About this Manual:
PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS PRODUCT. This
manual includes information on the EchoSpan 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. 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. The failure to do so could result in property damage or serious injury.
Proper Installation and Handling:
Only professional staff should install and/or repair this product. Install the switch with the included Viton
gasket and never over tighten the switch within the fitting. Always check for leaks prior to system start-up.
Wiring and Electrical:
A supply voltage of 12 to 28 VDC is used to power the EchoSpan. Electrical wiring of the transmitter should
be performed in accordance with all applicable national, state, and local codes.
Material Compatibility:
The enclosure is made of Polycarbonate (PC). The transducer is made of Polyvinylidene Fluoride (PVDF).
Make sure that the model, which you have selected, is chemically compatible with the application media.
Enclosure:
While the switch housing is liquid-resistant the EchoSpan is not designed to be operational when immersed. It
should be mounted in such a way that the enclosure and transducer do not come into contact with the
application media under normal operational conditions.
The enclosure has a flip cover with dual 1/2” NPT female conduit ports and an internal terminal strip for wiring.
To open the enclosure, you will need a small insertion tool such as a screwdriver. Loosen the locking screw
located at the top front of the enclosure. Rotate the hinged cover up for 135° access to the faceplate and
terminal strips. Before closing the enclosure, make sure that the enclosure gasket is properly seated, and that
any conduit fittings, cable connectors or plugs are installed correctly and sealed.
Handling Static-Sensitive Circuits/Devices:
When handling the transmitter, the technician should follow these guidelines to reduce any possible electrostatic
charge build-up on the technician’s body and the electronic part.
1. Always touch a known good ground source before handling the part. This should be repeated while
handling the part and more frequently after sitting down from a standing position, sliding across the seat
or walking a distance.
2. Avoid touching electrical terminals of the part unless making connections.
3. DO NOT open the unit cover until it is time to calibrate.
