Welcome to the EchoSonic® II Quick Start The EchoSonic® II quick start is meant to show some of the more common setup solutions to getting the EchoSonic® II up and running quickly. If you run into an issue that is not addressed here or wish to install or set up with a non‐standard configuration, please address the EchoSonic® II Manual or refer to the Flowline website at www.flowline.com. We Do Your Level Best Thank you for purchasing Flowline’s EchoSonic® II.
Configuring the EchoSonic® II Configuration of your sensor should be performed prior to mounting, since it requires connection to your PC. Step 1: Install the WebCal Software Download WebCal from www.flowline.com onto a PC with the following minimum specifications: Windows® 2000/XP/Vista/7/8, 10 MB storage space, 256 MB RAM, 1 USB 2.0 port Double‐click the WebCal icon to install before proceeding to Step 2.
Step 3: Configure through WebCal These instructions will walk you through configuration of the sensor through WebCal. For more information, click the WebCal HELP button in the lower right corner or anywhere on the WebCal screen or refer to the EchoSonic® II manual found at www.flowline.com.
Using the drop‐down menus on the left of the WebCal screen set the configuration for your application requirements. When a selection does not apply to your application, “Not Applicable” will appear in the drop‐down. Make sure all drop‐downs are set appropriately for your application before moving to the Tank Level section. Loop Fail Safe. Use this setting to choose the output level should the sensor not receive an echo. Output at Empty. Use this setting to change the 4‐20 mA setting from its default.
Enter the appropriate tank level set points for your application. Units. Display measurements in inches or centimeters. Sensor Height. Distance measured from the bottom of the empty tank to the bottom of the transducer. Under factory configuration, this becomes the 4 mA set point. Fill Height. Distance measured from the bottom of the empty tank to the maximum fill height within the tank. Under factory configuration, this becomes the 20 mA set point.
The Advanced button is used for options available when setting up the sensor with special, non‐standard features. Many of these features are available for specific applications that may change from time to time. Consult WebCal's HELP file for the latest information on the use of any of these features. The more commonly used Advanced features are the Invert Relay and Increase Output Filtering described below. Increase Output Filtering.
Mounting the EchoSonic® II The sensor should always be mounted perpendicular to the liquid surface using the provided Viton® mounting gasket. Insure that there are no restrictions or obstacles in the path of the ultrasonic signal. Further mounting information can be found on the Flowline website at www.flowline.com. The EchoPod® has a 1” NPT or G fitting and requires more care in mounting to reduce any coupling of the ultrasonic signal to the mounting structure. The below listed fittings are recommended.
Mounting with a Stand‐Pipe: A stand‐pipe may be used to dampen turbulence, separate surface foam from the point of measurement or increase performance in heavy vapor. When mounting the sensor in a stand‐pipe, the minimum diameter of the pipe is 2”. Larger diameter pipes can be used. The pipe should be attached with a coupling and reducer bushing. The pipe length should run the measurement span and the bottom of the pipe should remain submerged at all times to prevent foam from entering the pipe.
Wiring the EchoSonic® II After mounting the sensor, make the necessary electrical connections. A wiring diagram with specific recommendations for the sensor’s configuration can be printed from the WebCal program. A typical wiring diagram is shown on the next page. Red (Power) and Black (Return) leads are for connection to a 24 VDC power supply or to a 4‐20 mA loop power source.
Wiring the EchoSonic® II The following wiring diagram can be used when wiring to the EchoSonic® II relays. Typical Wiring Diagram Your WebCal Wiring Diagram may vary. 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.
