SAFETY PRECAUTIONS
Step Three
About this Manual:
PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS PRODUCT.
This manual includes information on the EchoSonic® II series Ultrasonic Level transmitter from FLOWLINE.
Please refer to the part number located on the sensor 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 transmitter with the included Viton® gasket and never over tighten the transmitter 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 EchoSonic® II. 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 transmitter housing is liquid‐resistant the EchoSonic® II 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 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.
Safety
Installation should be done by properly trained staff
Supply voltage should never exceed a maximum of 28 VDC
Make sure the sensor is chemically compatible with your application
Design a fail‐safe system that accommodates the possibility of sensor and/or power failure.
This sensor should not be used in classified hazardous environments
Make a Fail‐Safe System:
Design a fail‐safe system that accommodates the possibility of transmitter
and/or power failure. FLOWLINE recommends the use of redundant backup systems and alarms in addition to
the primary system.
Flammable, Explosive or Hazardous Applications:
EchoSonic® II should not be used within classified
hazardous environments.
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.
