Page 2: Table Of Contents
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. -

. 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. 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 7: Getting Started (Setup Overview)
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. -

Page 9: Probe Length
Getting Started Section Two 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.

Page 12: Measurement Range
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.

Page 14: Distance (Height Of Liquid) Vs. Volume Of Liquid
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. -
Page 15: Installation (Mounting Considerations)
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. Always use metal fittings with the Rod Probe (LG10-0 series) and Cable Probe (LG11- 2 series. - Page 16 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). ...

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 33 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).

Page 43: Cutting The Probe
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. Follow the instructions for the appropriate probe style. Place the probe on a sturdy surface. Measure and mark the location for the cut. Secure the rod to prevent it from moving during cutting. o Be sure to secure the housing to prevent it from moving when the probe is cut. Use a saw with a blade designed to cut 316L SS to cut the probe. o Examples include hack saw, diamond wheel rotary tool, etc. o Once the probe is cut, trim/file the fresh cut. Install the probe per mounting instructions. COAXIAL Place the probe on a sturdy surface. Measure and mark the location for the cut on the coaxial shield. Unthread the coaxial shield from the GWR sensor. ... - Page 44 Appendix Section Seven Measure and mark the location for the cut on the exposed rod. o Use the coaxial shield as a guide to confirm both cuts are at the same length. Cutting the rod o Secure the rod to prevent it from moving during cutting. ...
