vertically into the tank via its connection thread. It is then screwed directly into a standard threaded tank connection, i.e. tank adapter, bushing, weld-in socket, or it can be screwed into a flange which is connected to a tank nozzle. LG10/LG11 series should not be welded directly into the tank.

Installation Section Three MOUNTING CONSIDERATIONS (CONTINUED) The rod and cable probes are suitable for a very wide range of applications in liquids. However, the signal has a wider detection radius around the rod/cable. Therefore, it is more responsive for measurement signal disturbances that are overcome by a few Mounting Considerations (see below) as well as simple configuration adjustments to the sensor.
Installation Section Three INSTALLATION TIPS Tall and Narrow Risers Rod and Cable probes can be installed in tall and narrow risers under the following criteria: Nozzle Diameter must be >2” (50mm), Nozzle Height must be <12” (300mm), Riser must be metallic, ...
Page 18
Installation Section Three INSTALLATION TIPS (CONTINUED) Liquid Spray Rod and Cable probes must avoid any liquid that sprays or pours onto the probe. Coaxial probes are not affected by liquid straying on parts that are above the liquid surface. However, avoid installing probe where liquid will pour onto the probe.
Page 19
Installation Section Three INSTALLATION TIPS (CONTINUED) Non-Metallic Tanks Unlike coaxial, rod and cable probes have no containment mechanism. This energy must be contained by the tank wall, requiring that all rod and cable probe sensors be installed in metallic tanks or within below grade concrete sumps. Coaxial probes can be installed in any type of tank, including non- metallic tanks.
Page 20
Installation Section Three INSTALLATION TIPS (CONTINUED) Tall Tanks The rod and coaxial probes have a maximum insertion length of 9.8’ (3m). For metal or concrete tanks that are taller/deeper, the cable probe can be used for lengths up to 18.0’ (5.5m). ...
Wiring Section Four ® Analog Output (4-20 mA): The analog output of the EchoWave is a sourced 4-20 mA control circuit. The typical way to use this feature is to connect a positive supply to the (+) input terminal, a negative supply to the (-) input terminal and to connect the current output out of the 420 (+) terminal.

Empty Signal Scan Section Six EMPTY SIGNAL SCAN ® The empty signal Scan is a powerful disturbance signal suppression feature of EchoWave . The sensor scans its entire probe length for any disturbance/interference signals within the application that could potentially be misinterpreted as level readings by memorizing and suppressing them during operation.
Page 31
The Empty Signal Scan can be viewed with the WebCal software (version 6.5 and greater). Note: Always ® consult a Flowline representative for reviewing of the signal data. To view, follow the directions below: 1. Activate an empty signal scan (see instructions in Empty Signal Scan, Section 6).
It can be used to confirm the correct level reading by the sensor or to troubleshoot any false signals. There is a two step process involving the creating and viewing of an echo ® curve. Note: Always consult a Flowline representative for reviewing of the signal data. #1 - CREATE AN ECHO CURVE To create an echo curve, use the following instructions: 1.
Appendix Section Seven A. SENSOR CONFIGURATION LOOP FAIL-SAFE This feature allows you to select the fail-safe current output if the sensor looses echo confidence (LOST). When the sensor regains echo confidence, the output current will revert back to the current level condition.
Page 34
Appendix Section Seven A. SENSOR CONFIGURATION (CONTINUED) Startup Condition This feature allows you to select the startup current when power is first applied to the sensor. The sensor will consume the selected power while it is acquiring the liquid level. When the correct level has been identified, the output will adjust to the level output.
2 to 2.9 Note: It is very important to select the correct range for the dielectric value of the liquid. Choosing an incorrect range will affect the performance of the sensor. Reference a website such as http://flowline.com for dielectric information.

Appendix Section Seven CUTTING THE PROBE If the length of the probe is too long (touches bottom of tank, prevents the sensor from being threaded into the tank or a shorter length is required for the application), the probe can be cut to length in the field. Note: The most important requirement for cutting the probe is to protect the housing from being dropped, banging into other objects or swinging freely.
